What Is a Tinnitus Masker?
A tinnitus masker is a device or app that generates external sound to reduce the perceived contrast between silence and the ringing, buzzing, or hissing you hear. The term is actually an umbrella covering two distinct therapeutic approaches: complete masking, which raises the external sound until the tinnitus disappears from awareness, and sound enrichment, which keeps the external sound just audible alongside the tinnitus to encourage the brain to habituate over time. Knowing which approach you are using (and why) changes how you set your device and what results you can realistically expect.
A tinnitus masker generates external sound to reduce the contrast between silence and the tinnitus signal. For long-term habituation, the sound should be set at the “blending point”: just loud enough to be heard alongside the tinnitus, not loud enough to cover it completely.
Why Sound Can Quiet the Tinnitus Signal — The Science in Plain Language
Wanting relief from tinnitus is completely understandable, and the fact that sound can help is not a placebo trick. There is a genuine neurological reason it works.
Tinnitus tends to feel loudest in quiet environments. When the brain receives less external sound input, it compensates by turning up its own internal sensitivity, a process called central gain. The phantom sound you hear becomes more salient not necessarily because it has gotten louder, but because the contrast between it and the surrounding environment has increased. Introducing a background sound reduces that contrast, making the tinnitus less noticeable without doing anything to the tinnitus signal itself.
There is also a phenomenon called residual inhibition: after you stop using a masking sound, tinnitus perception is sometimes temporarily reduced or absent. This effect can last from seconds to a few minutes and varies widely between people. Researchers do not fully understand the mechanism, but it suggests that external sound can temporarily reorganise how the auditory system processes internal signals.
The American Tinnitus Association notes that the brain cannot concentrate equally on two competing stimuli at once (American Tinnitus Association). When a background sound is present, the tinnitus signal receives less attentional weight. This is why even a modest background sound (running water, a fan, a nature recording) can shift your perception significantly in a noisy day-to-day environment but seem to have little effect at night when everything else is silent.
Complete Masking vs. Sound Enrichment: Two Goals, Two Settings
Here is the distinction that most device guides skip, and it is the one most likely to affect whether sound therapy actually helps you.
Complete masking (associated with the work of Jack Vernon in the 1970s) means raising the external sound volume until the tinnitus is no longer audible. The goal is immediate relief: the sound covers your tinnitus the way a conversation covers background noise in a restaurant. This works well in the moment. For a difficult evening, a stressful meeting, or a night when sleep feels impossible, turning the volume up is a legitimate short-term strategy.
The problem is that complete masking does not encourage the brain to learn to ignore the tinnitus signal. Because you are never hearing the two sounds together, the brain has no opportunity to reclassify tinnitus as unimportant background noise.
Sound enrichment at the blending point (the approach used in Tinnitus Retraining Therapy, developed by Pawel Jastreboff) works differently. The aim is to set the background sound just low enough that both the external sound and your tinnitus remain audible at the same time. Clinically, this is called the mixing point or blending point. Patients in TRT protocols are explicitly “encouraged not to mask or cover the tinnitus” (Henry, 2021). At this setting, the brain gradually learns to treat the tinnitus signal as a neutral background sound, and over months, it becomes less attention-grabbing.
A useful analogy: imagine learning to ignore a clock ticking in your office. If someone plays loud music every time you sit down, you never learn to tune it out. But if you add just enough background sound that the tick is softer in context, your brain can start deprioritising it.
The practical implication: if you want short-term relief right now, a higher volume is appropriate. If your goal is long-term habituation, keep the volume lower than your instinct says. This is one of the main reasons audiologist guidance on device settings matters. Most people naturally reach for a higher volume, which feels better immediately but may slow the habituation process.
TRT guidelines specify that sound generators should be “set below the mixing point” and that “in theory, sound therapy alone cannot affect the goal of habituation” (Henry, 2021). Habituation requires sound enrichment combined with counselling, not sound alone.
Types of Tinnitus Maskers: Which Format Fits Your Life?
There are four main categories of sound therapy device. Each has a different use case, cost tier, and level of clinical involvement.
Bedside and tabletop white noise machines
These are standalone speakers that play white noise, pink noise, or nature sounds at low volume throughout the night. They are the lowest-cost, lowest-commitment option: no fitting required, no audiologist visit. For people whose tinnitus mainly disrupts sleep, a bedside machine is often the first thing worth trying. Cost typically runs from £20 to £100. The main limitation is that they only help when you are stationary at home.
Smartphone apps
Apps offer the widest variety of sounds and the most flexibility. You can test dozens of sound types, adjust frequency balance, and set timers, all at no cost or very low cost. Apps are an excellent starting point before investing in hardware, because they let you find out whether sound therapy is likely to help you and which sounds you personally find least attention-grabbing. The drawback is that wearing earphones all day is uncomfortable, and screen dependency can itself become disruptive at night.
Wearable in-ear and behind-the-ear (BTE) sound generators
These look similar to hearing aids and are worn during waking hours. Sometimes called tinnitus noise generators, they deliver a continuous low-level sound directly into the ear canal and are the device type most commonly used in TRT protocols. Because they require professional fitting and calibration, they offer the most precise blending-point settings. Cost ranges from several hundred to over £1,000 for privately purchased devices. An audiologist sets the sound level relative to your specific tinnitus pitch and loudness. These are the best choice for people who need consistent relief across all daily environments.
