This week’s digest covers five items spanning diagnostic testing, treatment approaches, and the relationship between tinnitus and mental health. Two items are registered trials without published results yet. The remaining three offer data on clinical differences between male and female patients, auditory training therapy, and the shared neurological pathways linking tinnitus with depression and anxiety. Taken together, they reflect the breadth of ongoing work in tinnitus research without offering near-term changes to clinical practice.
Tinnitus Types: Pulsatile Tinnitus
A rhythmic sound in sync with your heartbeat. Unlike other tinnitus forms, pulsatile tinnitus often has a treatable vascular cause.

Tinnitus Research Digest: Mental Health Burden, Integrated Care, and Medication-Linked Cases
This week’s digest covers four areas relevant to tinnitus patients and clinicians: a cross-sectional study on mental health burden in tinnitus clinic attendees, a small pilot trial of an integrated management framework, a case report on pulsatile tinnitus linked to an acne medication, and an educational case report on Ménière’s disease. No single item represents a treatment advance, but together they reflect the importance of addressing tinnitus as a condition with psychological, audiological, and medical dimensions.

Tinnitus and Pregnancy: Hormonal Changes, Risks, and Safe Management
That Ringing in Your Ears Is Real — and More Common Than You Think
Tinnitus affects around 1 in 3 pregnant women due to hormonal shifts, a 40–50% increase in blood volume, and fluid retention that disrupts inner ear function (Feroz et al. (2025); Tinnitus (2024)). In most cases, it resolves or significantly reduces after delivery. New-onset tinnitus accompanied by sudden headache, visual disturbances, or swelling during pregnancy should be reported to a midwife or GP promptly, as it can signal gestational hypertension or preeclampsia.
That Ringing in Your Ears Is Real: More Common Than You Think
Noticing a new sound in your ears when you are pregnant is frightening. Your instinct is to wonder whether it means something is wrong — with you, or with your baby. That reaction makes complete sense. Pregnancy heightens your awareness of every bodily change, and tinnitus is not a symptom you can easily ignore.
Here is the reassurance you need first: ringing, buzzing, or hissing in the ears is one of the most common ear complaints in pregnancy. More than 1 in 3 pregnant women experience it (Tinnitus (2024)), compared to around 1 in 10 women of similar age who are not pregnant. For the vast majority, it is driven by identifiable physiological changes, not a sign that anything has gone seriously wrong.
This article explains what is actually happening in your body to cause the sound, gives you a clear picture of which symptoms warrant urgent medical contact, and covers what you can safely do to get some relief.
Why Pregnancy Causes Tinnitus: Three Distinct Pathways
Pregnancy puts your cardiovascular and hormonal systems under significant demand, and your inner ear is sensitive to both. There are three main physiological routes through which these changes produce tinnitus.
Hormonal changes and the inner ear
Oestrogen and progesterone rise substantially during pregnancy and directly influence the fluid environment of the cochlea, the spiral structure in your inner ear that converts sound waves into nerve signals. These hormones alter how nerve cells in the auditory pathway respond to sound. When that balance shifts, the brain can begin generating phantom sounds (Swain et al. (2020)).
Cardiovascular changes and pulsatile tinnitus
Blood volume increases by 40–50% during pregnancy to support the placenta and growing baby (Tinnitus (2024)). This raises the pressure of fluid within the cochlea and increases blood flow through the vessels surrounding the inner ear. For some women, the result is pulsatile tinnitus: a rhythmic sound that pulses in time with the heartbeat. If the sound you are hearing has a pulse or beat to it rather than being a steady tone, mention this specifically to your midwife or GP, as it may warrant a cardiovascular check.
Fluid retention and endolymphatic hydrops
Pregnancy causes widespread fluid retention, and the inner ear is not exempt. Increased fluid in the membranous labyrinth raises pressure in the endolymph, the fluid that fills the inner ear’s balance and hearing chambers. Researchers have compared this mechanism directly to Ménière’s disease, which is caused by a similar build-up of endolymphatic pressure (PMC (2022)). This is why some pregnant women also experience a sensation of ear fullness or mild dizziness alongside tinnitus.
A correctable fourth factor: iron-deficiency anaemia
Iron-deficiency anaemia is common in pregnancy, and it is worth knowing that anaemia can independently contribute to tinnitus. If your prenatal blood tests show low iron, treating the anaemia may reduce the tinnitus alongside it.
One more figure worth knowing: if you had tinnitus before becoming pregnant, the odds are that pregnancy will make it louder or more persistent. Two in three women with pre-existing tinnitus report their symptoms worsen during pregnancy, particularly in the second trimester (Tinnitus (2024)).
When to Act Immediately: The Preeclampsia Red Flag
Tinnitus alone, without any other symptoms, is not an emergency. Raise it at your next midwife appointment, but there is no need to call 999 or rush to A&E.
The picture changes when tinnitus appears alongside other symptoms. Tinnitus can be an early warning sign of gestational hypertension and preeclampsia, a serious condition affecting approximately 3–5% of pregnancies in the UK (NICE (2019)). International clinical guidelines list tinnitus explicitly among the urgent warning signs of hypertensive disorders in pregnancy (MSF (2023)).
Contact your midwife, maternity unit, or GP the same day — or call 999 if symptoms are severe — if tinnitus occurs alongside any of the following:
- Sudden or severe headache
- Visual disturbances: blurred vision, flashing lights, or seeing spots
- Severe pain just below your ribs
- Nausea or vomiting alongside the above
- Sudden swelling of your face, hands, or feet
- Reduced fetal movement
These are the official emergency symptoms listed in NICE guidance for preeclampsia (NICE (2019)), and tinnitus appearing in this cluster adds urgency to any of them.
If your tinnitus is a steady tone without any of the symptoms above, the appropriate step is to mention it at your next scheduled appointment. You do not need to catastrophise, but you should not dismiss it either. Telling your midwife means it gets noted in your records and monitored.
If you experience tinnitus together with sudden severe headache, visual disturbances, severe pain below your ribs, or sudden facial or hand swelling, contact your midwife or maternity unit the same day. If symptoms are severe, call 999. These may be signs of preeclampsia.
Which Trimester? How Tinnitus Changes Through Pregnancy
Tinnitus can begin at any point in pregnancy, but the pattern across trimesters follows the body’s physiology fairly closely.
