“…This second prediction is extremely well documented for unmasked ͑absolute͒ thresholds ͑e.g., Miskolczy-Fodor, 1953;Elliott, 1963;Wright, 1968;Pedersen and Elberling, 1973;Chung, 1981;Florentine et al, 1988͒: There is indeed in general a reduction in the slope of the temporal-integration function for listeners with sensorineural hearing loss. This is not due to the generally higher levels at which the stimuli are presented to the hearing-impaired listeners ͑Gengel, 1972; Florentine et al, 1988͒ and cannot be accounted for by the possible detection of spectral splatter ͑Florentine et Carlyon et al, 1990͒.…”

Thresholds for a 6.5-kHz sinusoidal signal, temporally centered in a 400-ms broadband-noise masker, were measured as a function of signal duration for normally hearing listeners and listeners with cochlear hearing loss over a range of masker levels. For the normally hearing listeners, the slope of the function relating signal threshold to signal duration ͑integration function͒ was steeper at medium masker levels than at low or high levels by a factor of nearly 2, for signal durations between 2 and 10 ms, while no significant effect of level was found for signal durations of 20 ms and more. No effect of stimulus level was found for the hearing-impaired listeners at any signal duration. For signal durations greater than 10 ms, consistent with many previous studies, the slope of the integration function was shallower for the hearing-impaired listeners than for the normally hearing listeners. However, for shorter durations, there was no significant difference in slope between the results from the hearing-impaired listeners and those from the normally hearing listeners in the high-and low-level masker conditions. A model incorporating a compressive nonlinearity, representing the effect of basilar-membrane ͑BM͒ compression, and a short-term temporal integrator, postulated to be a more central process, can account well for changes in the short-term integration function with level, if it is assumed that the compression is greater at medium levels than at low or high levels by a factor of about 4. This is in reasonable agreement with physiological measurements of BM compression, and with previous psychophysical estimates.

“…Threshold-duration functions have also been examined in pathological ears, particularly those with cochlear hearing losses. Miskolczy-Fodor (1954) and Harris, Haines and Myers (l9Se) observed deviant T-D functions with pure tone signals for various types of cochlear disorders. Wright (1968a) reported that measurements of T-D functions were more sensitive to physiologic disturbances at the 2 level of the cochlea than were measures of loudness recruit ment.…”

The purpose.of this investigation was to compare the effects of temporal auditory integration on the acoustic reflex thresholds for subjects with normal hearing and for subjects with noise-induced permanent threshold shift. Threshold-duration functions were determined for 1, 2,.and 4 KHz pure tones and for broad-band noise. Acoustic reflexes were monitored using an impedance technique. Stimulus durations employed were 20, SO, 100, .200, and 500 msec. A measurement technique was developed which included observation of the impedance bridge output deflections in conjunction with latency time to confirm the occurrence of reflex activity. Res ults of the study indicated that there may be flattening of acoustic reflex threshold�duration functions for persons having noise-induced hearing los se�� Flattened functions appeared to be frequency specific and corresponded to areas of hearing los s. The degree of flattening of the functions was related to the degree of the hearing los s, with flatter functions occurring for greater hearing losses. ii �197693

“…Threshold is established by a psychophysical tracking method for stimuli of various durations 1 msec to 1 sec. At levels near threshold and for durations up to 200 msec, an increase in duration by a factor of 10 results in a decrease of threshold by about 10 dB (Garner and Miller, 1947;Miskolczy-Fodor, 1953;Harris et al, 1958). This summation of energy is attributed to the central nervous system rather than peripheral processes (Zwislocki, 1969).…”
