Probabilistic modeling by finite elements of the acoustic response of hearing protectors excited by impulse industrial noise

École de Technologie Supérieure de Montréal

This topic tackles the specific objectives OS2 and OS4 and consists in developing a probabilistic model by FE of the sound transmission of industrial impulse noise through different types of protectors. The corresponding FE models will be calibrated/validated in a Bayesian framework from experimental data provided by simplified test benches and will be used to study the underlying mechanisms of sound transmission.
