A recess or cavity in an aerodynamic body in motion is usually subjected to intense acoustic and aerodynamic response. This response involves the combined effect of a random aerodynamic 'buffet' and discrete acoustic resonances. A theory has been developed to define the acoustic resonant response, using the radiation resistance of a rectangular cavity as an intermediate step. The acoustic model of the cavity is that of a rectangular room with five walls rigid and one 'soft.' Comparisons of theoretical and experimental response are made at Mach numbers from 0.2 to 5.0. Movies are shown illustrating the boundary layer phenomenon associated with the resonant response of the cavity. (This work supported by a Wright Air Development Division contract.)
