Abstract

L'invention a trait à des systèmes de contrôle du bruit et des vibrations. Des résonateurs (3) aux propriétés réglables sont utilisés avec un système de contrôle électronique (7) pour modifier les bruits ou les vibrations dans une structure (1). L'invention a trait en particulier au contrôle des bruits ou des vibrations quasi-périodiques comprenant une ou plusieurs harmoniques en se servant d'un ou de plusieurs résonateurs (3) adaptatifs.
