Abstract
Subjects were asked to match a stationary, monaural, “repetition noise” waveform with a sinusoidal waveform presented to the contralateral earphone. The repetition noise waveform was filtered (900–5000 Hz), and had a fixed repetition rate (147, 293, 587 rps). Both the signal and the noiae were maintained at overall levels of approximately 52 dBA. All subjects found strong relationships based upon binaural beats at frequencies corresponding to small integer (1, 2, 3, 4) multiples of the repetition rate. Weaker relationships were found at fractional multiples of the repetition frequency. The perceptibility of frequencies corresponding to certain aspects of the temporal microstructure of the “noise” waveform was also investigated.