In the first trimester, rapid hormonal shifts can trigger early-onset tinnitus, often alongside other vestibular symptoms like dizziness (PMC (2022)). Many women also notice ear fullness during this phase.
The second and third trimesters bring the highest burden. A large prospective study of 1,230 pregnant women found tinnitus most common in the third trimester, when blood volume and fluid retention are at their peak (Feroz et al. (2025)). Women with pre-existing tinnitus tend to notice a worsening particularly in months four to six (Tinnitus (2024)).
What about after delivery and during breastfeeding?
This is an aspect that rarely gets covered, but it matters. For most women, tinnitus improves or resolves within weeks of delivery as hormones and blood volume normalise. A comparison of 33% tinnitus prevalence in pregnancy versus 11% in non-pregnant women of similar age, with relief documented after delivery, supports this pattern (Swain et al. (2020)).
If tinnitus does not disappear immediately after birth, that does not mean it is permanent. The postpartum and breastfeeding period involves significant ongoing hormonal flux, and sleep deprivation and new-parent stress compound matters further. Tinnitus may persist or temporarily change during this phase (Tinnitus (2024)). Allow several weeks to months after delivery, or after breastfeeding ends, before drawing any conclusions about whether the tinnitus is here to stay. If it persists beyond that point, a referral for a full hearing assessment is the right next step.
If you are still experiencing tinnitus weeks after giving birth, you are not alone. The postpartum hormonal transition takes time, and tinnitus often lags behind the delivery itself. Mention it at your postnatal check if it has not resolved.
Safe Ways to Manage Tinnitus During Pregnancy
No pregnancy-specific clinical trials have tested tinnitus management strategies, so the guidance below is based on general tinnitus evidence, known safety profiles in pregnancy, and clinical consensus. The aim is relief, not a cure, and several options are both safe and practical.
Sound enrichment
Using background sound to reduce the contrast between silence and the tinnitus signal is one of the most widely recommended strategies in tinnitus management, and it carries no drug interactions or risks in pregnancy. White noise machines, a fan, nature soundscapes, or low-volume background music can all help, particularly at night when tinnitus tends to be most disruptive. Sound enrichment apps on a smartphone work equally well.
Stress and sleep management
Stress amplifies tinnitus perception, and pregnancy brings its own pressures. Prenatal yoga, guided breathing, and mindfulness practices are generally safe in pregnancy and may reduce the distress associated with tinnitus, even if they do not reduce the sound itself. Your midwife or GP can advise on local classes.
Dietary iron and prenatal vitamins
If blood tests suggest iron-deficiency anaemia, addressing it through diet (dark leafy greens, red meat, legumes, fortified cereals) and your prescribed prenatal vitamins is worthwhile. Iron-deficiency anaemia is independently associated with tinnitus and can be corrected safely during pregnancy under your care team’s guidance.
Hydration
Adequate fluid intake supports overall circulatory health and may help moderate the fluid retention effects that contribute to inner ear pressure changes. Aim for the recommended daily fluid intake for pregnancy.
When to seek a hearing assessment
If tinnitus is causing significant distress, is affecting your sleep night after night, or is accompanied by any change in your hearing, ask for a referral to audiology through your midwife or GP. This is a legitimate clinical request, not an overreaction.
For safe tinnitus relief during pregnancy: use background sound at night, manage stress with prenatal mindfulness or yoga, ensure your iron levels are checked, and stay well hydrated. None of these carry risks in pregnancy.
What to avoid or discuss with your doctor first
Some commonly suggested tinnitus remedies are not appropriate during pregnancy:
- Ginkgo biloba: Frequently marketed for tinnitus, but considered likely unsafe in pregnancy due to an increased risk of bleeding and possible stimulation of early labour. Do not take it without explicit approval from your prescriber.
- High-dose vitamin supplements: Beyond your prescribed prenatal vitamins, high-dose single vitamins (including high-dose zinc) have not been established as safe or effective for tinnitus in pregnancy. Stick to your prescribed supplement.
- Any over-the-counter medication: Always check with your GP or midwife before taking any OTC remedy for tinnitus symptoms during pregnancy.
Most Pregnancy Tinnitus Resolves, But You Don’t Have to Wait It Out Alone
Tinnitus during pregnancy is common, physiologically explained, and in most cases temporary. It is not a sign that something is wrong with your baby, and for the large majority of women it reduces or disappears after delivery or during the weeks that follow.
You now know which symptoms alongside tinnitus require same-day contact with your maternity team or GP. You know that a steady tone without other red-flag symptoms is worth noting at your next appointment rather than rushing to A&E. And you have a set of practical, pregnancy-safe strategies to make the sound more manageable while you wait for your body to settle.
Do not file this away as a minor complaint you hesitate to mention. Tinnitus in pregnancy is a legitimate clinical concern, and your midwife needs to know about it. Mention it at your next appointment, and if any of the red-flag symptoms appear alongside it, do not wait.

Tinnitus Symptoms: When Ear Ringing Requires Urgent Medical Attention
That Ringing in Your Ears: When to Worry and When to Wait
A sudden change in the sounds you hear — or a new ringing, buzzing, or whooshing that wasn’t there before — can be genuinely frightening. The question “is this serious?” is a completely reasonable one to ask. The honest answer is that most tinnitus is not dangerous. But a small number of presentations are time-sensitive, and acting quickly in those cases can make a real difference to your hearing and your health.
This article walks you through a three-tier decision guide: symptoms that require emergency care right now, symptoms that need specialist review within 24 to 48 hours, and symptoms where a routine GP appointment within two weeks is the right step. Knowing which category fits your situation means you can act calmly and decisively.
Which Tinnitus Symptoms Are Red Flags?
Most tinnitus is not dangerous, but certain tinnitus symptoms signal conditions where how quickly you act changes outcomes. Go to A&E or call 999 immediately if you have tinnitus with sudden facial weakness, drooping, or confusion (possible stroke), tinnitus after a head injury, or a new heartbeat-synced whooshing sound (pulsatile tinnitus). See an ENT doctor within 24 hours if you notice sudden hearing loss alongside tinnitus in one ear — steroid treatment works best when started as soon as possible, and the window for effective treatment closes after about two weeks. Book a GP appointment within two weeks for one-sided tinnitus with no obvious cause, tinnitus causing significant sleep disruption or distress, or new persistent tinnitus that has lasted more than a few days.
