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.

High-resolution direct numerical and large-eddy simulation would be ideal but both are usually too costly despite developments in high performance computing. Lower-order modeling approaches are therefore of general interest. A crucial but standing problem for accurate predictive modeling is the estimation of missing noise from the modeled scales. In this paper we address this problem by presenting a novel lower-order framework that couples the one-dimensional turbulence model to the Ffowcs-Williams and Hawkings approach for prediction of the far-field noise of a subsonic turbulent round jet.}, language = {en} } @misc{SchneehagenGeyerSarradjetal., author = {Schneehagen, Erik W. and Geyer, Thomas and Sarradj, Ennes and Moreau, Danielle J.}, title = {Aeroacoustic noise reduction by application of end plates on wall‑mounted finite airfoils}, series = {Experiments in Fluids}, volume = {62}, journal = {Experiments in Fluids}, number = {5}, issn = {0723-4864}, doi = {10.1007/s00348-021-03204-9}, language = {en} } @misc{GeyerFritzscheSarradjetal., author = {Geyer, Thomas and Fritzsche, Christoph and Sarradj, Ennes and Wagner, Hermann}, title = {Der leise Flug der Eule}, series = {Akustik Journal}, volume = {2021}, journal = {Akustik Journal}, number = {2}, pages = {9 -- 17}, language = {de} }
