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 The word "acoustic" is derived from the Greek word ἀκουστικός (akoustikos), meaning "of or for hearing, ready to hear" and that from ἀκουστός (akoustos), "heard, audible", which in turn derives from the verb ἀκούω(akouo), "I hear". The Latin synonym is "sonic", after which the term sonics used to be a synonym for acoustics and later a branch of acoustics. Frequencies above and below the audible range are called "ultrasonic" …

Based on this separation in length scales, the classical theory of pressure acoustics is extended by deriving a boundary condition for the acoustic pressure that takes viscous boundary-layer effects fully into account.
