We then use Real Ear Measurement (REM) to verify that the devices are delivering the amplification that you need.

Tinnitus can vary in severity and even though most people have a relatively mild form, it can have a big impact on their quality of life. These signals might then become over-represented in the brain which may cause the sounds of tinnitus.
