70 results about "Sound energy" patented technology

In physics, sound energy is a form of energy. 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. 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=Wₚₒₜₑₙₜᵢₐₗ+Wₖᵢₙₑₜᵢc=∫Vp²/2ρ₀c² dV+∫Vρv²/2 dV, Here: V is the volume of interest; p is the sound pressure; v is the particle velocity; ρ₀ is the density of the medium without sound present; ρ is the local density of the medium; c is the speed of sound.
