摘要：
Noises in an interior of an automobile are estimated based on sensed values of sensors that sense a speed (driving speed), an accelerator opening angle, and an engine speed respectively. This estimation is carried out by searching a noise estimation database. A masking characteristic of an audio signal is deduced based on the estimated noises. An equalizing characteristic to prevent a masking of the audio signal is decided based on the masking characteristic, and then the audio signal is equalized.