Emergency: Go to A&E or Call 999 Now
The following presentations require immediate emergency department assessment. They are uncommon, but acting the same day matters.
Sudden facial weakness, drooping, numbness, or confusion alongside tinnitus. These are warning signs of stroke. Use the FAST check: Face drooping, Arm weakness, Speech difficulty, Time to call 999. Tinnitus appearing alongside any of these symptoms is a neurological emergency.
Tinnitus following a head or neck injury. Even if the injury seemed minor, tinnitus after trauma can indicate a base-of-skull fracture or damage to the structures of the inner ear. An emergency CT scan is needed to assess this (Hoare & et (2022)).
New-onset pulsatile tinnitus — a heartbeat-synced whooshing or thumping sound that has appeared suddenly. This type of tinnitus can indicate a vascular emergency, including an arteriovenous malformation or arterial dissection. Sudden-onset pulsatile tinnitus warrants emergency MR angiography and should not be waited on (Hoare & et (2022)).
Acute severe vertigo with neurological symptoms alongside tinnitus. Severe spinning, loss of balance, and difficulty coordinating movement combined with tinnitus can indicate a cerebellar event or stroke. Go to A&E without delay.
These four presentations are uncommon, but they are the situations where acting immediately, rather than waiting to see a GP in the morning, can be the difference between a good recovery and serious lasting harm.
Urgent: See an ENT or GP Within 24–48 Hours
Sudden hearing loss alongside tinnitus in one ear. Sudden sensorineural hearing loss (SSHL) is hearing that drops noticeably over a period of up to 72 hours. It often arrives alongside tinnitus, and sometimes a feeling of ear fullness. Hoare & et (2022) describe SSHL as an “otological emergency” and state that “high-dose oral corticosteroids should be commenced prior to specialist assessment.” Research shows that corticosteroid treatment is most effective when started as soon as possible — the evidence indicates no significant difference in outcomes within the first 14 days, but effectiveness drops dramatically after that point (Frontiers in Neurology (2023)). A meta-analysis of 20 randomised controlled trials confirmed that steroid treatment significantly improves hearing recovery, with combined intratympanic and systemic steroids producing the best results (Li & Ding (2020)). Do not wait to see whether the hearing returns on its own — around one-third to two-thirds of people do recover some hearing without treatment, but those who do not will have a much smaller chance of recovery if treatment is delayed past two weeks.
Pulsatile tinnitus of any kind. Any rhythmic thumping or whooshing that pulses in time with your heartbeat needs investigation for a vascular cause, even if it didn’t appear suddenly. Around 30–50% of people with pulsatile tinnitus have an identifiable underlying cause, and CT angiography has approximately 86% diagnostic yield in identifying it (Yew (2021)). This is a different diagnostic pathway from a standard hearing test — your doctor needs to know the sound is pulsatile so the right imaging is ordered.
New one-sided tinnitus with hearing change. Tinnitus in one ear only, particularly when accompanied by any change in hearing, warrants audiometry and a possible MRI of the internal auditory canal. The absolute risk of an acoustic neuroma (vestibular schwannoma) is low — a meta-analysis of 1,394 patients found a detection rate of just 0.08% on MRI for unilateral tinnitus without hearing asymmetry (Javed et al. (2023)) — but detecting even a small tumour early allows conservative monitoring rather than surgery. NICE guidelines recommend considering MRI for unilateral or asymmetric tinnitus even in the absence of other symptoms (NICE Guidelines (2020)).
Within Two Weeks: Book a GP Appointment
Not every concerning presentation is an emergency. These situations are clinically important and deserve proper attention, but a routine GP appointment within a fortnight is appropriate.
Tinnitus causing severe distress, sleep disruption, anxiety, or low mood. Tinnitus and mental health are closely linked — research shows that around 20% of people with tinnitus report suicidal thoughts, compared to approximately 13% in the general population, and depression significantly amplifies that risk (Brüggemann & et (2019)). If you are experiencing thoughts of suicide or self-harm, please contact a crisis line now — call the Samaritans on 116 123 or dial NHS 111. You do not need to wait for a GP appointment to get support.
Progressive hearing loss developing over days to weeks. Hearing loss that is getting worse gradually, rather than appearing suddenly, still requires ENT assessment and audiometry. It does not carry the same immediate urgency as SSHL, but a two-week window is appropriate — do not leave it for months.
New tinnitus lasting more than a few days with no obvious cause. If your tinnitus appeared without a clear trigger (no recent loud noise, no ear infection, no new medication), and it has persisted for more than a few days, a GP visit is worth arranging. Many reversible causes exist — earwax build-up, blood pressure changes, and medication side effects among them. Catching these early usually means simpler management.
The 48-Hour and 72-Hour Rules: Why Timing Matters
You may have seen references to a “72-hour window” for tinnitus and hearing loss. The reality is a little more precise, and understanding it helps explain why the urgency tiers above are structured as they are.
With sudden sensorineural hearing loss, the cochlea’s hair cells and auditory nerve can be injured by reduced blood supply or inflammation. Corticosteroids reduce that inflammation — but they work best when given early. The research shows that there is no significant difference in treatment outcomes when steroids are started any time within the first 14 days. After 14 days, however, the effectiveness of steroid treatment drops sharply (Frontiers in Neurology (2023)). This is why SSHL is treated like a cardiac event: not because every hour counts in the same way a heart attack does, but because the treatment window is real and finite, and waiting to see whether the hearing comes back on its own risks closing that window permanently.
With pulsatile tinnitus, the urgency is different in character. Some causes — like a benign venous hum — are not dangerous. Others, including arteriovenous fistulas or arterial dissection, carry a risk of stroke or haemorrhage that can worsen rapidly (Yew (2021)). This is why pulsatile tinnitus goes straight to vascular imaging rather than a standard audiogram. The goal is not to alarm you, but to identify the small proportion of cases where the underlying cause is serious before it progresses.
Summary: A Quick-Reference Guide to Tinnitus Red Flags
Here is a plain-language summary you can return to quickly.
