An environmental sensor distinguishes between a plurality of different ambient acoustic environments and communicates with an audio gain circuit which automatically adjusts the audio characteristics of the speaker and microphone of a wireless communications assembly for more optimum audio performance. The wireless communications assembly preferably includes a hands free adapter coupled to a wireless communications device such as a cellular telephone. The adjustments to the audio characteristics are according to predetermined settings for the identified ambient acoustic environment which are preferably stored in memory associated with the audio gain circuit. In this manner, the audio characteristics are automatically adjusted for the actual ambient acoustic environment that the wireless communications assembly is operating in.
