VanDercreek, Colin (author), Amiri Simkooei, A. (author), Snellen, M. (author), Ragni, D. (author)This study investigates how embedding microphones in different cavity geometries along the wall of a wind tunnel reduces the measured turbulent boundary layer pressure fluctuations. The effect of these cavities on the measured signal-to-noise ratio of an acoustic source with flow present was also quantified. Twelve cavity geometries defined...journal article 2019
