Enter the density of the medium, and the speed of sound through the medium into the calculator to determine the acoustic impedance.

## Acoustic Impedance Formula

The following formula is used to calculate an acoustic impedance.

Z = p * v

• Where Z is the acoustic impedance
• p is the density of the fluid
• v is the speed of sound through the fluid

To calculate acoustic impedance, multiply the density of the medium by the speed of sound through the medium.

## What is acoustic impedance?

Definition:

An acoustic impedance is a measure of the resistance to acoustics that a medium presents due to acoustic pressure applied to the system.

## How to calculate acoustic impedance?

Example Problem:

The following example problem outlines how to calculate an acoustic impedance.

First, determine the speed of sound through the medium. in this example the speed of sound is measured to be 1500 m/s.

Next, determine the density of the medium. In this case, the medium has a density of 500 kg/m^3.

Finally, calculate the acoustic impedance using the formula above:

Z = p * v

Z = 1500*500

Z = 750,000
