Sound Therapy for Tinnitus: How Masking and Relaxation Work

What is sound therapy for tinnitus?

Sound therapy is the use of external sounds to reduce the perception of tinnitus or the distress it causes. It is based on the principle that a quiet environment makes tinnitus more noticeable, while a richer sound environment gives the brain more to process, reducing the relative salience of the internal sound. Sound therapy does not typically eliminate tinnitus, but it can make it far less intrusive — especially during sleep and relaxation.

Masking: covering the tinnitus

Masking is the most straightforward form of sound therapy. The idea is to play an external sound at a volume that partially or completely covers the tinnitus, so it is less audible. Complete masking (where you cannot hear the tinnitus at all) is not always necessary or desirable — partial masking, where the tinnitus is present but blended with other sound, is often sufficient and more comfortable for extended use.

White noise

White noise contains equal energy across all frequencies — a flat, even hiss that many people compare to static or rain on a window. It is particularly effective for high-frequency tinnitus because it covers that range along with all others. White noise is widely available in machines, apps, and fans, and is well-suited to sleeping because it also masks other environmental disturbances (traffic, a snoring partner).

Pink noise

Pink noise has more energy in low frequencies than high ones, giving it a warmer, deeper quality than white noise — like a gentle waterfall or rainfall. Many people find it more pleasant for extended listening. It is particularly helpful for tinnitus that has a lower-pitched character or for people who find pure white noise too harsh.

Pure tone matching

For tonal tinnitus (a single-pitch ringing), playing a pure tone at or near the tinnitus frequency can be very effective. This is the purpose of Acuhealer's Pure sound mode, which offers tones at 1 kHz, 4 kHz, and 8 kHz — the frequency ranges most commonly affected by tinnitus. To find your match, experiment with each frequency and notice which one seems to blend most naturally with your internal sound.

Notch therapy

Notch therapy is a specialized form of sound therapy where the exact frequency of the tinnitus is identified (through pitch matching) and then a "notch" — a dip in volume at that exact frequency — is applied to music or broadband noise. The theory is that reducing stimulation at the tinnitus frequency may reduce neural hyperactivity in that region over time. Research results are promising but still emerging; it is best delivered through an audiologist who can precisely match your tinnitus frequency.

Nature sounds and music

Many people find relief through gentle nature recordings (rainfall, ocean waves, birdsong, forest sounds) or soft instrumental music. These sounds are psychologically soothing and provide auditory enrichment without being distracting. Music should be played at a comfortable volume that does not require you to consciously listen — background, not foreground.

How to use sound therapy effectively

• Use it consistently — especially at night and during quiet, stressful, or unoccupied moments when tinnitus tends to feel most intrusive.
• Keep the volume comfortable — it should blend with or partially cover the tinnitus, not drown it out at a loud volume that could cause further hearing damage.
• Experiment with different sounds — what works for one person's tinnitus type and frequency may not work for another's.
• Use a sleep timer — falling asleep to sound therapy and having it switch off automatically prevents all-night playback that may interfere with deeper sleep stages.
