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 localized at a lower loudspeaker. The test stimuli used were seven octave bands of noise (125, 250, 500, 1000, 2000, 4000, and 8000 Hz) and one broadband source (125 ¬ 8000 Hz). The effect of frequency on the threshold was found to be significant (with the 1000 and 2000 Hz bands having the lowest thresholds) while 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.
