Tinnitus masker

A tinnitus masker is an electronic device that makes a quiet sound. It is used by people with tinnitus to cover up ringing or other sounds they hear. Many people who have tinnitus also have hearing loss. This means they cannot use a hearing aid that also acts as a tinnitus masker. Many times, tinnitus maskers need to be customised by an audiologist. This is to make sure the sound it makes can stop the person from hearing their tinnitus.

 Functionality 
Sounds from tinnitus are heard differently by everyone. It can be occasional or constant. It can also come as different sounds, and be loud or quiet. How loud it is (the sensation level) compared to other noise in the environment is an important factor when setting the sound generator. The level of noise produced by a sound generator depends on the sensation level of tinnitus experienced and can be close to this level of this noise or even louder. The purpose of this is to cover up the tinnitus sounds by having a constant noise playing in the background. Noise produced by a tinnitus masker, which is called white noise, is designed to be calming and less irritating than tinnitus sounds. Tinnitus maskers are not actually eliminating tinnitus or reducing it but provide a distraction to cover it up for those experiencing it. 

The idea behind tinnitus maskers can be explained by a light analogy. While turning on a lamp in a dark room will be very noticeable and the change in lighting will be very obvious, the change from turning a lamp on in a room that is already lit will not be very obvious. The change would have been masked by the other light that was already present in the room.
