}The purpose of this study was to compare detection of increments and decrements occurring over limited regions of time and frequency within a 500-ms broadband (0-6000 Hz) noise. Three listeners tracked detection thresholds adaptively in a two-interval, two-alternative forced-choice task. Thresholds were measured for both increments and decrements in level [delta L = 10 log10(1 + delta N0/N0) dB, where N0 is the spectral power density of the noise] as a function of signal duration (T = 30-500 ms…

Overall the results suggest that, in the absence of cues in the audio-frequency domain, rapid changes in envelope contribute little to near-threshold increment or decrement detection.

Evidence is presented that indicates detection of absolute energy is not necessary for the TI effect and the frequency dependence of TI is consistent with variations across frequency in peripheral auditory tuning, rather than the integration process per se.
Detection of high-frequency spectral notches as a function of level.

The threshold notch depth necessary to discriminate between a flat spectrum broadband noise and a similar noise with a spectral notch centered at 8 kHz was measured and the importance of the onset rate-profile representation of the notch was estimated by varying the stimulus duration and its rise time.

High-frequency spectral notches are important cues for sound localization. Our ability to detect them must depend on their representation as auditory nerve (AN) rate profiles. Because of the low…

The quadratic-compression model described by Neely and Jesteadt provided a better approximation to the data than a model based on excitation patterns and was altered less by a noise band above the pedestal/increment frequency than by a broadband noise that produced equal masking at the pedestals of equal sensation level.

The results suggest that decision processes involved in both forward masking and increment detection are similar and that neither is based on energy detection.

The findings suggest that overshoot in normal and hearing-impaired listeners is mediated by some form of dynamic range adaptation other than what is observed in the auditory nerve of anesthetized animals.

Data from two experiments are interpreted as being consistent with previous suggestions that the aging process results in a decline in auditory memory capacity and/or internally generated selective attention.

The ability to make intensity judgments for sequential stimuli was examined with an intensity-discrimination task involving three 50-ms noise bursts with non-overlapping frequency ranges, indicating a specific intensity-processing deficit for stimuli occurring later in a sequence.

The results did not follow the prediction of a constant bandwidth-duration (WT) product, but may be understood in terms of cues available to the listener from the relative combination of signal and masker parameters.

It is suggested that the results for decrement detection may be affected by neural long-term adaptation, although they are not clearly related to loudness adaptation.

Thresholds for decrements, in terms of the dB change in level (delta L), were found to be more dependent on duration than those for increments, which is consistent with the predictions of the temporal-window model or other similar models of temporal resolution.

A comparison of observer performance relative to the statistical limits imposed by the roving-level procedure indicated that the traditional critical-band energy-detector model could not account for the results, which are attributed to discrimination based on spectral shape or on waveshape.
