ABSTRACT
Most electroacoustic transducers will be used in a sound-reecting environment. The inuence of the room and particularly its surfaces on a sound source have long been of interest to both engineering and science [1-7]. In the simplest theoretical case the environment may be that of a single, plane, rigid, innitely large reecting surface. When more surfaces are present or when the surfaces have limited size or impedance, the mathematical theory of the inuence of the environment on the transducer becomes more complicated. It will then usually be difcult or impossible to nd an analytical solution to the problem, and one will have to resort to numerical solution methods.
