What is residual inhibition?
Residual inhibition is the temporary suppression of tinnitus after someone who uses a masker turns the masker off. Sometimes, someone may have a masker in, wear it for a little while, and then turn it off to find out that his tinnitus is either reduced or totally absent. The time period of this cessation of tinnitus after masking can vary from a few minutes to a few days. People who experience residual inhibition must have tinnitus that can be masked — i.e., a masker must be a viable treatment for your tinnitus.
