Forward masking is thought to reflect neural adaptation or neural persistence in the auditory nervous system, but it has been unclear where in the auditory pathway this processing occurs. To address this issue, the present study used a “Huggins pitch” stimulus, the perceptual effects of which Auditory enhancement under forward masking in normal-hearing and hearing-impaired listeners Kreft, H. A. & Oxenham, A. J., Nov 1 2019, In: Journal of the Acoustical Society of America. 146, 5, p. 3448-3456 9 p. Research output: Contribution to journal › Article › peer-review The results suggest that the tunings of the auditory filters derived from the forward masking data were considerably sharper than those derived from the simultaneous masking data. The tunings of the auditory filters became much sharper as the center frequency was increased (ratios of 1.30 to 1.38). forward masking conditions are in better agreement with physiological data based on otoacoustic emissions (e.g., Shera et al., 2002; Pickles, 2008).

This phenomenon, referred to as ‘forward suppression’, has been linked to perceptual forward masking. Previous 2013-09-11 · Forward masking is thought to reflect neural adaptation or neural persistence in the auditory nervous system, but it has been unclear where in the auditory pathway this processing occurs. To address this issue, the present study used a “Huggins pitch” stimulus, the perceptual effects of which depend on central auditory processing. With regard to the second assumption, forward masking can be influenced by across-channel mechanisms when there is a possibility of "confusion" of the signal with the masker.

Response amplitudes and latencies to 40 dB HL probe clicks presented in quiet and as a function of the time delay (delta T) following short-duration wideband noise maskers were measured. Forward masking of a fiber's res Responses of single fibers were obtained from the auditory nerve of chinchillas.

Previously, forward masking in the auditory nerve has been measured as a reduction in the neural response to a signal when preceded by a masker. Abnormal auditory information processing has been reported in individuals with autism spectrum disorders (ASD). In the present study auditory processing was investigated by recording auditory brainstem responses (ABRs) elicited by forward masking in … Experiments on auditory backward and forward masking show elevated thresholds for a signal which occurs soon before (backward masking) or soon after (forward masking) another sound of sufficient / Abnormal auditory forward masking pattern in the brainstem response of individuals with Asperger syndrome.

Several key principles of temporal masking were demonstrated in a series of classic studies by Elliott (1962), who reported that: (1) backward masking is more effective than forward masking – given the same time interval between masker and signal, more masking occurs when the masker follows the signal; and (2) masking is more effective when the stimuli are delivered monotically as opposed to … 1. Responses of single fibers were obtained from the auditory nerve of chinchillas. Tone-burst stimuli consisted of a masking stimulus followed by a probe stimulus. Forward masking of a fiber's res Forward Masking of Auditory Nerve Fiber Responses DAVID M. HARRIS AND PETER DALLOS Auditory Physiology Laboratory (Audiology), Northwestern University, Evanston, Illinois 60201 Wave V of the auditory brainstem response and N1 from the ear canal were recorded from normal hearing adults using a forward masking paradigm. Response amplitudes and latencies to 40 dB HL probe clicks presented in quiet and as a function of the time delay (delta T) following short-duration wideband noise maskers were measured. The masking effects for wave V were different than for N1. Forward masking, as measured behaviorally, is defined as an increase in a signal's detection threshold resulting from a preceding masker. Previously, forward masking in the auditory nerve has been measured as a reduction in the neural response to a signal when preceded by a masker.

Forward masking refers to the masking of a tone by a sound that ends a short time (up to about 20 or 30 ms) before the tone begins. Forward masking suggests that recently stimulated sensors are not as sensitive as fully-rested sensor. Backward masking refers to the masking of a tone by a sound that begins a few milliseconds after the tone has

The auditory nerve neurophonic (ANN) was recorded with bipolar electrodes placed on the auditory nerve as it exits the internal meatus. Forward masking is deﬁned as a decreased probe response, depicted by a reduced CAP (B), following a preceding masker. At short masker to probe intervals (MPIs), the ABR wave-V latency is delayed relative to the control (no preceding masker) as illustrated here in A and C. HYPOTHESIS The hypothesis tested was that forward masking of the speech-evoked auditory brainstem response (sABR) increases peak latency as an inverse function of masker-signal interval (Δt), and that the overall persistence of forward masking is age dependent.
