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 suggests that forward masking is more appropriate to derive auditory frequency resolution.

Masked thresholds were measured under simultaneous and forward masking as a function of the number of masking electrodes, and the electrode spacing between the maskers and the target. 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).

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 intensity (masker). More backward than forward masking occurs for very short, silent, time intervals (t). Forward masking is an auditory phenomenon in which the response to a sound transiently alters the physiological response to subsequent sounds (Zwislocki et al., 1959 30.Zwislocki, J., Pirodda, E., and Rubin, H. (1959).On some poststimulatory effects at the threshold of audibility Abnormal auditory forward masking pattern in the brainstem response of individuals with Asperger syndrome Johan Källstrand1 Olle Olsson2 autism spectrum disorders (ASD). In the present study auditory processing was investigated by Sara Fristedt Nehlstedt1 recording auditory brainstem responses (ABRs) elicited by forward masking in adults diagnosed Although electrical stimulation produces an abnormal temporal response in the auditory nerve, temporal perceptual responses are relatively similar to those of acoustic hearing. Psychophysical measures of gap detection, forward masking , modulation detection, temporal integration, and pulse rate discrimination show similar performance in implants and acoustic hearing. 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 adults diagnosed with Asperger syndrome (AS).

Previous 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 response is defined as a reduction in the magnitude of the probe-evoked response caused by the addition of the masking stimulus.

In response to a continuous test tone, single auditory neurons have been shown to produce a re- stimulation in a process known as forward masking. 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 In the present study, auditory brainstem responses (ABRs) were recorded in a forward-masking paradigm in healthy, full-term infants aged 6 weeks (n = 111) and 9 months (n = 62).

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. BACKGROUND Older listeners exhibit deficits in forward masking. If forward-masked sABRs provide an objective measure of the Auditory temporal psychometric functions were obtained for forward masking, backward masking, and for combined forward and backward masking for the case of an impulsive signal in white noise. Forward masking of auditory nerve (N1) and brainstem responses (Wave V) in humans Item menu Backward masking occurs when the masker follows the signal; forward masking occurs when the masker precedes the signal (Fig. 18.5). Interest in temporal masking dates back to the early 1950s, and although the literature clearly demonstrates the effects of temporal masking, the exact mechanisms underlying this phenomenon are unclear ( Durrant and Lovrinic, 1995 ).
