Characterizing the nature and severity of tinnitus in individuals presents a particular challenge. The nature of the sound (loudness and pitch) is not necessarily indicative of the effect on quality of life. Different methods are used to measure each parameter. Loudness is measured using a technique called "minimum masking," in which the subject is presented with a broadband white noise and asked to adjust the loudness level until they can no longer hear their tinnitus. Severity of tinnitus is commonly characterized using two questionnaires: the Tinnitus Handicap Inventory (THI) and the Tinnitus Functional Index (TFI). These questionnaires assess the perceived severity of the tinnitus and the effect on everyday activities and quality of life. A visual analog scale (a scale from 0-10) is used as a general subjective measurement of tinnitus severity. In the first part of this study, we will measure each of these parameters over a series of sessions to establish a baseline variability for each individual.
