What Is the Speed of Sound? The speed of sound is the distance a sound wave travels through an elastic medium. The speed of sound through air at 20 °C is equal to 343meters per second,[2]or roughly 767miles per hour. Speed of sound can be abbreviated assound; for example, 1 speed...
The speed of sound in air is around 768 mi/hr (1,125 ft/sec, 343m/sec), or about 5 seconds per mile, or 3 seconds per kilometer.
