Speed Of Sound Definition and Usage
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 343 meters per second,[1] or roughly 767 miles per hour.
Speed of sound can be abbreviated as sound, for example 1 speed of sound can be written as 1 sound.