EMERGENCY — call 999 or go to A&E now:
- Tinnitus after a head or neck injury
- Sudden facial weakness, drooping, or confusion (stroke symptoms)
- A new heartbeat-synced whooshing sound (sudden pulsatile tinnitus)
- Acute severe vertigo with neurological signs
- Tinnitus with thoughts of suicide or self-harm (call Samaritans: 116 123 or NHS 111)
URGENT — see an ENT or GP within 24–48 hours:
- Sudden hearing loss in one ear, with or without tinnitus
- Pulsatile tinnitus of any kind
- New one-sided tinnitus with a change in hearing
ROUTINE GP — within two weeks:
- Tinnitus causing significant distress, anxiety, or sleep disruption
- Gradually worsening hearing over days to weeks
- New persistent tinnitus with no obvious cause
For most people, tinnitus is not a sign of anything dangerous. But knowing when to act quickly means you are equipped to protect your hearing and your health when it counts.

Pulsatile Tinnitus: Causes, Symptoms, and When to See a Doctor
What Is That Rhythmic Sound in Your Ear?
Noticing a sound that pulses in time with your own heartbeat is unsettling in a way that ordinary ear ringing simply is not. It feels less like a glitch in your hearing and more like a signal — something your body is trying to tell you. The good news is that this instinct is not entirely wrong: unlike the constant ringing of common tinnitus, pulsatile tinnitus usually has a real physical cause, and real causes can be investigated and often treated. This article explains what pulsatile tinnitus is, what causes it, how to recognise it, and which specific symptoms mean you need to act today versus this week versus at your next convenient opportunity.
Pulsatile Tinnitus in a Nutshell
Pulsatile tinnitus is a rhythmic whooshing, thumping, or beating sound in one or both ears that synchronises with your heartbeat. Unlike ordinary tinnitus, it typically reflects a genuine physical sound source — turbulent blood flow near the inner ear, or a structural vascular abnormality. It accounts for fewer than 10% of all tinnitus presentations and affects roughly 4% of the population (White, 2025). With comprehensive imaging, an identifiable cause is found in up to 70% of cases, though estimates vary by imaging protocol. Because some causes range from benign venous anomalies to life-threatening vascular conditions such as dural arteriovenous fistulas, every new case warrants medical evaluation.
How Pulsatile Tinnitus Differs from Ordinary Tinnitus
Ordinary tinnitus is a phantom sound. No physical vibration is reaching your cochlea — your auditory nervous system is generating the perception of sound internally, usually because of changes in how it processes signals after noise damage, ageing, or other triggers. There is nothing physically there to hear.
Pulsatile tinnitus is different in a fundamental way: it typically reflects turbulent blood flow close enough to the structures of the inner ear that a genuine, if faint, physical sound is transmitted. Your ear is picking something up — it just happens to be inside your own body.
Clinicians further divide pulsatile tinnitus into two subtypes, and the distinction matters:
Objective pulsatile tinnitus can be heard by an examiner using a stethoscope held near the ear or neck. If a doctor can hear it too, a structural vascular abnormality is almost certainly present.
Subjective pulsatile tinnitus is heard only by the patient. This is the more common presentation. It can still reflect a structural cause, but it may also indicate elevated pressure within the skull — a condition called idiopathic intracranial hypertension (IIH), which has its own distinctive features (Pegge et al., 2017).
This objective/subjective distinction shapes the urgency and type of investigation your doctor will pursue. Mentioning to your GP whether anyone else has been able to hear the sound is genuinely useful clinical information.
What Causes Pulsatile Tinnitus?
The causes of pulsatile tinnitus span a wide range, from minor anatomical variations to serious vascular conditions. Organising them by how likely they are — and how urgently they need attention — gives a clearer picture than a generic list.
Venous causes (most common, generally benign)
Venous anomalies account for approximately 48% of pulsatile tinnitus cases (Cummins et al., 2024). The most common culprits are sigmoid sinus diverticulum or dehiscence (a small pouch or thinning in the bony wall of a venous sinus near the ear), a high-riding jugular bulb, and transverse sinus stenosis. Blood passing through or near these structures creates audible turbulence. A useful clue: if pressing gently on the side of your neck reduces or stops the sound, a venous cause is more likely (Cummins et al., 2024). These conditions are not life-threatening, and treatments — including venous sinus stenting — have a strong track record.
Systemic and metabolic causes
Anything that increases the speed of blood flow through the vessels near your ear can cause pulsatile tinnitus. High blood pressure, severe anaemia, an overactive thyroid (hyperthyroidism), and pregnancy all fall into this category. The sound may come and go depending on activity, stress, or heart rate. Addressing the underlying condition often resolves the tinnitus.
Arterial causes (moderate concern)
Atherosclerosis — the build-up of plaques in arterial walls — creates turbulent flow that can become audible. A 1999 University of Wisconsin Stroke Program study found that severe carotid stenosis of 70% or more was present in 59% of patients with pulsatile tinnitus, compared with 21% of those without it (Hafeez et al., 1999). This association means arterial causes deserve investigation, particularly in older patients with cardiovascular risk factors. The study is now 25 years old and predates modern vascular imaging, but the clinical association remains accepted.
Idiopathic intracranial hypertension (IIH)
IIH is elevated pressure within the skull without an obvious cause. It most commonly affects younger women who are overweight. The classic triad is pulsatile tinnitus, persistent headache (often worse when lying flat), and visual disturbances. One 2025 study found that in patients whose IIH first presented as pulsatile tinnitus, visual symptoms were present in only around 25% of cases at the time of diagnosis — compared with 90% in typical IIH presentations (Coelho, 2025). This means the full triad may be absent early on; headaches and PT alone should prompt consideration of IIH.
Paraganglioma (glomus tumour)
A paraganglioma is a vascular tumour that can develop behind the eardrum or in the jugular bulb. On otoscopy, it may appear as a pulsating reddish mass visible through the eardrum. It is rare but has a characteristic appearance that an ENT doctor can identify quickly (Pegge et al., 2017).
Dural arteriovenous fistulas and arteriovenous malformations (serious — high red-flag signal)
Dural arteriovenous fistulas (dAVFs) and arteriovenous malformations (AVMs) are abnormal connections between arteries and veins inside the skull. Blood passing through these connections at arterial pressure generates a high-pitched sound. Together, shunting lesions of this type account for around 20% of pulsatile tinnitus cases (Cummins et al., 2024).
