Abstract

A method to control spatial impression in sound reproduction in small space has been developed. First, psychological scales of spatial impression are obtained by subjective evaluation on sounds convoluted with impulse responses of various rooms that differ in volume. Next, relationship between the psychological scale of spatial impression and physical features of the corresponding room impulse response is examined. It turns out that a psychological scale can be represented by linear combination of energy distribution on time-frequency plane calculated from an impulse response. Finally, a sound field control method based on the objective measure is invented, and validity of this method is clarified from experiments applied to some real sound fields.
