An assessment of tonal audibility to ISO 1996-2 is a common requirement in consent conditions for wind farm developments. The technique requires the determination of the sound pressure level of local peaks in the frequency spectrum, along with the average masking noise level in the critical listening band surrounding each peak. An automated tonalit...
