The study of communication in all its forms has come a long way conceptually and methodologically in the last decade, and this is more true of auditory communication than of the other sensory modalities. In considering the issues involved in communication, it is clear that simple dyadic considerations leave out too many important issues. Background noise, eavesdropping, and deception represent important neglected factors driving the evolution of the mechanisms, development, and ecological adaptiveness of communicatory processes in natural environments.
