Sound pressure level measurements of wind turbines presents a particular problem for microphone self-noise. Wind turbines typical only generate significant sound under higher wind conditions which are not ideal for sound level measurements. As a result, various schemes are used to reduce wind induced self-noise, these include the use of ground boards, larger than typical foam windscreens, and the use of secondary windscreens. HGC Engineering undertook testing to investigate the insertion loss of various oversize windscreen designs, as well as the reduction of wind induced noise offered by these designs. This paper describes the windscreens tested and presents the insertion loss and wind induced noise results.
