Abstract
A new Energy Finite Element Formulation was developed for interior noise prediction that includes not only ‘the indirect transmission path associated but also the direct transmission path. The formulation was subsequently extended to model noise control treatments by incorporating appropriate modifications to structural-acoustic and acoustic-acoustic joint matrices. The formulations developed are implemented and the resulting computer program was validated by comparing the predictions from the present development to the results from alternative methods.
