Formula and methodology
Formula: Acoustic impedance Z = density × sound speed.
The characteristic impedance relates pressure and particle velocity for a plane wave in the supplied uniform medium model.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Medium density — kg/m³; minimum 1.0E-6; maximum 1000000
- Sound speed — m/s; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Medium density | 1000 |
| Sound speed | 1500 |
Acoustic impedance = 1,500,000 Rayl.
Assumptions and limits
- Density and sound speed describe the same medium and conditions.
- The medium is treated as linear and uniform.
- Frequency dependence, attenuation, boundaries, and complex impedance are not modeled.
