Acoustic communication

Acoustic communication is the sending and receiving of messages using sound. Bird song, the roars of lions and the chirping of cicadas are all examples of this. Sometimes the messages are outside the range of human hearing, such as the ultrasonic squeaks of baby rats or the infrasound rumbles of elephants. Most acoustic communication is not language, in the sense that humans use it, although language is one aspect of this adaptation.

About

Hearing, auditory perception, or audition[note 1] is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous matter. It is one of the traditional five senses. The inability to hear is called deafness.

In humans and other vertebrates, hearing is performed primarily by the auditory system: vibrations are detected by the ear and transduced into nerve impulses that are perceived by the brain (primarily in the temporal lobe). Like touch, audition requires sensitivity to the movement of molecules in the world outside the organism. Both hearing and touch are types of mechanosensation.
