Measurements and acoustic analyses of infrasound noise emitted by operation of small, building mounted wind farm

Abstract

Operation of modern wind turbines generates infrasound noise which is known as potentially harmful for humans. In presented study, measurements of infrasound noise generated by operation of fi ve vertical axis, building mounted, small wind turbines were conducted. Measurements were taken in urban area at several points and different distances from the installation. Analyses were performed to determine the level of emitted infrasound noise in vicinity of the installation. Comparative analyses were carried out and the achieved results were referred to the limits of sound pressure intensity level of infrasound signals as specifi ed for the working environment in accordance with the Polish standard PN-Z-01338.
