Threshold of hearing versus threshold of sensation for low frequency and infrasound

Residents impacted by wind farms identify the perception of a sensation not necessarily noise. By use of a pressure sound field in a damped reverberation chamber the Threshold of Hearing for Infrasound and Low Frequency (refer Wattanbe and Moller) has been explored together with the Threshold of Sensation for sine waves. Those results are then compared using band limited pulsed signals from a Wind Farm. The differences and what they mean for Wind Turbine investigations are discussed.
