Detectability of interaural delay in high-frequency complex waveforms

Abstract

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.
