Binaural impulse responses (BIRs) are measured to clarify acoustical characteristics of sound fields in concert halls. Since BIRs indicate the transfer functions of sound fields, an anechoic signal convolved with the BIRs represents the signal which listeners can hear in that sound field to find out the acoustical characteristics of the original sound sources, it is useful to calculated the autocorrelation function (ACF) closely related with subjective evaluation of the listeners. This study investigates the relationship between sound sources and sound fields comparing the inter aural cross correlation functions of BINs and IACF of the the anecoic signal convolved with those BIRs.

Abstract

Binaural impulse responses (BIRs) are measured to clarify acoustical characteristics of sound fields in concert halls. Since BIRs indicate the transfer functions of sound fields, an anechoic signal convolved with the BIRs represents the signal which listeners can hear in that sound field to find out the acoustical characteristics of the original sound sources, it is useful to calculated the autocorrelation function (ACF) closely related with subjective evaluation of the listeners. This study investigates the relationship between sound sources and sound fields comparing the inter aural cross correlation functions of BINs and IACF of the the anecoic signal convolved with those BIRs.
