What Is the Speed of Audio?

The speed of sound varies depending on the temperature of the air through which the audio moves.

On Earth, the speed of audio at body of water level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.two mph (one,225 km/h).

Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air. Therefore, the speed required to break the sound bulwark decreases higher in the atmosphere, where temperatures are colder.

Scientists are interested in the speed of sound, co-ordinate to NASA, because information technology indicates the speed of transmitting a "modest disturbance" (some other way of describing a audio moving ridge) through a gas medium.

The transmission of the disturbance takes identify as molecules in the gas hit each other. The speed of sound likewise varies depending on the type of gas (air, pure oxygen, carbon dioxide, etc.) through which the sound moves.

The get-go controlled flying to interruption the speed of sound — also known equally Mach 1 — took identify Oct. 14, 1947, when examination pilot Chuck Yeager breached the barrier using Glamorous Glennis, an X-ane shipping.

NASA'southward X-43A aircraft flew more than nine times as fast on Nov. sixteen, 2004, flying Mach 9.vi or almost 7,000 mph. That stands as the fastest speed achieved to date by a jet-powered aircraft.
