Formula:Z = ρv

Introduction to Acoustic Impedance

Acoustic impedance (Z) is defined as the product of the density (ρ) of a medium and the velocity of sound (v) in that medium. It is a property that characterizes how sound waves propagate through a particular medium. The SI unit of acoustic impedance is pascal-second per cubic meter (Pa·s/m3) or rayl per square meter (rayl/m2).

Parameter usage:


Data validation

The density and velocity should be greater than zero.


This formula is essential in various fields, including ultrasonics, acoustical engineering, and medical imaging. It helps quantify the resistance to the propagation of sound waves in a medium.
