A linear microphone array is shown to be a simple tool to locate aerodynamic sound sources on a horizontal axis wind
turbine. This paper discusses the capabilities and limitations of a linear microphone array to locate sound sources and
measure aerodynamic noise on the blades of a horizontal axis wind turbine rotor. Compared with a planar microphone
array, a linear array requires fewer microphones to achieve the same resolution, a simpler structure to support it and a
simpler signal processing a...
