How to use the Acoustic Impedance Calculator
- Fill in the values you know. Fields already contain typical example values that you can overwrite.
- Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
- Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
- A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.
If a value is missing or does not make sense, the field shows a short message explaining what to fix.
Formulas used
This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:
impedance = density×sound_velocity/1000000
reflection_coeff = (impedance2 - impedance1)^2/(impedance2 + impedance1)^2
reflection_coeff_custom = (impedance2 - impedance1_custom)^2/(impedance2 + impedance1_custom)^2
reflection_coeff_custom2 = (impedance2_custom - impedance1)^2/(impedance2_custom + impedance1)^2
reflection_coeff_all = (impedance2_custom - impedance1_custom)^2/(impedance2_custom + impedance1_custom)^2
transmission_coeff = 4×impedance2×impedance1/(impedance2 + impedance1)^2
The calculator uses 3 further relationships to link its other values.

Frequently asked questions
What is Acoustic Impedance?
Acoustic impedance is a property of materials that describes how much sound pressure is generated by a sound wave passing through. It is defined as the ratio of sound pressure to particle velocity and is measured in Rayls (Pa·s/m³). Understanding acoustic impedance is essential for various applications in acoustics, audio engineering, and even medical imaging.
How does the Acoustic Impedance Calculator work?
The Acoustic Impedance Calculator is an online tool that computes acoustic impedance based on user-supplied parameters such as density and speed of sound. By entering these values, the calculator uses the formula Z = ρ × c, where Z is impedance, ρ is density, and c is the speed of sound, to provide accurate results.
Why is Acoustic Impedance important in acoustics?
Acoustic impedance is crucial in determining how sound waves travel through different materials. This information can assist in designing better soundproofing materials, optimizing speaker design, and improving audio fidelity in various environments. Additionally, it plays a key role in non-destructive testing and ultrasound diagnostics in the medical field.
Can the calculator be used for different types of materials?
Yes! The Acoustic Impedance Calculator can be utilized for a wide range of materials, including fluids (like water), gases (like air), and solids (like metals and composites). Users need to provide the correct density and speed of sound for the specific material being analyzed.
Is there a limit to the values I can input into the calculator?
While there are no strict limits to the values you can input, it is important to ensure that the values for density (in kg/m³) and speed of sound (in m/s) are realistic and applicable to the materials you are working with. Inputting unrealistic values may lead to erroneous results.
