Thresholds for detecting a temporal gap in a 20-Hz-wide band of noise (the target) were measured for the target alone, and in the presence of multiple 20-Hz-wide flanking bands presented to the opposite ear. The flanking bands caused gap thresholds to increase, and this effect was greater at higher levels of the flanking bands. The impairment to gap detection was greater when the flanking bands were comodulated with the target (i.e., had the same envelope) than when they were not comodulated, except at very low and high levels of the flanking bands. A series of supplementary experiments was conducted to investigate why the difference between comodulated and noncomodulated bands was reduced at high levels. The results suggest that this was not due to inter-aural crosstalk. It may have been partly caused by: (1) a central masking effect that reduced the effective sensation level of the target band at high levels of the contralateral flanking bands; (2) reduced independence of the flanking bands owing to broadening of the auditory filters at high levels. The results are discussed in terms of perceptual grouping processes. |
