Résumé

Les conduits d'air rectangulaires dans les systèmes conventionnels sont composes de silencieux passifs accompagnés de remblai acoustique afin de réduire le bruit de ventilateur. Des procédures établies servant à evaluer le fonctionnement des silencieux à compartiment simple existent depuis quelque temps. Des courbes typiques représentant la ligne complete de silencieux rectangulaires ont récemment été disponibles. La perte dut a l'insertion calculée de façons diverses prenait pour acquis que les silencieux étaient composes d'une piece unique. Plusieurs conduits d'air sont réduits de taille par l'introduction de partitions.
