Acoustic Impedance
Specific acoustic impedance is measure of the ability of a medium to transmit sound waves.
Specific acoustic impedance is measure of the ability of a medium to transmit sound waves.
It can be expressed as
Z = P / v
= ρ c (1)
where
Z = acoustic impedance (Pa s/m)
p = sound pressure (Pa)
v = particle velocity (m/s)
ρ = density of medium (kg/m3)
c = velocity of sound (m/s)
The equation express the coupling between the vibrating particles in the medium.
