Identification of acoustic sources through an inverse energy method
Résumé
This article deals with the behaviour of acoustic cavities in the mid-high-frequency range. An energy method called simplified energy method (MES) has already been proposed to predict energy levels in acoustic cavities. The direct MES provides energy density repartitions from the knowledge of input power and power dissipated at the boundaries. In this article we propose that the MES can be used to solve inverse problems. More precisely, the dissipated energy at the acoustic domain boundaries are retrieved from the knowledge of energy densities. The inverse MES formulation is first defined and a simple acoustic cavity test case is analysed, displaying the efficiency of the proposed method. The nature and the quality of input data as well as other parameters will be considered.
