This paper provides a review of the most well-known and state-of-the-art acoustic imaging methods and recommendations on when to use them. Several exemplary results showing the performance of most methods in aeroacoustic applications are included. This manuscript provides a general introduction to aeroacoustic measurements for non-experienced microphone-array users as well as a broad overview for general aeroacoustic experts.}, language = {en} } @misc{GeyerWindischFritzscheetal., author = {Geyer, Thomas and Windisch, Thomas and Fritzsche, Christoph and Sarradj, Ennes}, title = {Dataset on permeability of wings from owls and non-silently flying birds}, series = {Data in Brief}, volume = {52}, journal = {Data in Brief}, issn = {2352-3409}, doi = {10.1016/j.dib.2023.109825}, language = {en} } @misc{GeyerWindischFritzscheetal., author = {Geyer, Thomas and Windisch, Thomas and Fritzsche, Christoph and Sarradj, Ennes}, title = {Dataset on airflow resistance of wings from owls and non-silently flying birds}, doi = {10.17632/ndcndtstcf.1}, language = {en} } @inproceedings{SchulzeSarradjGeyer, author = {Schulze, Thomas and Sarradj, Ennes and Geyer, Thomas}, title = {Windger{\"a}uschreduktion am Ohr}, series = {Fortschritte der Akustik, DAGA 2016, Aachen, 14.-17.
