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...

Context 1
... recommended tone detection process relies on a sharp change in gradient. This is controlled by the tone-seek criterion (Δts), as shown in Figure 2. The search is performed in the forward direction to find the start and end of the noise pause, and then repeated in the reverse direction to find a second set of start and end points. ...
Context 2
... a sharp change in gradient defining the start of the noise pause is found that meets the Δts criterion ( Figure 2). ...
