Speed of Sound Calculator. Sound is a vibration that travels through an elastic medium as a wave. The speed describes how far this wave travels in a given amount of time. The speed of sound is dependent on the density of the air and the density of the air is dependent on the temperature of the air.he speed describes how far this wave travels in a given amount of time.
