Audibility of Phase Changes Using Different Kinds of Irradiation
Difference limens of phase are measured presenting steady three-tone-complexes via headphones or via loudspeaker in different acoustic environments. When using a loudspeaker in an anechoic room, almost the same phase differences are audible as when using headphones with an equalizer. The mean difference limens of phase in a reverberant room are about twice as large as those in an anechoic chamber. If the same electric signals are reproduced acoustically by the same loudspeaker but in a reverberant room, the amplitudes and phases of the components are altered in such a way that the sound signals at the ear of the listener may be very different. The results of psychoacoustic experiments reveal that in a reverberant room the signals at the listener's ear, with a high probability, will be on the average less “phase sensitive” than they are in an anechoic room. Thus the results of the headphone experiments represent some kind of “worst case” with respect to the audibility of phase changes.
