The spectral spread of the loudness reduction for tones that decrease continuously in level over time is studied. A peripherally based mechanism should produce a narrow region of adaptation consistent with the frequency analyzing properties of the cochlea. Ten subjects listened to tones produced by a function generator using headphones. Each subject served for two to two and a half hours, and their tests were completed during a single session. The response region was revealed using a delayed matching procedure.
