Audio communication is any form of transmission that is based on hearing. Audio communicative forms are found in such platforms as audio books, television, movie soundtracks and music records.
The audible part of communication is based on signals that reach a single person or groups of people. For instance, music is an auditory medium that incorporates instruments and vocals in an organized and continuous manner for the listener. Audio transmissions can also be found in commercials.
Human hearing is necessary to receive audio transmissions that come from a person or media format. Audible communication typically comes from the mouth in the form of spoken language.
