PROBLEM TO BE SOLVED: To provide an audio signal processing device which can perform loudness correction in view of loudness at a real hearing position.SOLUTION: An audio signal processing device comprises: a control part 7 for changing a loudness set value of a master volume 6 and measuring loudness at a real hearing position by using a microphone 101; and an audio signal processing part for performing loudness correction depending on the loudness set value of the master volume 6 and the measured loudness at the hearing position. For example, in the case where a level at 100 Hz is increased by 5 dB when the loudness set value of the master volume 6 is -40 dB, and the level at 100 Hz is increased by 10 dB when the master volume is -60 dB, the level at 100 Hz is increased by 10 dB when loudness at a real hearing point, which is measured when the loudness set value of the master volume 6 is -40 dB is 40 phon (-60 dB). |
