Abstract

PURPOSE:To soften the sound and at the same time to enable soutd reproduction of three dimensional space at an equidistance possition from the left and right speakers by letting the reproduction speaker that produces time lag to be only a mid and high frequency range speaker and by not letting the low frequency range signal be mutually erased.
