Abstract: Auditory image control in the 5.1 reproduction system has been a challenge due to the arrangement of loudspeakers, especially in the lateral region. To suppress typical artifacts in pair-wise constant power algorithm, a new gain ratio between Left and Left Surround channel has been experimentally determined. Listeners were asked to estimate the gain ratio between two speakers for seven lateral positions so as to set the direction of the sound source. From these gain ratios, a polynomial function was derived of in order to that parametrically represented the gain ratio in an arbitrary direction was derived. The result of validating experiments showed that the new function produced stable auditory imagery in the lateral region.
