The effect of attack time and release time of the sound source on the sense of listener envelopment

Abstract

The effect of attack time and release time of the sound source on the sense of Listener Envelopment (LEV) was investigated. From the results of a previous experiment, it was found that there were at least two kinds of sense in LEV, namely, spatial continuity between front and back, and expanse of lateral direction. In this experiment, authors conducted pairwise comparison tests for each sense using simple sine wave stimuli changing four kind of attack time and three kind of release time. Furthermore these short sine waves were convolved with four channel room impulse responses and played back form five channel loud speakers. The result of pairwise comparison showed that the sense of spatial continuity between front and back was related to first attack time and another sense of expanse of lateral direction was related to slower attack time.
