Envelope Correlation

Monaural envelope correlation perception was investigated in listeners with normal hearing and in listeners with cochlear hearing loss. Using a three-interval forced-choice procedure, the task of the subject was to identify the one interval out of three where the noise bands had correlated envelopes. Performance was determined as a function of the spectral separation between noise bands (Δf of 250, 500, or 1000 Hz) and the number of noise bands present (two, three, or five). Although individual differences existed, the results generally indicated better performance for the listeners with normal hearing when the Δf between bands was relatively small; however, there was no significant effect of hearing loss when the frequency separation between bands was greater than 250 Hz. The listeners with normal hearing generally showed decreased performance with increasing Δf, whereas the performance of many of the listeners with hearing impairment usually did not change appreciably with variation in Δf. Both groups of listeners showed improved performance with increasing number of noise bands present for the 500-Hz Δf. Only the listeners with hearing impairment showed significantly improved performance with increasing band number for the 250-Hz Δf; neither group showed improved performance with increasing band number for the 1000-Hz Δf. With five bands present, the performance of the listeners with hearing impairment did not differ significantly from that of the listeners with normal hearing, even for the 250-Hz Δf. It is possible that the poor performance of many of the listeners with hearing impairment when Δf is small may be due to relatively poor peripheral frequency analysis. It is difficult to determine the role of within-channel versus across-channel cues in the effects obtained.

Comodulation Masking Release

This study investigated comodulation masking release (CMR) in a group of children with a history of otitis media with effusion (OME) and a control group of children with no known history of ear disease. CMR was measured both in a monotic condition and in a dichotic condition (where comodulated flanking bands were added to the ear contralateral to the signal). CMR was measured before the insertion of pressure equalization tubes, approximately 1 to 3 months after surgery, and approximately 6 to 8 months after surgery. The results indicated that monotic CMRs were reduced in children who had hearing loss due to OME. Furthermore, the monotic CMR remained abnormally small even when threshold had returned to normal for 1 to 3 months. The monotic CMR was essentially normal 6 to 8 months following surgery. No differences were found between the two groups of children for the dichotic CMR.
