Acoustic energy can be defined as the disturbance of energy which passes through matter in the form of a wave. In other words, it is the energy concerning the mechanical vibrations from its components is called acoustic energy. Any acoustic event has the following stages.
-
- Cause or Generating Mechanism
- Acoustic wave propagation
- Reception Effect
The process in which some other form of energy is converted into sonic energy producing a sound wave is called the transduction process. Sound waves carry energy throughout the propagating medium. The acoustic wave equation is the fundamental equation that describes sound wave propagation. Wave propagation is the key process in any acoustic event. Sound propagates in liquids as a pressure wave and in solids as longitudinal or transverse waves.
