Eliminating Wind Noise Contamination of Wind Turbine Noise Amplitude Modulation Ratings - First Validation
Year: 2024
Type: conference-paper
Abstract: Microphone wind noise can corrupt outdoor measurements and recordings. It is a particular \nproblem for wind turbine measurements because these cannot be carried out when the wind \nspeed is low. Previous studies simulated the effect that microphone wind noise has on the accuracy \nof a proposed Amplitude Modulation (AM) metric and found that even relatively low wind \nspeeds of 2.5 m/s errors of over 4 dBA can result. It has also been shown that a wind noise detection \nalgorithm can automatically find uncorrupted sections of the recording, and so recover \nthe true AM metrics. This paper shows first results on validating the simulation approach by applying \nthe automatic detection to recordings from pairs of microphones mounted on an acoustic \ncamera array in combination with the results from the AM rating method suggested by the Institute \nof Acoustics Amplitude Modulation Working Group.
