Abstract : The work is concerned with the specific case of an array of circular pistons on a sphere surrounded by a concentric spherical dome. The dome is divided into vibrating areas which are approximated by circular pistons and are referred to here as dome pistons. The transducer pistons are driven electrically, these in turn drive the dome pistons acoustically, and the vibration of the latter radiates sound into the exterior medium. The dome pistons interact with each other acoustically through the medium outside the dome.
