heal.abstract	To characterize the modal structure of the interaction dynamics of plate-like structures functioning as sound reducing systems, we apply the method of Proper Orthogonal Decomposition (POD) to analyze the dynamics of a room-plate-room coupled system. Given the finite element simulation as information on the dynamic response of this coupled system, it is shown that the POD technique identifies unique, optimum spatial patterns (modes) for all dynamic fields such as the sound pressure in the rooms and especially the vibration response of the plate. The Proper Orthogonal Decomposition (POD) technique proves to be a very effective identification tool for structural-acoustical systems. Copyright © 2004 by ASME.	en
