Abstract

This paper proposes the theoretical design method of dynamic absorbers for controlling the noise radiation of the structure, which is expanded from “Vibration Control Method of Multi-Degree-of- Freedom Systems using Dynamic Absorbers”. The main point of this method is combined with vibration analysis (finite-element method) and sound analysis (boundary element method). We demonstrate theoretically and experimentally that this method is effective for reducing the radiation noise of the plate structure model, which is a basic element of the structure, by setting up optimum -designed four dual dynamic absorbers.
