The noise label for the Aircon 10S is below in Figure 2. The key results are the
Declared Apparent Emission Sound Power Level, LWd,8m/s, at 8m/s hub height wind
speed and noise immission predictions for a range of slant distances and hub height
wind speeds.

The assessment established the turbine should not be declared as tonal and therefore no penalty should be applied.
The BWEA Reference Sound Levels at 25m and 60m at an 8m/s hub height wind speed are:
Lp;25m |
47,2 dB (A) |
Lp, 60m |
39,7 dB (A) |
