Abstract: In a standard arrangement with one lead and one lag loudspeaker in anechoic space, simulated by a virtual auditory environment, a measurement of the “echo threshold” (ET) took place for each one of a pair of auditory streams. A second measurement of the ET of each stream followed, but this time the two streams were presented to the listeners simultaneously. The obtained results indicate that it is possible that two simultaneous streams may have different ETs for the same loudspeaker set-up. Additionally the results reveal an “interaction” occurring between the streams since the ETs measured in the second case were different to the ETs measured in the first one. Further studies of the “interaction” were based on the measurements of JNDs for the delay of the lag loudspeaker (absolute threshold of perceptibility). The JNDs are affected in the case of high- frequency band-pass-filtered noise burst when a continuous low-frequency band-pass-filtered noise is added, but not the other way around.
