Sound energy is the energy produced by sound vibrations as they travel through a specific medium. Sound energy is a form of mechanical energy.
Sound vibrations create sound waves which move through mediums such as air and water before reaching our ears.
Sound energy density, is defined by:
w = (p.v)/c,
- p is the sound pressure;
- v is the particle velocity in the direction of propagation;
- c is the speed of sound.
