Abstract
Communication terminals, methods, and computer program products are provided that sense background noise via a speaker that is also used to generate sounds. In some methods of operating a communication terminal, and a speaker signal is supplied to a first speaker to generate sound therefrom, a noise sensing signal is received from the first speaker. The noise sensing signal includes a contribution associated with background noise that is incident to the first speaker. Presence of the background noise in the noise sensing signal is determined.
