| Résumé | The main objective of the work is to assess the acoustic performance of viscoelastic treatments versus the case when the treatment is incorporated as an equivalent added mass layer in various configurations of isotropic or composite structures under diffuse field excitation. The Discrete Laminate Method (DLM) was used in a Transfer Matrix Method (TMM) framework to compute the sound transmission loss of the structure with added noise control treatment. The numerical approach was compared with numerical results from literature and experimental data and was shown to accurately predict the sound transmission loss of composite structures with incorporated noise control treatments. Moreover, parametric studies of various configurations were considered in order to highlight promising behavioral trends for optimal noise control treatments design. |
