Acoustic Interaction in a Spherical Dome/Array
Abstract
A procedure is described which permits the computation of the radiation characteristics of a transducer array given the electrical inputs to the transducer elements. The effects of transducer element interactions (acoustic coupling) and dome-transducer interactions are included in the computation. The dome-transducer configuration chosen for this study is a rectangular array of circular elements mounted in a spherical baffle. This array is surrounded by a concentric, homogeneous dome. Numerical results include (1) radiation loadings on the transducer elements, (2) response (head velocity) of each element to prescribed electrical inputs and (3) farfield beam patterns for the dome/array. The results indicate that element interactions and dome/array interactions can affect element response to the electrical input and thereby degrade transmit performance of the transducer array.
