Theory acoustic
WebbChapter 1 - Basic equations of aeroacoustics. This chapter introduces the basic equation of an acoustic field generated by a moving point sound source and Lighthill's equation describing the generation of aerodynamic sound based on the conservation law of fluid dynamics. How to solve these equations using Green's formula is then presented, with ...

Webb(I.6) The ratio of the particle velocity to the sound velocity is known as the acoustic Mach numberM. One can see from equation (I.5) thatμ is of the same order as the acoustic Mach number. Substituting (I.4) into the system (I.1)-(I.3), one can reduce it to the form ρ0 ∂u ∂t +∇p− ηΔu− ζ+η/3 graddivu= =−ρ∂u ∂t −(ρ0+ρ)(u∇)u(I.7) ∂ρ ∂t WebbThe theory of sound is firmly based in classical physics, in particular Newton's laws of motion, and most especially his second law, which relates force to acceleration through …
