In the case of sound waves, the equivalent of kinetic energy is known as acoustic energy. Acoustic energy refers to the energy associated with the oscillating motion of air molecules or particles in any medium through which sound waves propagate.
When a sound wave passes through a medium, it causes the particles in the medium to vibrate and move in a wave-like pattern. This motion of particles carries energy, and that energy is referred to as acoustic energy.
The amount of acoustic energy in a sound wave is related to the amplitude (or intensity) of the wave. Higher amplitudes correspond to greater displacements of the particles and, therefore, more energy associated with the sound wave. The acoustic energy of a sound wave is responsible for its ability to transfer energy and produce effects such as the sensation of loudness when it reaches our ears.
It's worth noting that acoustic energy is a form of mechanical energy, as it involves the movement and interaction of particles in a medium. Sound waves do not possess the same type of energy as kinetic energy, which is associated with the motion of macroscopic objects. Instead, acoustic energy characterizes the energy of the vibrating particles within the medium through which the sound wave propagates.
