Use of synthesised or actual wind turbine noise for subjective evaluation purposes
Cooper, Steven
ABSTRACT—
There are technical difficulties in producing an accurate wind turbine noise signal for subjective testing of the noise characteristics for different operational scenarios of wind turbines. There are differences in the subjective response when limiting the test signals to infrasound only versus the use of full spectra. The concept of “nocebo” effect that has been presented has relied upon the use of “synthesised wind turbine infrasound” that does not reflect the signature or pressure pulsations observed in full-spectrum field measurements. The validity of “synthesised wind farm infrasound signals” that have been used in such testing is examined and compared with full-spectrum signals.
