Modeling the additivity of nonsimultaneous masking.
Thresholds were measured for detecting a brief 6-kHz sinusoidal signal preceded by a broadband noise masker (forward masking), followed by the masker (backward masking), or both preceded by and followed by the masker (combined masking). The masker-signal interval was systematically varied. Consistent with the literature, thresholds in the combined-masking condition were higher than would be pre...
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 کاملAdditivity of nonsimultaneous masking for short Gaussian-shaped sinusoids.
The additivity of nonsimultaneous masking was studied using Gaussian-shaped tone pulses (referred to as Gaussians) as masker and target stimuli. Combinations of up to four temporally separated Gaussian maskers with an equivalent rectangular bandwidth of 600 Hz and an equivalent rectangular duration of 1.7 ms were tested. Each masker was level-adjusted to produce approximately 8 dB of masking. E...
متن کاملLevel dependence of auditory filters in nonsimultaneous masking as a function of frequency.
Auditory filter bandwidths were measured using nonsimultaneous masking, as a function of signal level between 10 and 35 dB SL for signal frequencies of 1, 2, 4, and 6 kHz. The brief sinusoidal signal was presented in a temporal gap within a spectrally notched noise. Two groups of normal-hearing subjects were tested, one using a fixed masker level and adaptively varying signal level, the other u...
متن کاملReconciling frequency selectivity and phase effects in masking.
The effects of auditory frequency selectivity and phase response on masking were studied using harmonic tone complex maskers with a 100-Hz fundamental frequency. Positive and negative Schroeder-phase complexes (m+ and m-), were used as maskers and the signal was a long-duration sinusoid. In the first experiment, thresholds for signal frequencies of 1 and 4 kHz were measured as a function of mas...
