Binaural effects in convolved room impulse responses
Ulrich Reiter, U. Peter Svensson · The Journal of the Acoustical Society of America · 2013
In situations like video and teleconferencing, the acoustical properties of two rooms are involved via a convolution of the two room impulse responses. Reverberation in the two rooms will play quite different roles since the sender room reverberation will partially reach the listener, in the receiver room, from the source direction. Therefore, binaural suppression of reverberation will be less efficient for parts of the total impulse response. Here, the situation is analyzed in terms of a simple room impulse response model with a direct sound followed by an ideal exponential decay. Such a model permits parametric studies, even of convolved impulse responses. Listening test results will quantify the importance of these binaural effects for the perceived quality of speech signals.
