spl

spl.spl(levels, msap_prop: numpy.ndarray, rho_0: numpy.ndarray, c_0: numpy.ndarray) → numpy.ndarray

Compute sound pressure level.

Parameters

• levels (Levels) – pyNA component computing noise levels

• msap_prop (np.ndarray [n_t, settings.N_f]) – mean-square acoustic pressure [-]

• rho_0 (np.ndarray [n_t]) – ambient density [kg/m3]

• c_0 (np.ndarray [n_t]) – ambient speed of sound [m/s]

Returns

spl [dB]

Return type

np.ndarray [n_t, settings.N_f]
