This dataset consists of acoustic measurements conducted in an aeroacoustic wind tunnel (Poul la Cour Tunnel, PLCT (https://www.plct.dk)) with Kevlar side walls using a microphone array. It is intended to be used in benchmarking exercises for open source software.
The files consist of microphone array measurements. Here frequency-domain data (in 1/12th octave bands) is provided in HDF5 fileformat using the AIAA Array Methods HDF5 File Definition. Each file consist of raw data and associated metadata that includes geometry setup, flow and ambient conditions. This is documented in the ”AIAA Array Methods HDF5 File Definition” document.
The measurement setup is described in the attached pdf-file NACA63018_acoustic.pdf
