Extract

Regardless of the procedure used for the treatment of tinnitus, most clinicians initially attempt to determine the pitch and loudness of tinnitus. If the treatment of choice is a tinnitus masking program, two additional measures are made routinely. The first is an evaluation of the minimum masking level (MML) and the second is a determination of the amount of residual inhibition that occurs as the result of presenting a continuous stimulus over a period of time (generally for one minute).
