Title:METHOD AND APPARATUS FOR USING A SOUND SENSOR TO ADJUST THE AUDIO OUTPUT FOR A DEVICE
Abstract
One embodiment of the present invention provides a system that uses a sound sensor to adjust the audio output of a device. During operation, the system uses the sound sensor to determine an ambient sound level for the environment in the proximity of the device. The system then adjusts a volume setting for the device adaptively based on the determined ambient sound level. Adaptively adjusting the volume setting allows the device to adapt to its audio environment and ameliorates potentially-disruptive audio outputs.
