Experimental verification of the usefulness of G-weighted level in the assessment of infrasound noise from a wind farm
Environmental assessments of wind turbine noise commonly use microphone heights of 1.5 m or 4 m above ground level, whereas wind turbine measurement standards recommend ground-level measurements on a board to reduce wind-induced interference. This study addresses this methodological uncertainty by…
