Prevailing Background Noise Levels at all Properties to be used as Proxies
8.3.37 Tables 8.2 and 8.3 respectively summarise the results of the quiet daytime and night time
baseline noise monitoring (L A90,10min ) undertaken at Parkview Cottages (Charts 8.1 and 8.2
above) as well as the quiet daytime and night time prevailing background noise levels at each
wind speed for Harburnhead 3 , Aberlyn 4 and Halfwayhouse 5 extracted from the Harburnhead
and Fauch Hill ES Chapters (Appendix 8.6).

8.3.38 These prevailing quiet day and night time background noise levels have been used to derive
appropriate operational noise limits at each wind speed, against which the predicted scheme
and cumulative operational noise levels have been assessed. This assessment is discussed
in detail later in this chapter.
8.4 Topic Specific Design Evolution
8.4.1 As described in Chapter 3: Design Evolution, an initial buffer of 750 m was placed on all
identified residential properties in order to minimise the likelihood of potential NSRs
experiencing significant noise effects from the operational turbines.
