Acoustic Impedance vs Medium Density

Ver formula →

Formula

## Acoustic Impedance Acoustic impedance characterizes how much resistance a medium offers to the passage of sound waves. ### Formula **Z = rho * v** where rho is the density of the medium and v is the speed of sound in it. When a wave crosses a boundary between media with different impedances, some energy is reflected and some is transmitted.

Exemplo Resolvido

Acoustic impedance of air at sea level (rho = 1.225 kg/m³, v = 343 m/s).

  1. 01Z = rho * v
  2. 02Z = 1.225 * 343
  3. 03Z = 420.2 Pa·s/m (or rayl)
