Abstract:
An audio volume control method employs an audio system that includes a first audio device and a second audio device. A communications link connects the first and second audio devices together so that each may communicate with the other. The system includes an audio volume manager that varies the audio output level of the second audio device as a function of the perceived loudness of the second audio device as perceived at the first audio device. To determine the perceived loudness of the second audio device as perceived at the first audio device, the audio volume manager may measure the current distance between the first and second audio devices.
