Audio Level Control Device:
An automatic audio level control device for adjusting the audio level of an
appliance in response to changes in ambient sound levels. A microprocessor (16)
monitors the ambient sound produced by an audio appliance using a microphone
(10) to determine average low and high audio thresholds. When the ambient sound
level is outside the threshold range, the microprocessor transmits volume
control signals using infrared emitter (20) to the audio appliance to sustain a
user-defined average audio level.