The combination of a patient-reported high-pitched quality and a bruit that an examiner can hear is a strong warning signal. A 2024 DSA-validated study of 164 patients found that this combination predicted the presence of a shunting lesion with an area under the ROC curve (AUROC) of 0.882, meaning it is a clinically meaningful predictor (Cummins et al., 2024). If your tinnitus is high-pitched and someone else can hear it too, this requires urgent specialist evaluation.
Recognising the Symptoms
Most people with pulsatile tinnitus describe a whooshing, thumping, or drumming sound — like wind passing through a tunnel, or the muffled sound of your own pulse. Some describe it as hearing their heartbeat inside their ear. It is rhythmically regular, and you can usually confirm the synchrony by checking whether the sound speeds up when your heart rate increases after exercise or anxiety.
Pulsatile tinnitus is more often one-sided (unilateral) than bilateral, which is itself a diagnostic pointer. Unilateral tinnitus of any kind is a red flag under the AAO-HNS 2014 clinical practice guideline (Tunkel, 2014).
Several accompanying symptoms carry specific diagnostic weight:
- Headaches, especially those that worsen when you lie down or first thing in the morning, raise suspicion of raised intracranial pressure (IIH).
- Visual disturbances — brief greyouts of vision, double vision, or persistent blurring — alongside PT suggest IIH or a vascular cause requiring prompt attention.
- A sound that others can hear: if a family member or doctor can detect the sound near your ear or neck without a stethoscope, this is objective PT and points strongly to a structural vascular source.
- Sensation without sound: some patients notice a rhythmic pressure or pulsing rather than a clear sound — this is still worth reporting.
In contrast to the hissing or ringing of ordinary tinnitus, pulsatile tinnitus rarely varies much between quiet and noisy environments. It is driven by your own circulation, not by external sound levels.
When Should You See a Doctor — and How Urgently?
This is where generic medical advice often falls short. “See your doctor if symptoms persist” is not enough for a condition that can range from benign to life-threatening. Here is a clearer guide.
Go to the emergency department immediately
Seek emergency care without delay if your pulsatile tinnitus began suddenly, particularly if it is accompanied by any of the following: severe headache (especially described as the worst of your life), sudden vision changes or loss, facial weakness or numbness, slurred speech, dizziness or loss of balance, or if it followed a head or neck injury. These combinations can indicate a dural arteriovenous fistula, arterial dissection, or another vascular emergency. Sudden-onset pulsatile tinnitus warrants immediate emergency assessment and MR angiography (Pegge et al., 2017).
See your GP urgently (within days)
Contact your GP within a few days — not weeks — if:
- Your pulsatile tinnitus is new and has been constant rather than intermittent from the start
- It has been getting worse over several weeks
- It is accompanied by headaches and/or visual changes, even without dramatic neurological symptoms
- You can hear it clearly even in noisy environments
These features raise concern for IIH, a growing vascular lesion, or early-stage carotid disease. An urgent referral to ENT or neurology is appropriate.
Make a routine GP appointment
If your symptoms are intermittent, have not been worsening, and are not accompanied by neurological symptoms, a routine GP appointment is a reasonable starting point. Ask specifically for an ENT referral — GPs may not always offer this automatically for intermittent symptoms, but given that pulsatile tinnitus is a formal imaging red flag under the AAO-HNS 2014 guideline (Tunkel, 2014), a referral is warranted.
At your evaluation, expect:
- A cardiovascular history and blood pressure check
- Otoscopy — the doctor looks through the ear canal for a retrotympanic pulsating mass
- A hearing test (audiogram)
- A check for a bruit using a stethoscope near the ear, temple, or neck
- Discussion about imaging referral
Diagnosis and What to Expect
The diagnostic pathway for pulsatile tinnitus is more structured than many patients realise. You are not just waiting to be believed — there is a specific sequence of investigations designed to find the cause.
First step — your GP: History-taking focused on onset, quality (high-pitched or low?), whether it stops with neck pressure, accompanying symptoms, and cardiovascular risk factors. Blood pressure will be checked and blood tests may screen for anaemia or thyroid problems.
ENT examination: An ENT specialist will perform otoscopy to look for a paraganglioma (the pulsating reddish mass that can be visible through the eardrum) and will attempt to auscultate for a bruit. A formal audiogram is standard.
Imaging pathway: The sequence depends on the clinical picture (Pegge et al., 2017):
- MRI and MRA (magnetic resonance imaging and angiography) is first-line. It evaluates the brain, intracranial vessels, and signs of raised intracranial pressure without radiation.
- CT of the temporal bone is added when an osseous cause is suspected — sigmoid sinus anomalies, superior semicircular canal dehiscence, or a glomus tumour in the middle ear structure.
- 4D-CTA or digital subtraction angiography (DSA) is reserved for cases where MRI/MRA is inconclusive or when a shunting lesion is strongly suspected and treatment is being planned. DSA is the gold standard but is invasive; it is not used as a first-line test.
With a comprehensive imaging protocol, an identifiable cause is found in up to around 70% of pulsatile tinnitus cases, though estimates in the literature range from 30–50% with less intensive workups (White, 2025). If your initial scans come back clear, that is genuinely reassuring — it substantially lowers the probability of a serious vascular cause. Your doctor may then consider watchful waiting with a low threshold to re-image if symptoms change.
When a cause is found, treatment is often effective. A systematic review of 28 studies covering 616 patients found that cerebral venous sinus stenting improved pulsatile tinnitus in 91.7% of cases (Schartz et al., 2024).
Key Takeaways
- Pulsatile tinnitus beats in time with your heartbeat and is a distinct condition from ordinary tinnitus — it typically reflects a physical cause such as turbulent blood flow or a vascular structural change.
- Common causes range from benign venous anomalies to serious arterial conditions. With comprehensive imaging, an identifiable cause is found in up to around 70% of cases.
- The danger spectrum matters: a high-pitched quality combined with a sound that an examiner can also hear is a strong predictor of a life-threatening shunting lesion (dAVF/AVM) and needs urgent specialist evaluation (Cummins et al., 2024).
- Sudden-onset pulsatile tinnitus is a medical emergency — go to the emergency department. New, persistent, or worsening PT warrants a GP appointment within days.
- A clear diagnostic pathway exists: ENT examination plus hearing test plus MRI/MRA is the standard starting point, with further imaging added as the clinical picture requires.
Pulsatile tinnitus is frightening to experience — but unlike most forms of tinnitus, it is one of the most investigable. When a cause is found, it can often be treated.

