Modelling across- and within-channel mechanisms in comodulation masking release
Introduction The audibility of a target sound embedded in another masking sound can be improved by adding sound energy that is remote in frequency from both the masker and the target. This effect is known as comodulation masking release (CMR) [1] and is observed when the remote sound and the masker share coherent patterns of amplitude modulation. While a large body of data has been presented, t...
متن کاملMasking release based on comodulation of target and cue band
Comodulation of masker components can have opposite effects on detection performance: In a simple tone-innoise task, by adding comodulated masker components outside of the critical band, the performance of tone detection is improved. This effect has been termed Comodulation Masking Release (CMR, [2]). Otherwise, if comodulated flanking bands are presented in a modulation detection task, the per...
متن کاملAuditory stream formation affects comodulation masking release retroactively.
Many sounds in the environment have temporal envelope fluctuations that are correlated in different frequency regions. Comodulation masking release (CMR) illustrates how such coherent fluctuations can improve signal detection. This study assesses how perceptual grouping mechanisms affect CMR. Detection thresholds for a 1-kHz sinusoidal signal were measured in the presence of a narrowband (20-Hz...
متن کاملComodulation masking release in speech identification with real and simulated cochlear-implant hearing.
For normal-hearing (NH) listeners, masker energy outside the spectral region of a target signal can improve target detection and identification, a phenomenon referred to as comodulation masking release (CMR). This study examined whether, for cochlear implant (CI) listeners and for NH listeners presented with a "noise vocoded" CI simulation, speech identification in modulated noise is improved b...
متن کاملPhysiological correlates of comodulation masking release in the mammalian ventral cochlear nucleus.
Comodulation masking release (CMR) enhances the detection of signals embedded in wideband, amplitude-modulated maskers. At least part of the CMR is attributable to across-frequency processing, however, the relative contribution of different stages in the auditory system to across-frequency processing is unknown. We have measured the responses of single units from one of the earliest stages in t...
