pathway.22,23 More specifically, auditory masking has been shown to be aberrant for schizophrenic patients.22 Auditory forward masking refers to the reduced ability to detect a stim-ulus when preceded by a masking sound.24 The masking effect can be assessed as the amount of shift in latency and ampli-tude relative to the unmasked condition.

In fact, auditory bandwidths measured from forward masking thresholds are narrower and more accurate than those measured using simultaneous masking. Temporal masking should not be confused with the ear's acoustic reflex , an involuntary response in the middle ear that is activated to protect the ear's delicate structures from loud sounds.

Forward masking occurs when a sound (the signal) cannot be perceived due to the presence of a preceding sound (the masker).

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.

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).

The neural correlation of forward masking in the auditory system has been investigated for several decades. The fact is forward masking is the better understood of the two, keeping great similarity to other auditory properties like adaptation and fatigue (Moore, 2013). Thus, most of what we know so far is more easily applied to forward than to backward masking. Here, auditory enhancement was measured in eight cochlear-implant (CI) users with direct stimulation.

As backward masking has long been claimed to rely much more heavily on central auditory processes than forward or simultaneous masking (Elliott, 1962 (Elliott, , 1971 Puleo & Pastore, 1980), an Here, we assessed whether the MFB occurs before or after the point of binaural interaction in the auditory pathway by using forward masking in the AM domain in an ipsilateral condition (masker AM and signal AM applied to the left ear with an unmodulated carrier in the right ear) and a contralateral condition (masker AM applied to the right ear 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. • Define the different forms of sound masking: simultaneous, forward and backward.

Neuropsychiatric Disease and Treatment, 6, 289-296. In the study reported here, the additivity of forward masking was used to investigate the characteristics of compression in the auditory system. An energy-summation model predicts that two equally effective maskers, when combined, will result in a 3-dB increase in signal threshold compared to either of the maskers presented individually.

This is illustrated in the left panel of Figure 12.

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 ).

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). Auditory forward masking has been shown to lead to prolonged latencies for waves III and V as well as reduced peak amplitude for wave III and increased wave V amplitude.25 Interestingly, speech-in-noise perception difficulties have been observed for individuals diagnosed with AS, which in part are thought to reflect abnormal peripheral auditory processing.26 Thus, it is pertinent to further Diagram representing the three situations auditory masking can occur.
