PURPOSE: To accurately provide a localization of acoustic image normal impulse response signal even when a value of zero or close to zero occurs in the frequency area of an external auditory meatus impulse response signal. ;CONSTITUTION: Digital filters capable of arbitrarily setting coefficient values are used for digital filters 8a and 9a so as to provide a localization acoustic normal impulse response signal as an output signal. A subtraction means 19 calculates the difference between a space acoustic signal convolutionally calculating an input signal 3 and a real sound filed impulse response signal and an external auditory meatus impulse response signal convolutionally calculating the output signal of the digital filter and the external auditory meatus impulse response signal. A serial approximation means 20 determines a coefficient value to minimize the square-law sum of the difference.;COPYRIGHT: (C)1993,JPO&Japio
