n3:latexDefinition

\(Z_a= \frac{p}{q} = \frac{p}{vS}\), where \(p\) is the sound pressure, \(q\) is the sound volume velocity, \(v\) is sound particle velocity, and \(S\) is the surface area through which an acoustic wave of frequence \(f\) propagates.

n3:plainTextDescription

Acoustic impedance at a surface is the complex quotient of the average sound pressure over that surface by the sound volume flow rate through that surface.
