| description | Structure pour bloquer de l'énergie d'onde acoustique, la structure comprenant une structure de support et au moins une membrane résonante (110, 1110, 1600) couvrant une cellule de la structure de support, dans laquelle l'au moins une membrane résonante (110, 1110, 1600) comprend au moins un poids (113, 520, 620, 1112, 1121), et dans laquelle l'au moins une membrane résonante (110, 1110, 1600) comporte une fréquence anti-résonante.
The invention provides a hybrid acoustic barrier and an absorber. The acoustic barrier structure can include a support structure that defines a plurality of cells, a weight attached to the support structure, and at least one resonant membrane covering one of the plurality of cells. The at least one resonant membrane can comprise at least one weight. The at least one resonant membrane can have an anti-resonant frequency and the support structure with the weight can provide wide frequency band gaps between odd resonance modes while suppressing structure-membrane coupled modes to enable the anti-resonance of the at least one resonant membrane. |
