Power

acoustics.power.lw_iso3746(LpAi, LpAiB, S, alpha, surfaces)[source]

Calculate sound power level according to ISO 3746:2010.

Parameters:
  • LpAi (np.ndarray) – Sound pressure levels of the source \(L_{pAi}\).
  • LpAiB (np.ndarray) – Background noise sound pressure levels \(L_{pAiB}\).
  • S (float) – Area in square meters of the measurement surface \(S\).
  • alpha (np.ndarray) – Absorption coefficients of the room \(\alpha\).
  • surfaces (np.ndarray) – Room surfaces.
Returns:

Sound power level \(L_{w}\).
