ABSTRACT:
AN on-board vehicle automatic sound volume adjusting apparatus which adjusts the level of an input audio signal in accordance with the difference between the input audio signal level and the running noise level inside the vehicle and which compresses the input audio signal in terms of amplitude according to the level difference. The apparatus inhibits the masking of the minimum component in the reproduced sound volume, and prevents the maximum component therein from becoming excessive when the running noise level is raised.
