Abstract

L'invention propose un absorbeur sonore passif (3, 4, 6, 7, 8), comprenant une cavité fermée (30, 80) débouchant vers l'extérieur par une direction d'entrée (D3) par un col traversant la paroi avant pour former un résonateur de Helmholtz pour une première fréquence. Selon l'invention, cet absorbeur comprend en outre au moins un élément mobile, ou pastille (32, 42, 62, 72a, 72b), suspendu ou maintenu par des suspensions (33, 43, 6140) dans une position obstruant ledit col de façon non étanche. La raideur relative des suspensions et de la pastille est déterminée pour que l'ensemble résonne en une vibration selon un déplacement en "piston" à une deuxième fréquence différente de la première fréquence, réalisant une absorption pour cette deuxième fréquence ou plage de fréquences. Une version hybride comprend une bobine (324) pilotée pour adapter l'impédance acoustique de l'absorbeur. L'invention propose une paroi acoustique comprenant une pluralité de tels absorbeurs réalisés par une structure répétitive débouchant par des perforations recevant chacune une telle pastille, ainsi qu'un procédé de conception et de fabrication d'un tel absorbeur ou paroi.