Noise in Your Ears But Not Tinnitus: What Else Could It Be?
That Noise in Your Ear — It Might Not Be Tinnitus
Hearing a sound in your ear that has no obvious source is unsettling. Whether it’s a rhythmic whoosh, a rapid flutter, a hollow echo when you breathe, or a pop every time you swallow, the uncertainty of not knowing what it is can quickly spiral into worry. Tinnitus is usually the first explanation people reach for — and sometimes they’re right. But tinnitus is far from the only cause of unexplained ear sounds. Many of the noises people hear have a physical, structural origin and are often treatable. This article will help you work through the possibilities, organised by what the sound actually feels like.
The Short Answer: Not All Ear Noise Is Tinnitus
Not all ear noises are tinnitus. Tinnitus is a phantom sound generated by the auditory nervous system — there is no physical source; the brain or auditory pathway produces a signal that isn’t there. Most competing causes of ear noise belong to a different category entirely: somatosounds. A somatosound is a real sound produced inside the body — by blood flow, muscle movement, or air pressure changes — that is transmitted to the inner ear and perceived as noise. Blood moving through a narrowed vessel, a muscle in the middle ear twitching, or air passing through an abnormally open Eustachian tube can all produce sounds that are physically present, not phantom. That distinction matters, because somatosounds often have an identifiable cause, and an identifiable cause can often be treated.
When It Pulses With Your Heartbeat
A whooshing, throbbing, or beating sound that rises and falls in rhythm with your heartbeat is called pulsatile tinnitus. Despite the name, it is technically a somatosound: the sound has a real physical source, most often turbulent or amplified blood flow near the ear.
Common causes include arteriosclerosis of the carotid artery (where narrowing creates turbulent flow), vascular malformations, idiopathic intracranial hypertension (IIH), sigmoid sinus dehiscence, and paraganglioma (a rare vascular tumour near the ear). Each of these has a physical correlate that can potentially be located and treated (John).
The evidence for pursuing that workup is strong. Studies show that the majority of people with pulsatile tinnitus have an identifiable cause on imaging — figures across studies range from approximately 57% at tertiary referral centres (Ubbink 2024, cited in Jairam et al. (2025)) to around 70% in broader methodological reviews (Biesinger 2013, cited in Jairam et al. (2025)). When a venous sinus stenosis is identified and treated with stenting, about 92% of patients see substantial improvement or resolution of symptoms (Schartz et al. (2024)).
Pulsatile ear sounds always warrant medical evaluation — not because they are always serious, but because a treatable cause is found in most cases. Seek prompt review rather than waiting if the pulsatile sound is accompanied by headache and visual disturbance (possible IIH), sudden hearing loss, facial weakness, or dizziness. Both the AAO-HNS clinical practice guideline and NICE guideline NG155 mandate imaging evaluation for pulsatile tinnitus.
When It Clicks, Flutters, or Taps
A rapid clicking, fluttering, or tapping sound inside the ear — sometimes in bursts, sometimes rhythmic — tends to frighten people considerably. Patients often describe the sensation as something moving inside the ear, occasionally mistaking it for an insect. In most cases, the cause is muscular or mechanical.
Middle ear myoclonus (MEM) occurs when the tiny muscles inside the middle ear — the stapedius and the tensor tympani — contract involuntarily. These spasms produce an objective clicking or low-pitched rumbling that the person can hear and, in some cases, a clinician can detect too. A systematic review of 115 patients with MEM found that the condition most commonly affects people in their late twenties and can occur at any age from childhood to older adulthood (Wong & Lee (2022)).
What makes MEM particularly interesting is the anatomy involved. The tensor tympani is innervated by the trigeminal nerve (the V3 branch) — the same nerve pathway involved in jaw clenching and bruxism. This explains why stress, teeth grinding, and jaw tension can trigger or worsen the clicking sound (Zhang-Kraczkowska & Wong (2025)). It is not tinnitus; it is a muscle doing something it shouldn’t.
TMJ disorder is a separate but related cause. The temporomandibular joint sits immediately adjacent to the ear canal, and dysfunction or grinding in that joint can produce clicking and crackling that radiates into the ear. Both MEM and TMJ-related sounds are physically real, neither involves the auditory nerve, and both are amenable to treatment — ranging from stress management and dental intervention for TMJ to medication or, in persistent MEM cases, surgical division of the middle ear tendons.
When You Hear Your Own Breathing
A blowing, hollow, or echo-like sound that moves with your breathing — or the disconcerting sensation of hearing your own voice unusually loudly inside your head — points toward a structural problem with the Eustachian tube.
The Eustachian tube normally stays closed, opening briefly when you swallow to equalise pressure between the middle ear and the back of the throat. In patulous Eustachian tube, the tube fails to stay closed between swallowing events. Instead, it remains open, transmitting the pressure changes of each breath directly into the middle ear. The result is a rhythmic blowing or rushing sound synchronised with breathing, often accompanied by autophony — the abnormal loudness of one’s own voice (Khurayzi et al. (2020)).
Commonly reported triggers include rapid weight loss, pregnancy, and Eustachian tube muscle atrophy — all conditions that reduce the tissue bulk around the tube and allow it to gape. An ENT can sometimes confirm the diagnosis by watching the eardrum move in synchrony with breathing during examination.
Patulous Eustachian tube is a structural problem, not a neurological one, and is treatable in most cases through conservative measures — including nasal saline drops — or, when needed, surgical approaches targeting the tube itself (Khurayzi et al. (2020)).
This is distinct from Eustachian tube dysfunction (ETD), where the tube is stuck closed rather than open, producing pressure, muffled hearing, and the familiar popping sensation on swallowing.
When It Pops, Crackles, or Comes and Goes
Intermittent sounds that appear with swallowing, yawning, altitude changes, or jaw movement usually have a mechanical explanation.
Eustachian tube dysfunction (ETD) is among the most common causes. The tube — which normally balances pressure between the middle ear and the external environment — becomes blocked or sluggish, often during colds, allergies, or after a flight. Pressure builds, and when it equalises through swallowing or yawning, you hear a pop or crackle. The sound is transient, often relieved by the same movements that trigger it, and typically resolves when the underlying congestion clears.
Cerumen (earwax) impaction can produce crackling or muffled sounds when hardened wax shifts inside the ear canal. This is one of the most straightforward causes to address: softening drops or a professional ear irrigation often resolves it entirely.
Stapedius muscle spasm can produce a brief, intense ringing or pressure sensation lasting a few seconds before resolving. Most people experience this occasionally — it is generally benign and self-limiting, though persistent episodes warrant evaluation.
A practical self-triage pointer: if the sound changes when you swallow, move your jaw, change posture, or yawn, that responsiveness to body movement is itself a clue that the source is mechanical rather than neurological (Healthline).
How to Tell These Apart From Tinnitus — and When to See a Doctor
Tinnitus and somatosounds feel different in ways that can help you start to orient yourself before you see a doctor.
Feature More consistent with tinnitus More consistent with a somatosound Pattern Constant or steady ringing, hissing, buzzing Rhythmic, pulsing, clicking, or blowing Triggered by movement? No — not affected by swallowing, jaw, or posture Often yes — swallowing, jaw movement, posture, breathing Synced with body functions? No Yes — heartbeat, breathing, swallowing Detectable by others? No Sometimes (in objective somatosounds) Seek prompt medical review — not a routine appointment at some distant future date, but soon — if you notice any of these:
- A pulsatile sound that beats in time with your heartbeat
- Ear sound accompanied by sudden hearing loss
- Ear sound with dizziness or vertigo
- Ear sound with facial weakness
NICE guideline NG155 and the AAO-HNS clinical practice guideline both identify pulsatile tinnitus, sudden hearing loss, and associated neurological symptoms as red-flag presentations requiring prompt evaluation and imaging.
If none of these red flags applies, that is reassuring — but any ear noise that has persisted for more than a few weeks without an obvious explanation still deserves an appointment with your GP or an ENT. The category of the sound matters enormously for what comes next.
Key Takeaways
- Not all ear noise is tinnitus. Many sounds have a physical, structural source inside the body — a category called somatosounds — and are often treatable.
- Sound that pulses with your heartbeat always warrants medical evaluation. A treatable cause is identified in the majority of cases, and some causes (such as IIH) need prompt attention.
- Clicking or fluttering sounds often point to involuntary middle ear muscle contractions or jaw joint dysfunction — not the auditory nerve. Stress and bruxism are known triggers.
- Breathing-synchronised sounds suggest a patulous Eustachian tube, where the tube stays open instead of closed — a structural, often correctable problem.
- Intermittent popping or crackling during swallowing or yawning is commonly caused by Eustachian tube dysfunction or earwax — both mechanical and very manageable.
- If the sound is constant, unrelated to movement, and has no obvious cause — that pattern is more consistent with tinnitus and also warrants evaluation.
Understanding what kind of noise you’re hearing is the first and most useful step toward getting the right help.

What Is Tinnitus? The Neuroscience Behind the Phantom Sound
That Sound No One Else Can Hear
Hearing a ringing, buzzing, or hissing that no one around you can hear is one of the more disorienting things the body can do to you. If it started suddenly — after a loud concert, a bout of illness, or apparently out of nowhere — the uncertainty can feel worse than the sound itself. Is something wrong? Is it permanent? Is this a sign of something serious?
This article will explain not just what triggers tinnitus, but why those triggers cause the brain to generate a phantom sound. Understanding the mechanism, many people find, takes some of the fear out of it.
What Causes Tinnitus: The Core Answer
Tinnitus is most commonly triggered by damage to the hair cells in the inner ear — from noise exposure, aging, certain medications, or other causes. This damage reduces the auditory signal reaching the brain. The brain responds by turning up its own internal amplifier, a process called central gain, which produces spontaneous neural activity perceived as sound even in silence. This is why tinnitus is ultimately a brain phenomenon, not just an ear problem. The ear may start the process, but the sound itself is generated in the brain’s auditory networks (Langguth et al. (2013); Henton & Tzounopoulos (2021)).
The Triggers: What Starts the Process
Several different events can reduce cochlear input enough to set off the chain of events described above.
Noise-induced hearing loss is the most common trigger. Loud sound — whether a single blast or years of occupational exposure — physically damages the hair cells in the cochlea. Once destroyed, these cells do not regenerate.
Age-related hearing loss (presbycusis) gradually reduces hair cell function across higher frequencies. Tinnitus is more prevalent in older adults for exactly this reason, though it can occur at any age.
Ototoxic medications can damage cochlear hair cells as a side effect. The most commonly implicated include high-dose aspirin and NSAIDs, certain aminoglycoside antibiotics, loop diuretics, and the chemotherapy drug cisplatin. If you have recently started a new medication and noticed tinnitus, tell your doctor.
Earwax (cerumen) blockage reduces the amount of sound reaching the cochlea, which can temporarily alter auditory processing. Tinnitus from this cause typically resolves when the blockage is cleared.
Head, neck, or jaw injuries can affect the auditory pathway or change the mechanical input to the inner ear. Temporomandibular joint (TMJ) problems fall into this category — the jaw joint sits very close to the ear canal and shares neural pathways with the auditory system.
Ménière’s disease, a condition involving fluid pressure changes in the inner ear, causes episodic tinnitus alongside vertigo and fluctuating hearing loss.
Pulsatile tinnitus deserves a separate mention. Unlike the continuous ringing or buzzing of neurogenic tinnitus, pulsatile tinnitus is rhythmic, often synchronised with the heartbeat, and usually has an actual internal sound source — typically a vascular cause such as turbulent blood flow near the ear. Pulsatile tinnitus warrants prompt medical evaluation to rule out treatable vascular conditions.
In all these cases, the trigger starts the process — but none of these peripheral events directly creates the sound you hear. That happens in the brain.
The trigger (ear damage, blockage, medication) starts the chain of events. The phantom sound itself is generated by the brain’s auditory networks in response to reduced cochlear input.
How the Brain Generates the Phantom Sound
To understand why reduced cochlear input causes a phantom sound, three interconnected mechanisms are worth knowing about.
Central gain: turning up a radio with no signal
Imagine a radio receiver that keeps amplifying its circuits when the broadcast signal gets weak — eventually the amplification itself produces audible static. The brain does something similar. When cochlear hair cells stop sending their normal electrical signals, auditory neurons that have lost their usual input begin firing spontaneously at higher rates. The brain treats this increased neural activity as if it were a real sound signal (Langguth et al. (2013)). A comprehensive 2021 review in Physiological Reviews confirmed that this central gain increase — the brain’s attempt to compensate for missing peripheral input — is one of the primary mechanisms initiating tinnitus (Henton & Tzounopoulos (2021)).
