Sounds Generated by the Implosion of Hollow Structures under Hydrostatic Pressure

Abstract

The report describes the mechanism by which a particular structure implodes under hydrostatic pressure. The accelerated motions of the boundary surface, and the magnitude and distribution of the sounds which are produced are calculated. The authors then describe experiments to verify the theoretical analysis of the motion and the sound generation. The limited and incomplete experimental data which are presently available substantially confirm the theoretical analysis. In particular, the theory and experiments show that the principal component of the transient sound is the same in all directions and is proportional to the second time derivative of the volume enclosed by the wetted surface of the imploding structure.
