Research on acoustic radiation in a three-dimensional half space

LI Sheng, ZHAO De-you (Department of Naval Architecture, Dalian University of Technology, Dalian 116024, China)  
Many acoustic problems involve half-space domains bounded by a rigid or free surface.This paper is concerned with the acoustic radiation in a three-dimensional half space.The effects of the rigid or free surface on acoustic power and radiation directivity radiated by a pulsating sphere are analytically studied.It is shown that the free surface may achieve a 40dB reduction in the acoustic power in the very low frequency range when the free surface is very near the sphere. However, the effect of the free surface on the acoustic power is insignificant when the surface is far away from the sphere or the excitation frequency is in the high frequency range.The maximum achievement of the rigid surface is a 3dB increase in the acoustic power. The boundary element formulation for half-space acoustic radiation problems is also discussed and validated.
