Abstract :
The paper presents analysis results of sound pressure level of infrasound noise generated by brand new wind turbine from REPOWER type MM92, rated power 2 MW. As results the amplitude spectra of noise for three chosen wind speed values are presented. Additionally, distributions of the sound pressure level with dependence on wind speed for selected resonant and median frequency values are presented. For chosen frequencies linear regression analysis was performed and subjected for a detailed evaluation. Values obtained from measurement were referred to and compared with the limits specified in legislations existing in this area.
