COLORATION IN ROOM IMPULSE RESPONSES

A literature review concerning perception of coloration is presented. In the paper we also present a review of general psycho acoustic background material concerning auditory modeling including perception of timbre and amplitude modulation. Furthermore, some classical room acoustic measures for echo perception are considered. Finally, some of the simple engineering measures to rate coloration is evaluated and an auditory signal processing model including a combined time-frequency detection criterion is presented.
