Investigation into vertical stereophonic localisation in the presence of interchannel crosstalk

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

Abstract

Listening tests were carried out on 12 subjects, using stereophonic loudspeakers arranged vertically in the median plane, to determine the threshold at which the amplitude of a delayed upper loudspeaker had to be reduced in order for stimuli to be fully localised at a lower loudspeaker. The test stimuli used were seven octave bands of noise (125, 250, 500, 1000, 2000, 4000 and 8000Hz) and one broadband source (125-8000Hz). The effect of frequency on the threshold was found to be significant (with the 1000 and 2000Hz bands having the lowest thresholds) whilst the effect of delay time was non-significant. The threshold for the broadband stimulus was found to be significantly lower compared to each of the noise bands.
