Abstract
L'invention porte sur un procédé de réparation d'un défaut (402) dans un panneau de suppression du bruit (100). Le procédé peut être utilisé pour réparer des défauts (402) dans un panneau (100), ces défauts pouvant apparaître au cours de la fabrication ou d'une utilisation normale du panneau (100). Le procédé consiste à éliminer le défaut (402) du panneau de suppression du bruit (100) en créant dans ce panneau une cavité (404), transformer le matériau constitué d'un matériau présentant des propriétés d'insonorisation en un élément d'insertion (408) configuré pour correspondre avec la cavité (404) et placer l'élément d'insertion (408) dans la cavité (404).
