Software for psychoacoustic testing. A) VAS for tinnitus intensity. Scale bar = 9cm on tablet screen. B) Loudness discomfort levels are reported for pure tones (125Hz-8000Hz, presented in a random order) by adjusting the virtual slider until loudness first becomes uncomfortable. C) Participants adjust the frequency, level, modulation rate and bandwidth of a continuous sound that matches their tinnitus as closely as possible. Slider starting point and dynamic range are varied between trials. D) Subjects are then asked to rate the resemblance of this sound to their tinnitus percept.
