ABSTRACT:
A system and method for adjusting the volume level of a communications device in response to ambient noise. In one embodiment, ambient noise is sampled once and the volume of a speaker associated with the communications device is increased to, and maintained at, a level sufficient to overcome the ambient noise such that a user can easily carry on a conversation or hear what is being transmitted. In another embodiment, ambient noise is periodically sampled and the volume of the speaker is adjusted in response to the sampled ambient noise. The system and method provides enhanced user convenience and power saving advantages.
