[[Aeroacoustics]] is the study of noise generated by air movement, for instance via turbulence, and the movement of sound through the fluid air. This knowledge was applied in the 1920s and '30s to detect aircraft before [[radar]] was invented and is applied in [[acoustical engineering]] to study how to quieten [[aircraft]]. Aeroacoustics is important for understanding how wind [[musical instrument]]s work.<ref>{{cite book|last=da Silva|first=Andrey Ricardo|title=Aeroacoustics of Wind Instruments: Investigations and Numerical Methods|year=2009|publisher=VDM Verlag|isbn=978-3639210644}}</ref>
