    Abstract

    This work is concerned with the analysis of log-amplitude fluctuations, and their saturation at large distances, using loudspeaker broadband noise emissions. An experiment is conducted outdoor with a loudspeaker on a wind turbine nacelle at 109m height and a row of microphones extends up to 1278m from the loudspeaker. The measured saturation length presents a similar trend than a theoretical result for tonal noise and spherical waves, but there are large quantitative discrepancies.
