>From 'that' report, interesting to see that at the Hum candidate 31.5Hz only 5 dB separates the threshold from audible pickup of Wind Turbine noise at that frequency. Not much more than a doubling of sensitivity to that would make it audible but is considered in the report to be not average capability- so "allright then"? Now this is for WindTurbines , not hum -where the levels are likely to be different across the spectrum and in level, but it highlights to me the way the non average are forgotten when it comes to assessing impact on the general public at large.
Freq Hz 10 12.5 16 20 25 31.5 40 50 63 80 100 125 160 200 Level dB 63 62 61 59 57 55 53 50 48 46 44 42 42 39 T/hold dB 97 92 88 79 69 60 51 44 38 32 27 22 18 14 In this comparison table, where the difference is positive, that is up to about 31.5 – 40Hz, the wind turbine sound is not audible to the "average person" [my added quotes] . The low infrasound frequencies are well below the hearing threshold.
