Comment on Baumgart et al.: Infrasound of a wind turbine reanalyzed as power spectrum and power spectral density (JSV, doi: 10.1016/j.jsv.2021.116310, 2021) – Comment on Pilger and Ceranna: The influence of periodic wind turbine noise on infrasound array measurements (JSV, Vol. 388, pp. 188–200, 2017)

Abstract

The infrasonic sound pressure levels due to the blade-tower interaction generated by a wind turbine in the publication by Pilger and Ceranna (JSV, Vol. 388, pp. 188–200, 2017) have been miscalculated with a constant, systematic offset in the order of 36 dB for the sound pressure levels. All values were originally derived from power spectral densities, which will exclusively be considered for presenting corrected figures and results in agreement with Baumgart et al. (JSV, doi: 10.1016/j.jsv.2021.116310, 2021). We also provide further explanation regarding the electrical power of the studied wind turbine. Since the miscalculation is of a systematic nature, the results of our study in terms of estimating distance ranges in which infrasound generated by wind turbines is detected by highly sensitive microbarometers, are still valid. Nevertheless, the findings in our study are inappropriate for drawing any conclusions on the effect of infrasound from wind turbines on human beings.
