Abstract

Masking-level differences (MLDs) for repeated high-pass (2000-Hz) and low-pass (2000-Hz) 100-μs pulses were obtained as a function of the number of transient repetitions and the repetition rate. MLDs compared to the NoSo condition were obtained for the nosπand NoSd binaural configurations (Sd refers to the conditions in which there was a 1.1-ms interaural delay for the transient signals). MLDs of 11–14 dB were obtained for the low-pass transients independent of the number of transients, repetition rate, or type of binaural configuration. MLDs of 2–4 dB were obtained for the high-pass transients only if the transients were repeated 12 or more times. These results for the high-pass transients did not depend on the repetition rate or type of binaural configuration. The results suggest that high-frequency binaural auditory channels can process noisy low-frequency temporal envelopes, but not as well as low-frequency temporal and spectral information.
