Returns the F-weighting as a function of frequency.

Parameters:

ffloat or array of floats

frequency where the weighting function is computed

normalbool

whether the function should be normalized to have unit gain at 1 kHz.

powerbool

whether the function should express the weighting in terms of acoustic power or signal amplitude

Returns:
