The acoustic radiation self-impedance and mutual impedances for rectangular pistons on a rigid cor4ter of any angle are derived and compared with approximate expressions. The resistances are obtained from the pressure in the far field, and the reactances are related to the resistances by the use of
The expression for the pressure in the far field of a rectangular piston on a rigid corner is derived for any angle of the corner. Numerical results are presented, and approximate expressions are given for some special cases.
## A BSTRA CT The effects of radiation impedance on the acoustical output of a sound source are often dismissed or overshnplified. This paper addresses the effects of geometJ T on the radiation impedance of disc, cone and dome piston sources, by developing a geometrical model which can be easily i
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
