Acoustic Impedance Calculator

Formula

To calculate the Acoustic Impedance (Z):

\[ Z = \rho \times v \]

Where:

\(Z\) is the Acoustic Impedance
\(\rho\) is the Density of the Fluid (kg/m³)
\(v\) is the Speed of Sound through the Fluid (m/s)

What is Acoustic Impedance?

Acoustic impedance is a fundamental concept in the study of acoustics that quantifies the resistance of a medium to the transmission of sound waves. It represents the combined effect of a material’s density and compressibility on sound propagation.

Example Calculation

Let's assume the following values:

Density of the Fluid (\(\rho\)) = 1000 kg/m³
Speed of Sound through the Fluid (\(v\)) = 1500 m/s

Using the formula:

\[ Z = 1000 \times 1500 = 1500000 \text{ kg/(m²·s)} \]

The Acoustic Impedance is 1,500,000 kg/(m²·s).
