Abstract

A system, method, and computer-usable medium for mitigating audible acknowledgement volume in a vehicle security system. A preferred embodiment of the present invention includes measuring an amplitude of a valid signal, in response to receiving the valid signal; in response to determining the amplitude of the valid signal, comparing the amplitude to a first predetermined threshold; in response to the comparison, adjusting a volume setting of an audible acknowledgement; further adjusting the volume setting in response to measuring ambient noise of a surrounding location; and emitting the audible acknowledgement.

Claims
