Abstract
An apparatus for controlling acoustical transfer characteristics having an input section for inputting data on acoustical transfer decision factors determining the acoustical transfer characteristics of an audio reproduction output signal, an arithmetic section for calculating a value of control of the acoustic transfer characteristics of the audio reproduction output signal by fuzzy inference based on the decision factors, and an operational section for changing the acoustical transfer characteristics. The factors for compensating for auditory sensation characteristics vary depending upon the sound volume level. Acoustic transfer characteristics suitable for the auditory sensitivity characteristics of the listener with changes in the sound volume can be obtained by a simple operation.
