Acoustic theory
text:
Acoustic theory is a scientific field that relates to the description of sound waves. It derives from fluid dynamics. See acoustics for the engineering approach. For sound waves of any magnitude of a disturbance in velocity, pressure, and density we have
- ∂ ρ ′ ∂ t + ρ 0 ∇ ⋅ v + ∇ ⋅ = 0 ∂ v ∂ t + v + ∇ p ′ = 0 In the case that the fluctuations in velocity, density, and pressure are small, we can approximate these as
- ∂ ρ ′ ∂ t + ρ 0 ∇ ⋅ v = 0 ∂ v ∂ t + 1 ρ 0 ∇ p ′ = 0 Where v is the pertur
