Detectability of interaural delay in high-frequency complex waveforms 论文

摘要

Observers can detect interaural delays in three component stimuli produced by sinusoidally modulating the amplitude of a sinusoidal carrier. Interaural delays are detected in stimuli confined to a high-frequency region even in the presence of an intense, low-pass filtered noise. With 300-Hz modulation of a 3900-Hz carrier, detection of interaural delay is equally good when either the entire stimulus or just the envelope of the stimulus is delayed. In either case performance is as good as with a 300-Hz pure tone.
