(b) a reception demodulation circuit that receives a modulated signal transmitted from the sound reception means and demodulates it into an acoustic signal; and a signal that is delayed from the acoustic source signal and demodulated by the reception demodulation circuit. A sound field correction device comprising: a correction circuit that corrects a sound field by inputting a demodulated signal into an adaptive filter and corrects an acoustic source signal so that the difference between the demodulated signal and the delayed signal is minimized. . (2) Utility model registration claim (1), characterized in that the sound receiving means is built into a wireless remote control that performs various operations of the sound system at a listening position remote from the main body of the sound system. The sound field correction device described in .
