Matlab gives pic related results.
The cut-off frequency is directly related to the sampling frequency like assumed, but the -3dB point is around 220Hz at 8kHz sampling.
The relative -3dB point moves somewhat if you change the filter length and the amount and position of the nulls change accordingly.