Tonotopic map reorganisation: the neighbourhood expands
The auditory cortex is organised like a piano keyboard: different regions process different frequencies, and adjacent frequency zones sit next to each other on the cortical surface. When hair cells tuned to a particular frequency are damaged and go quiet, the cortical region that processed that frequency loses its normal input. Over time, neighbouring neurons — those tuned to adjacent frequencies — begin to colonise the silent zone. This reorganisation of the cortical frequency map correlates with tinnitus severity (Eggermont (2015)). In plain terms: the brain’s internal map of sound gets redrawn around the damaged region, and the redrawn boundary is where the phantom tone lives.
Loss of lateral inhibition: the brake fails
Normally, inhibitory circuits — neurons that use the neurotransmitter GABA — act as a brake on spontaneous neural activity. They suppress background firing so that only genuine, meaningful signals get through. When cochlear input is lost, these GABAergic inhibitory circuits become less effective. Without adequate inhibition, large populations of auditory neurons fire synchronously, generating a coherent, organised neural signal that the brain interprets as a specific tone or noise rather than diffuse neural static (Langguth et al. (2013); Henton & Tzounopoulos (2021)).
Animal studies offer a striking illustration of this mechanism. Research by Galazyuk and colleagues showed that enhancing GABAergic inhibition with a pharmacological agent completely and reversibly eliminated tinnitus-like behaviour, while removing the drug caused it to return. This is consistent with the idea that inhibitory circuit failure is a proximate cause of the phantom percept, not merely a side effect of central gain.
One of the clearest pieces of evidence that tinnitus is brain-generated rather than ear-generated comes from a clinical observation: sectioning the auditory nerve — physically cutting the connection between the cochlea and the brain — does not reliably eliminate chronic tinnitus. In some cases it makes it worse. Once the brain has reorganised around the phantom signal, the signal continues even without any peripheral input at all.
Many people find it reassuring to know that their tinnitus is a real, neurologically generated experience — not something they are imagining, not a sign that their brain is malfunctioning in a dangerous way. The same neural plasticity that creates tinnitus is also what makes the brain amenable to retraining.
Why the Limbic System Decides How Bad It Feels
Here is something counterintuitive: the measured loudness of tinnitus — how loud it registers on audiological testing — is a poor predictor of how distressed a person will be by it. Many people with objectively loud tinnitus are barely bothered by it; others with faint tinnitus are significantly affected. The difference lies not in the auditory signal itself, but in how the brain evaluates it.
The limbic system, including the amygdala and connected structures in the prefrontal cortex, assigns emotional weight to sensory signals. When tinnitus is first perceived, these structures evaluate whether the signal represents a threat. If the brain classifies the phantom sound as threatening or significant, it locks attentional and emotional resources onto it — making it harder to ignore and, perceptually, louder.
Research on the neural correlates of tinnitus distress has identified measurable changes in the ventromedial prefrontal cortex (vmPFC) and nucleus accumbens — structures that normally suppress signals that have been evaluated as non-threatening — in people with chronic, distressing tinnitus. Where these suppression systems work well, tinnitus fades into the background. Where they are less effective, the phantom signal stays foregrounded in awareness (Galazyuk et al. (2012)).
This is also why stress and fatigue reliably worsen perceived tinnitus severity. Neither stress nor tiredness changes the underlying neural signal — but both reduce the brain’s capacity to suppress unwanted input, so the same signal feels louder and more intrusive.
This limbic model has a practical implication: it explains why cognitive behavioural therapy (CBT) works for tinnitus without changing the sound at all. CBT does not reduce the phantom signal — it retrains the brain’s emotional and attentional response to it, reducing the distress that amplifies the experience.
Why Some People With Hearing Loss Get Tinnitus and Others Don’t
Central gain occurs in most people with cochlear damage — so why does tinnitus develop in some and not others? This is a question the research has not fully answered, and it is worth being honest about that.
The NICE clinical guideline notes that 20–30% of people with tinnitus have clinically normal audiometric hearing (NICE (2020)). This suggests that measurable hair cell damage is not always a prerequisite — or that standard hearing tests miss more subtle forms of cochlear dysfunction.
The most compelling current explanation focuses on the integrity of inhibitory circuits. Research by Knipper and colleagues proposes that the key differentiator is not how much central gain increases after hearing loss, but whether GABAergic inhibitory circuits remain intact enough to prevent that gain from generating a coherent phantom signal (Knipper et al. (2020)). Under this model, people whose inhibitory circuits hold up after cochlear damage do not develop tinnitus, even if their central gain has increased.
A complementary theoretical framework — predictive coding — suggests that tinnitus represents the brain making its best guess about missing sensory input, with individual differences in how the brain weighs top-down predictions against bottom-up signals helping to explain why outcomes vary so widely. Both the gain and prediction-based explanations are plausible; neither fully accounts for the observed individual variability (Schilling et al. (2023)).
Possibly genetic factors also affect inhibitory circuit resilience, but specific genetic evidence in humans remains limited. The science is honest about this gap.
If you have noticed new tinnitus — particularly if it is in one ear only, accompanies sudden hearing loss, or has a pulsatile rhythm matching your heartbeat — see a doctor promptly. These patterns can indicate causes that benefit from early assessment.
Key Takeaways
- Tinnitus is most commonly triggered by cochlear hair cell damage from noise, aging, medications, or other causes — but the peripheral trigger only starts the process.
- The sound itself is generated by the brain, through central gain amplification, tonotopic map reorganisation, and the breakdown of inhibitory (GABAergic) circuits that normally suppress spontaneous neural firing.
- Limbic and prefrontal structures determine how distressing tinnitus is — which is why identical acoustic signals cause minor background noise for some people and significant daily disruption for others.
- The fact that tinnitus is brain-generated is not a reason for despair: it is precisely why brain-targeted approaches — sound therapy, CBT, and emerging neuromodulation techniques — can make a real difference.
- If you have noticed new tinnitus, an early ENT evaluation is worthwhile; the acute phase, before central reorganisation becomes entrenched, offers the best chance of resolution or significant improvement.
