Here's How it Works:
Tinnitus often varies in pitch and intensity. For some, listening to a high-pitched tone like 7500 Hz can temporarily change their tinnitus perception. This could be due to two interesting effects: Relief Contrast and Residual Inhibition.

Relief Contrast:

When you hear a 7500 Hz tone—close to the pitch of your tinnitus—it can “blend” with the ringing, making it feel less intense and providing temporary relief. However, once the tone stops, you may notice your tinnitus sounds louder or shifts in pitch. This effect usually lasts only a few seconds to minutes and occurs when there is no longer a contrasting sound for the brain to focus on.

Residual Inhibition:

In this case, the 7500 Hz tone can momentarily block out your tinnitus, providing a short-lived sense of quiet. The tone temporarily stops or inhibits your perception of the tinnitus because of its stimulation close to your tinnitus match.This relief is also temporary, typically fading shortly after the tone stops.

Both of these effects indicate neuroplasticity, showing that the brain can change its tinnitus perception, which is a positive sign that sound therapy could help reduce tinnitus awareness.
