A pilot study undertaken in late 2017 using inaudible wind turbine noise and persons having a heightened sensitivity to turbine noise found the test subjects could detect the presence of the signal by way of feeling (rather than hearing) the signal. A control group that had not been exposed to wind turbine noise was unable to detect or sense the inaudible signal. A single case study as a precursor to a further pilot study utilised inaudible wind turbine noise, inaudible white noise, inaudible surf (ocean) noise and an inaudible ventilation fan, was undertaken in a 126 m³ reverberation room and also in a 313 hemi-anechoic room, whilst monitoring of the test subject’s heart rate and brainwaves was obtained. The results of that testing are discussed.