Combination hearing aids with built-in masking features
Around 90% of people with chronic tinnitus also have some degree of hearing loss (American Tinnitus Association). For these individuals, a combination device that both amplifies environmental sound and delivers a masking or enrichment signal is often the most practical option. Hearing aids address tinnitus through several mechanisms: masking, increased auditory stimulation from the environment, and improved communication (American Tinnitus Association). Many patients find that simply correcting their hearing loss reduces tinnitus prominence on its own, with the masking feature as an additional tool. Combination devices require an audiological assessment and hearing test.
Which Sounds Work Best? White Noise, Pink Noise, Nature Sounds, and Beyond
Most people starting sound therapy immediately ask: which sound is best? The honest answer is that research does not clearly favour any single sound type.
A 2025 feasibility study found no clinically meaningful difference in tinnitus distress outcomes between white noise and enriched acoustic environment (a broader mixture of natural sounds) over four months of use (Fernández-Ledesma et al., 2025). White noise showed slightly higher average score improvements on validated questionnaires, but the authors attributed this to higher baseline severity in the white noise group, not inherent superiority of the sound. Adherence was actually higher in the enriched acoustic environment group (particularly the personalised therapy arm).
A separate study found that amplitude-modulated tones (called S-Tones, sounds that vary in volume at a set rate) calibrated to a patient’s specific tinnitus pitch reduced short-term loudness by approximately 28% among those who responded to masking, compared with around 15% for broadband white noise (Tyler et al., 2014). This suggests some modest advantage for personalised sounds, though the study measured only immediate (120-second) effects, not long-term outcomes. Around a third of participants showed no significant response to any masker type.
Notched music therapy, in which the frequency band corresponding to a patient’s tinnitus pitch is filtered out of music, is another approach with early evidence of benefit through proposed changes in how the brain’s hearing centre (auditory cortex) processes sound. This is a more specialised intervention typically provided in a clinical setting.
The practical takeaway: experiment with sounds you find genuinely unobtrusive. A sound that captures your attention competes with concentration rather than fading into the background. Patient preference and consistent use appear to be stronger predictors of benefit than sound type.
Who Is — and Isn’t — a Good Candidate for Tinnitus Masking?
Sound therapy does not suit everyone equally. Being clear-eyed about candidacy saves both money and frustration.
Good candidates include:
- People whose tinnitus can be covered or blended at a comfortable, non-straining volume
- People who need short-term relief for specific situations (sleep, focused work, stressful environments)
- People with hearing loss alongside tinnitus, who may benefit most from combination hearing aid devices
- People who are willing to use sound therapy consistently over months rather than expecting quick results
Candidates who may not benefit as much:
- People with very loud tinnitus that cannot be matched or blended without pushing the masking volume to an uncomfortable or potentially unsafe level
- People who want to use masking as a long-term avoidance strategy without any accompanying counselling (the research evidence here is cautionary: the Cochrane review of six RCTs found no significant change in tinnitus loudness or overall severity from sound therapy compared with other active interventions, and no lasting benefit beyond the period of active sound exposure was confirmed (Hobson et al., 2012))
- People who already find external sounds distressing due to hyperacusis (sound sensitivity), where standard masking volumes may worsen discomfort
The AAO-HNS guideline classifies sound therapy as an “option” rather than a standard recommendation, reflecting this limited evidence base (Tunkel et al., 2014). If you are considering a wearable sound generator, an audiological assessment before purchasing is strongly advisable.
If you are not sure whether your tinnitus can be masked at a comfortable volume, a trained audiologist can measure this during a standard tinnitus assessment. This is called a minimum masking level test and takes only a few minutes.
Getting Started: Practical Next Steps
If you are considering a tinnitus masker, a few principles apply regardless of which device you choose.
Start low-cost. A free or inexpensive smartphone app lets you test whether sound therapy reduces your tinnitus salience and which sounds you find easiest to ignore. Spending several hundred pounds on a wearable device before you know your sound preference is unnecessary.
Set the volume with intention. For day-to-day use aimed at long-term relief, keep the sound at the blending point: audible alongside your tinnitus, not covering it. For moments when you simply need to get through a difficult few hours, a higher volume is a reasonable short-term choice.
Pair sound with support. The evidence that sound therapy alone produces durable benefit is weak (Hobson et al., 2012). The research consistently shows better outcomes when sound enrichment is combined with counselling, whether through a formal programme like TRT, cognitive behavioural therapy (CBT), or audiologist-guided self-management.
Get an assessment if tinnitus is persistent. If tinnitus has been bothersome for more than a few weeks, is accompanied by hearing loss, or is significantly affecting sleep or concentration, see your GP or request a referral to an audiologist. They can rule out underlying causes and advise on the most appropriate combination of interventions for your situation.
Maskers offer real, practical relief. Used well, with realistic expectations about what they can and cannot achieve on their own, they are a genuinely useful part of tinnitus management.
