Notched Sound Therapy for Tinnitus: How It Works (2026)
Most guides to sleep sounds for tinnitus start and end with masking: play a steady noise softly so the ringing stops standing out. Notched sound therapy takes a different angle. Instead of covering your tinnitus, it removes a slice of sound right where your tinnitus sits, aiming to gently retrain how much attention your brain gives that pitch. This pillar explains what notched (and low-intensity) sound therapy is, how it compares to masking and habituation, what the 2025 evidence actually says, and how to try a notched masker in Momental.
What is notched sound therapy for tinnitus?
Notched sound therapy is a form of low-intensity sound therapy that starts from your own tinnitus pitch. An audio signal - broadband noise or music - has a narrow band of frequencies removed, or "notched out," right around the frequency of your ringing. Everything except that slice plays as normal; the slice at your tinnitus pitch is left silent.
You will also see it called notched music therapy (when the notch is applied to your favorite music) or tailored, low-intensity sound therapy. The common thread is personalization: the sound is shaped around the specific frequency you hear, rather than being a one-size-fits-all hiss.
The reasoning is based on how the hearing system reinforces itself. Neurons tuned to neighboring frequencies can quiet the neurons at the notch - an effect researchers describe as lateral inhibition. The theory is that, played regularly over weeks, a notch at your tinnitus frequency gives the brain less reinforcement at that exact pitch, so it gradually gives the ringing less attention. It is a slow, retraining-style idea, not an instant off switch.
Notched therapy vs plain broadband masking
Plain masking and notched therapy solve different halves of the problem.
Masking is immediate and about comfort. A steady sound - white, pink, brown, green, or rain - sits over the ringing so the contrast between your tinnitus and a silent room shrinks, and your brain stops latching onto it. That is exactly what you want at 11pm when you cannot sleep. It works from the first minute and asks nothing of you except a volume dial.
Notched therapy is slower and about attention. Because the band at your tinnitus pitch is removed rather than covered, notched audio is not trying to drown the ringing out tonight - it is trying to change how much the brain focuses on that frequency over weeks of listening. That makes it a routine, not a rescue. In practice, many people use both: masking to fall asleep now, and a notched or tuned session earlier in the evening.
Masking vs notched therapy vs habituation (TRT)
Sound-based approaches to tinnitus sit on a spectrum from pure comfort to structured retraining. Here is how the three most common ones compare.
| Approach | How it works | Best when | Evidence status |
|---|---|---|---|
| Broadband masking | A steady noise (white, pink, brown, rain) softly covers the ringing to lower its contrast with a quiet room | You want fast, simple relief at bedtime | Long-standing comfort tool used by audiologists |
| Notched sound therapy | Audio with a narrow band removed around your tinnitus pitch, so the brain gets less reinforcement there over weeks | You know your pitch and want a longer-term routine | Emerging as of 2025; outcomes vary between people |
| Habituation (TRT) | Low-level background sound plus counseling to help the brain reclassify tinnitus as unimportant | You want a structured, clinician-guided program | Established framework, delivered by audiologists |
None of these makes tinnitus disappear. They are ways to make it quieter in your attention, help you rest, and - in the notched and habituation cases - encourage the brain to care less about the sound over time.
What the 2025 evidence says
Notched and low-intensity sound therapy is the emerging 2025 direction in tinnitus sound work, but the evidence is still early and mixed. Reported in 2025 clinical coverage, a growing number of audiology practices are exploring individually tuned, low-intensity sound rather than blanket masking. Northeast Occupational Audiology (2025) describes low-intensity, personalized sound therapy as a developing approach that aims to reduce how much attention the brain gives the tinnitus frequency, while noting it is not a guaranteed outcome for everyone.
On the research side, a 2025 randomized controlled trial summarized in the International Tinnitus Journal reported that notched sound routines helped some participants perceive their tinnitus as less intrusive compared with a control condition. The authors were careful: the effects were modest, they did not hold for every listener, and they stressed that larger studies are still needed. The honest reading of 2025 is that notched therapy is promising and worth trying, not proven, and results vary from person to person.
Notched and masking modes in Momental
Momental brings both approaches into one Tinnitus Masking section on the home screen. It starts with a pitch-match test tone: you slide a tone across roughly 2,000 to 12,000 Hz until it lines up with your ringing, and the app centers a notched masker around that pitch so the band you actually hear is eased back. If you prefer plain masking, you can layer colored noise - white, pink, brown, or green - with Rain, Ocean, or Fan mixes, or start the ready-made Tinnitus Relief blend in one tap.
During onboarding you can choose the Manage Tinnitus goal so Momental tunes suggestions toward masking, and every session has a sleep timer for timed or all-night play. If you are new to finding your pitch, follow our step-by-step guide to matching your tinnitus frequency. It is one-tap simple, no talking, free to try, and works on iOS and Android.

When to see a doctor about tinnitus
Sound routines manage how tinnitus feels; they do not diagnose what is behind it. See an audiologist, ENT, or doctor if your tinnitus is new, sudden, in one ear only, or pulsatile (beating in time with your heartbeat), or if it comes with hearing loss, dizziness, or ear pain. Also seek help if the ringing appears after loud-noise exposure or a head injury, or if masking and good sleep habits bring no relief after a few weeks.
Frequently Asked Questions
What is notched sound therapy for tinnitus?
It is a personalized form of sound therapy that removes a narrow band of frequencies around your own tinnitus pitch from broadband noise or music. The rest of the sound plays normally. Over weeks of listening, the notch is meant to give your brain less reinforcement at that pitch so it gives the ringing less attention. It is a routine, not an instant off switch.
Is notched sound therapy better than masking?
They do different jobs. Masking covers the ringing for immediate comfort and better sleep tonight, while notched therapy tries to shift attention away from your tinnitus frequency over weeks. Many people use masking to fall asleep and a notched or tuned session earlier in the evening. As of 2025 the evidence for notched therapy is emerging, not settled.
Does notched sound therapy work? What does the 2025 evidence say?
Results vary. Northeast Occupational Audiology (2025) describes low-intensity, tuned sound as a promising emerging approach, and a 2025 randomized controlled trial summarized in the International Tinnitus Journal found some listeners perceived their tinnitus as less intrusive - but the effects were modest and did not apply to everyone. It is worth trying, not a guaranteed outcome, and never a replacement for medical care.
Do I need to know my tinnitus pitch to use notched therapy?
Yes, roughly. Notched therapy is built around your specific frequency, so you first match a tone to your ringing. In Momental you can do this with the pitch-match test tone across about 2,000 to 12,000 Hz. If you are not sure where to start, see our guide to matching your tinnitus frequency.
How long until notched sound therapy helps?
Think in weeks, not minutes. Because notched therapy works by gradually changing how much attention your brain gives your tinnitus pitch, most approaches are used daily over several weeks. If you need relief tonight, use plain masking alongside it. If nothing improves after a few weeks, check in with an audiologist.
