The Reduction of Vertical Interchannel Crosstalk: The Analysis of Localisation Thresholds for Musical Sources

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution › peer-review

Abstract

Musical sources were presented to subjects as phantom images from vertically arranged stereophonic loudspeakers. Loudspeakers were arranged in two layers: 'main' and 'height'. Subjects reduced the amplitude of the height layer until the resultant phantom image matched the position of the same source presented from the lower loudspeaker alone; this was referred to as the 'localisation threshold'. Delays ranging from 0-10ms were applied to the height layer. The localisation threshold was only significantly affected by the ICTD. The median threshold for 0ms was -9.5 dB, which was significantly lower than the -7 dB found for the stimuli in which the height layer was delayed. No evidence was found to support the existence of the precedence effect in the median plane.
