The speed of sound — also called ” speed of sound” — corresponds to the speed of propagation of sound waves. So the speed of sound in theair is it of the order of 340 meters per secondunder normal conditions of temperature and pressure.
Speed of sound: temperature, pressure and medium
Unlike the speed of light in vacuum, the speed of sound is not a constant. It varies, for example, depending on the temperature. The hotter it is, the faster the sound travels.
The speed of sound also increases with atmospheric pressure. In a liquid, denser than air, sound travels faster. Thus, in water, the speed of sound — which also depends on the compressibility of the medium — is some 1,480 meters per second. It logically increases again in a solid. For example, in the concretesound travels at a speed of about 3,100 meters per second.
