Abstract
PURPOSE:To freely control the sense of the upper and lower direction of an acoustic image, by varying the ratio of an output level of the band pass filter for making only the specific frequency band pass, and an output level of the band elimination filter for removing only the specific frequency band. CONSTITUTION:The first signal passing through the band pass filter 6 which makes only the frequency band of 5kHz-10kHz of an input signal pass through, and the second signal passing through the band elimination filter 7 which removes only the same band are made to vary the level ratio by the variable attenuator 10, are mixed by the mixer 9, and are output together.
