Speed of Sound

2 Speed of Sound

The speed of sound is determined by properties of the medium in which it propagates. The sound velocity equals , where B equals the bulk modulus, and rho equals density. The bulk modulus is proportional to stiffness. Thus stiffness (change in shape) and wave speed are related. Density (weight per unit volume) and wave speed are inversely related. The speed of sound in a given medium is essentially independent of frequency.
