An Investigation of Interaural Time Difference Fluctuations, Part 4: The Subjective Effect of Fluctuations in Decaying Stimuli Delivered Over Loudspeakers

The subjective spatial effect of decaying noise signals with interaural time difference fluctuations was investigated. These fluctuations were created by sinusoidal interchannel time difference fluctuations between signals which were presented over loudspeakers. Both verbal and non-verbal elicitation techniques were applied to examine the subjective effect. It was found that the predominant effect of increasing the fluctuation magnitude was an increase in the apparent width of the acoustical environment whilst the apparent size of the perceived sound source did not change.
