Experimental Measurements of the Demo Enclosure

Abstract

Surface vibrations and sound radiation from a small enclosure, meant to simulate the basic characteristics of an equipment enclosure but without the complexity, are investigated experimentally. Several methods of mounting interior shelves in an enclosure are tested, with an attempt to simulate free-free, simply-supported, and clamped boundary conditions. As expected, the measurements show that the vibrations and sound radiation are intimately related to the way the shelves are mounted in the enclosed. Overall, the demo enclosure measurements have yielded valuable information about the effects of the shelf boundary conditions on noise radiation.
