PURPOSE:To allow the listener to listen to a sound field equal to a reproduced sound filed by a speaker by using a head transfer function compensation device to compensate a transfer function from the speaker till an external ear entrance of the listener and generating a same sound pressure as that at speaker reproduction at the entrance of the external ear at the headphone listening. CONSTITUTION:The device is provided with a sound field control signal processing unit 102 applying sound field control processing on the condition of speaker reproduction to a signal inputted from a signal input terminal 101 and with a head transfer function compensating device 103 compensating a signal outputted to the plural speakers based on the head transfer function by the sound field control signal processing unit 102. Then a headphone 104 reproduces a signal processed by the head transfer function compensating device 103. Thus, the same sound field as that reproduced by the speaker is listened to regardless of headphone reproduction. |
