Frequency discrimination in forward and backward masking.
Frequency difference limens for pure tones preceded by a forward masker or followed by a backward masker were obtained across a wide range of signal levels. Relkin and Doucet [Hear. Res. 55, 215-222 (1991)] have shown that at a masker-signal delay of 100 ms, the thresholds of high-SR (spontaneous rate) auditory-nerve fibers are recovered, while the low-SR fiber thresholds are not. Therefore, fo...
متن کاملTheme 1: Masking and Frequency Selectivity
The main theme in this topic area is to highlight the different approaches taken by hearing scientists to characterize the human auditory system. If our auditory system behaves like a linear time-invariant system, whereby the response of the cochlear filter is completely described by the relationship between its inputs and its outputs, such characterization would be a trivial matter. However, o...
متن کاملPrecursor effects on behavioral estimates of frequency selectivity and gain in forward masking.
The experiments presented in this paper explore the hypothesis that cochlear gain is reduced, in a frequency-specific manner, over the course of a sound (called a "precursor") which was designed to activate the medial olivo-cochlear reflex (MOCR). Psychophysical tuning curves (PTCs) and off-frequency growth of masking (GOM) functions were measured with two precursors. The on-frequency precursor...
متن کاملPsychophysical tuning curves measured in simultaneous and forward masking.
The level of a masker necessary to mask a probe fixed in frequency and level was determined as a function of masker frequency using a two-interval forced-choice technique. Both simultaneous- and forward- masking techniques were used. Parameters investigated include the level of the probe tone and the frequency of the probe tone. The general form of the psychophysical tuning curves obtained in t...
متن کاملInteractions of forward and simultaneous masking in intensity discrimination.
Intensity coding mechanisms are explored in a paradigm involving both forward and simultaneous masking. For intensity discrimination of 1000-Hz pure tone in quiet, a near-miss to Weber's law is observed. However, as more stimulus components are added to this relatively simple experiment, interactions among components produce a more complex pattern of results. An intense forward masker, while no...
