maad.spl.dBSPL_per_bin

maad.spl.dBSPL_per_bin(L, f)[source]

Function to spread the sound pressure level (Energy in dB) along a frequency vector (bins).

Parameters:

Lscalar: Sound Pressure Level in dB
f: array-like (vector (1D)): frequency vector in Hz

Returns:

L_per_binarray-like (vector (1D)): sound pressure level in dB with values corresponding to the frequency’s number of bins

Examples

Spread 80dB SPL from 2kHz to 5kHz with 1kHz step

>>> maad.spl.dBSPL_per_bin(80,[2000,3000,4000,5000])
array([73.97940009, 73.97940009, 73.97940009, 73.97940009])

Spread 80dB SPL from 2kHz to 10kHz with 1kHz step

>>> maad.spl.dBSPL_per_bin(80,[2000,3000,4000,5000,6000,7000,8000,9000,10000])
array([70.45757491, 70.45757491, 70.45757491, 70.45757491, 70.45757491,
     70.45757491, 70.45757491, 70.45757491, 70.45757491])

Spread 80dB SPL from 2kHz to 5kHz with 0.5kHz step
