AEROACOUSTICS LABAeroacoustics is concerned with sound generated by aerodynamic forces or motions originating in a flow rather than by the externally applied forces or motions of classical acoustics. Thus, the sounds generated by vibrating violin strings and loudspeakers fall into the category of classical acoustics, whereas sounds generated by the unsteady aerodynamic forces on propellers or by turbulent flows fall into the domain of aeroacoustics.".
