A methodology to optimize sound pressure responses of a structure, producing a radiation noise due to structural vibration, is presented. The method involves a finite element analysis module to calculate structural vibration, an optimization module to perform sensitivity analysis and structural optimization, and an acoustic module to compute acoustic transfer vectors. The proposed design system is successfully implemented and is demonstrated in the paper using several example problems.
