 Sound is a vibration that travels through an elastic medium as a wave. The speed of sound describes how far this wave travels in a given amount of time. In dry air at 20°C (68°F), the speed of sound is 343,2 meters per second (1,126 ft/s). This equates to 1,236 kilometers per hour (768 mph), or about one mile in five seconds.

 The speed of sound changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
