Acoustic impedance- pressure and velocity

Click For Summary
SUMMARY

Acoustic impedance is defined as the ratio of pressure to velocity, expressed mathematically as Z = Pressure / Velocity. For a plane propagating wave, acoustic impedance can also be represented by the formula Z = ρ0c, where ρ0 denotes the density of the medium and c represents the speed of sound in that medium. Understanding these definitions is crucial for analyzing wave behavior in various materials.

I find that the acoustic impedance is given by

Z= Pressure/ Velocity


I read that the acoustic impedance of a plane propagating wave is given by

Z = ρ0c.

What is ρ0 and c?

Thanks a lot
