Acoustic Impedance Calculator
Calculate the acoustic impedance of a medium from its density and sound speed
Common Materials
| Material | ρ (kg/m³) | c (m/s) | Z (Rayl) |
|---|---|---|---|
| Air (20°C) | 1.2 | 343 | 412 |
| Water | 1000 | 1480 | 1.48e6 |
| Blood | 1060 | 1570 | 1.66e6 |
| Muscle | 1050 | 1580 | 1.66e6 |
| Bone | 1900 | 4080 | 7.75e6 |
| Steel | 7800 | 5960 | 4.65e7 |
| Aluminum | 2700 | 6320 | 1.71e7 |
Formula Used
Z = ρ × c
Where: Z = acoustic impedance (Rayl), ρ = density (kg/m³), c = sound speed (m/s)
