The present study was conducted as part of a continuing investigation of the influence of control ear stimulation on the amount of loudness adaptation. Perstimuiatory loudness adaptation at 1000 Hz was assessed for six normal-hearing subjects via single simultaneous dichotic loudness balances using the method of constant stimulus differences. The amount of adaptation was determined as a function of the duration of the comparison signal for two levels (50 and 80 dB SPL) and two durations (8 and 12 sec) of the adapting signal. The duration of the comparison signal ranged from 0.2 to either 6 or 8 sec. An apparent increase in the amount of adaptation occurred as the duration of the comparison signal was increased. The magnitude of this increase and the shape of the function relating the amount of adaptation to comparison signal duration differed for the two adapting durations employed, but was relatively independent of the intensity level of the adapting signal.
