摘要：<P>PROBLEM TO BE SOLVED: To selectively reflect a specific band component of an acoustic signal in signal level adjustment. <P>SOLUTION: A signal adjustment section 12 adjusts the signal level of an acoustic signal SIN according to an adjustment value G to generate an acoustic signal SOUT. A band division section 22 divides the acoustic signal SIN into N band components B[1] to B[N]. N adjustment value setting sections 30[1] to 30[N] correspond to the band components B[1] to B[N]. Each adjustment value setting section 30[n] sets a variable adjustment value C[n] such that the signal level of the acoustic signal SOUT is suppressed relative to the acoustic signal SIN with increasing a signal level L[n] of the band component B[n]. An adjustment value selection section 26 selects any one of the N adjustment values C[1] to C[N] set by the N adjustment value setting sections 30[1] to 30[N] as the adjustment value G applied to the signal adjustment section 12. <P>COPYRIGHT: (C)2012,JPO&INPIT
