Abstract
A system of flush-mounted transducers has the properties of a spatial filter whose properties can be varied by varying the sensitivities and separations between the constituent transducers of the system. It is shown that, by properly adjusting the sensitivities and the separations, substantial reduction in the response of the system to the pressure field in a turbulent boundary layer can be achieved. Provided that the flow velocities are subsonic, this reduction can be achieved without substantially affecting the response of the transducer system to an incident acoustic pressure field. Particular examples are presented for systems consisting of two- and three-point transducers. Comparison is made of the responses of these systems with the response of a uniform transducer of finite size.
