- Characterization of sound radiation from thin flexible structures, which encloses sound sources, is required for noise control studies. It involves structural-acoustic coupling between flexible structure and acoustic cavity. The aim of present study is to reconstruct the sound source at uncoupled and coupled frequencies using Equivalent Source Method (ESM) for a rectangular box with the single compliant wall. Data for reconstruction is generated from numerical simulations instead of actual measurements. Effect of the regularization and Signal-toNoise Ratio (SNR) on the accuracy of reconstruction is discussed. The numerical model is developed to understand the coupling phenomena between structural and acoustic subsystem.
