Résumé

Cette recherche vise `a d´evelopper une m´ethodologie de conception acoustique pour les assemblages de planchers en CLT en utilisant une approche de r´eseaux de neurones artificiels par int´egration de l’analyse du cycle de vie (ACV). 72 mesures en laboratoire sont utilis´ees pour d´evelopper l’outil de pr´evision acoustique. Ils concernent 29 assemblages de planchers diff´erents `a base de CLT. L’indice d’att´enuation acoustique pond´er´e (Rw) et le niveau de pression acoustique normalis´e pond´er´e (Ln,w) sont estim´es avec une pr´ecision de 2 dB. Puis une ´etude ACV est r´ealis´ee sur les assemblages en bois. Les performances acoustiques et leurs impacts environnementaux sont compar´es pour mettre en ´evidence des tendances pouvant guider les d´ecideurs en phase de conception. Cet article a initialement r´ev´el´e que les assemblages de planchers `a base de CLT augmentent g´en´eralement les impacts environnementaux pour obtenir une meilleure isolation acoustique. Cependant, une bonne att´enuation acoustique peut ˆetre obtenue en choisissant des solutions acoustiques adapt´ees.
