Abstract : This paper presents a new approach in modeling layered sound absorbing materials. This approach builds a probabilistic model based on the fuzzy structure theory and takes into account internal resonances of the structure. An experimental identification of the mean parameters of the model and its experimental validation are presented.

Keywords : sound-insulation layers vibroacoustic fuzzy structure theory random uncertainties
