Abstract
An ambient noise compensation system having an automatic gain control to adjust the volume of a desired sound in a listening area. A sound pick-up may be placed in the listening area to capture the sound level, including both the desired sound and ambient noise. A measured value is then determined based on the sound level received by the sound pick-up. The measured value may then be compared to a predictive value to determine an acceptable range. The gain control automatically adjusts the volume of the desired sound to maintain the measured sound within the acceptable range.
