Convention Paper

Audibility of Phase Response Differences in a Stereo Playback System. Part 2: Narrow-Band Stimuli in Headphones and Loudspeakers

Authors: Choisel, Sylvain; Martin, Geoff

AES Convention 125 · Paper 7559 · October 2008

Abstract

An series of experiments were conducted in order to measure the audibility thresholds of

phase differences between channels using mismatched cross-over networks.

In Part 1 of this study, it was shown that listeners are able to detect very small inter-channel

phase differences when presented with wide-band stimuli over headphones, and that the threshold

was frequency dependent. This second part of the investigation focuses

on listeners' abilities with narrow-band signals (from 63 to 8000\,Hz) in headphones as well as loudspeakers.

The results confirm the frequency dependency of the audibility threshold over headphones,

whereas for loudspeaker playback the threshold was essentially independent of the frequency.
