n. (context physics English) The energy present in a sound wave
Wikipedia
Sound energy is a form of energy associated with the vibration of matter. The SI unit of sound energy is the joule (J). Sound is a mechanical wave and as such consists physically in oscillatory elastic compression and in oscillatory displacement of a fluid. Therefore, the medium acts as storage for both potential and kinetic energy as well.
Consequently, the sound energy in a volume of interest is defined as the sum of the potential and kinetic energy densities integrated over that volume:
$$W = W_\mathrm{potential} + W_\mathrm{kinetic} = \int_V \frac{p^2}{2 \rho_0 c^2}\, \mathrm{d}V + \int_V \frac{\rho v^2}{2}\, \mathrm{d}V,$$
where
- V is the volume of interest;
- p is the sound pressure;
- v is the particle velocity;
- ρ is the density of the medium without sound present;
- ρ is the local density of the medium;
- c is the speed of sound.
Usage examples of "sound energy".
Thus the frequency of sound energy influences the forms which emerge when that energy becomes visible.
Rather, sonar reflects off the air inside a submarine, or more precisely off the border of water and air through which the sound energy cannot pass.
Using principles of sound energy which will be familiar to anyone who's ever attended a concert, the HDV can do in an hour what would take a platoon of trained deminers a week -and without the terrible casualties all too often suffered by these brave volunteers.
Ames, the sound energy alone can't destroy human tissue, but enhanced by the resonance coming from the rock chamber which is under assault by the acoustic mining equipment, its frequency is reduced so that it can propagate over vast distances.
While a laser beam emits a narrow beam of light energy, the beam from the Sicilian Project would emit a broad fanlike field of sound energy.
Attaching a diaphragm across the narrow end of a horn concentrates the sound energy and allows the needle to cut the wiggly line into a piece of waxor, as in the original, a piece of tin foil wound round a drum (Please look up Edison, Phonograph on the web).

Water was a fine medium for carrying sound energy, far more efficient at it than air, but it had its own rules.
And with as much garbage in the water as there is out here, the bottom's going to soak up most of the sound energy.
