L'application d'un système de contrôle actif du bruit dans un conduit de longueur finie est étudiée. Les systèmes à entrée unique et sortie unique proposés précédemment sont inappropriés dans ce cas, car la réflexion au niveau des bornes dégrade les performances et/ou des filtres à réponse impulsionnelle infinie sont nécessaires pour une suppression parfaite du bruit. Dans cet article, nous proposons un système à entrée unique et à sortie unique applicable aux conduits de longueur finie, qui permet théoriquement d'obtenir une suppression parfaite du bruit en utilisant uniquement des filtres à réponse impulsionnelle finie. Les longueurs de prise des filtres sont aussi courtes que les délais entre le capteur de référence et la source secondaire. Une mise en œuvre utile du système proposé est également discutée.

Abstract: The application of an active noise control system in a finite-length duct is studied. Previously proposed single-input-single-output systems are inappropriate in this case, because reflection at the terminals degrades the performance, and/or infinite-impulse-response filters are required for perfect noise cancellation. In this paper, we propose a single-input-single-output system applicable to finite-length ducts, which theoretically achieves perfect noise cancellation while using finite-impulse-response filters only. The tap lengths of the filters are as short as the delays between the reference sensor and the secondary source. A useful implementation of the proposed system is also discussed.
