The normalized self-and mutual-radiation impedances for a square piston in a rigid infinite baffle are formulated as quadruple surface integrals by using geometric relations and the impedances are evaluated numerically. Self-radiation resistance and reactance coefficients are compared to the tabulat
The self-radiation impedance of a rigid oscillating disc (ka ~ 1) in the presence of another such disc, stationary and in the same plane, is derived by a simple approximate method. Resistance values are given in the case of identical discs, with 0.2 < ka < 1.0 and separation distances up to 7a. Thes
