采用21FC程序，研究了听力受损者和正常听者在噪声环境下的听觉时间加工。首先，在500、1500、2000和4000 Hz频率下，测量了3 ~ 985毫秒的宽频带噪声时间积分函数。其次，在连续窄带（400-800 Hz）噪声掩蔽器存在的情况下，测量了500 - 4000 Hz六个频率下5毫秒和146毫秒信号的可探测性。最后，研究了5毫秒1500 Hz信号和窄带（400-800）噪声掩蔽器的前向掩蔽、后向掩蔽和间隙掩蔽。对于间隙掩蔽，掩蔽是连续的，除了在每个观察间隔中有短暂的沉默或持续时间为20毫秒、50毫秒或200毫秒的“间隙”。从这些数据中可以看出几个总的趋势。首先，当听力损失大于40分贝时，所有听力受损受试者的时间整合表现都比正常人差。第二，噪音听力损失的听众…
A variety of tasks, using a 21FC procedure, were employed to investigate auditory temporal processing in noise by hearing‐impaired and normal listeners. First, temporal integration functions were measured in wide‐band noise for tonal durations ranging from 3 to 985 msec at 500, 1500, 2000, and 4000 Hz. Second, detectability in the presence of a continuous narrowband (400–800 Hz) noise masker was measured for 5‐ and 146‐msec tonal signals at six frequencies from 500 to 4000 Hz. Finally, forward masking, backward masking, and gap masking were studied for a 5‐msec 1500‐Hz signal and a narrow‐band (400–800) noise masker. For gap masking, the masker was continuous except for a brief silence or “gap” of 20‐, 50‐, or 200‐msec duration during each observation interval. Several general trends emerged from the data. First, all hearing‐impaired subjects showed poorer than normal temporal integration at frequencies where their audiometric loss was greater than 40 dB. Second, listeners with noise‐induced hearing loss ...
