Design optimization methods for rectangular panels with minimal sound radiation

Methods for the design optimization of «quiet» structures using mathematical programming techniques are investigated. The objective of the study is to determine effective, general design methods for determining the optimal design of flat plates with clamped edges that minimizes the total radiated acoustic power. Acoustic response is minimized either at a single frequency or over a wide frequency bandwith. Radiated sound power is calculated using a discretized Rayleigh integral formulation, in conjunction with a finite element solver SAP4 for the solution of the structural problem
