Enhancing Aeroacoustic Wind Tunnel Studies through Massive Channel Upscaling with MEMS Microphones
Daniel Ernst, Armin Goudarzi, Reinhard Geisler +3
This paper presents a large 6~m x 3~m aperture 7200 MEMS microphone array. The array is designed so that sub-arrays with optimized point spread functions can be used for beamformin…
Expert Decision Support System for aeroacoustic source type identification using clustering
Armin Goudarzi, Carsten Spehr, Steffen Herbold
This paper presents an Expert Decision Support System for the identification of time-invariant, aeroacoustic source types. The system comprises two steps: first, acoustic propertie…
Automatic source localization and spectra generation from sparse beamforming maps
Armin Goudarzi, Carsten Spehr, Steffen Herbold
Beamforming is an imaging tool for the investigation of aeroacoustic phenomena and results in high dimensional data that is broken down to spectra by integrating spatial Regions Of…
