Subsonic #ows over Helmholtz resonators often cause strong periodic pressure #uctuations inside the resonators over a range of outer #ow velocities. The #ow-excitation mechanism is known to be governed by both the shedding of discrete vortices within the shear layer over the ori"ce and the acoustic
