Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.

Sound waves travel almost five times faster underwater than in air, thus sound can be quite an effective means of communicating over distances whales create sounds produced by the movement and release of air through their blowhole, or blowholes, and by the movement of air through the body, not by vocal cords or beaks.
