RCAIDE.Library.Methods.Aeroacoustics.Common.decibel_arithmetic.SPL_arithmetic#

SPL_arithmetic(SPL, sum_axis)[source]#

This function computes the total Sound Pressure Level (SPL) from multiple sources using decibel arithmetic.

Parameters:

  • SPL (array_like) – Sound Pressure Level [dB].

  • sum_axis (int) – Axis along which the SPL values are summed.

Returns:

SPL_total – Total Sound Pressure Level [dB].

Return type:

float or array_like

Notes

The function uses decibel arithmetic to sum SPL values from multiple sources. If the input SPL is one-dimensional, it returns the input as the total SPL.

Definitions

‘SPL’
