Abstract
This article discusses the effect of frequency bandwidth on the maximum absolute value of interaural cross-correlation coefficient (IACC) in relation to sound image width (also known as auditory source width, ASW). Subjective experiments concerning sound image width were performed using reproduced sounds of a violin. This article shows that separation into 1/24 and more octave bands and averaging IACC values of these frequency bands leads to a higher correlation to sound image width than IACC in broader frequency bands. Moreover the average of 1/n octave bands of the temporal deviation of interaural time differences and interaural level differences could be confirmed as measures correlating with sound image width.
