description The method involves generating vibration energy by an elastic blade (1) and dissipating energy to a dissipative structure (6) through rigid frames (4, 5) of a damping device (7). The energy is transferred for assuring filtration and attenuation of an incident pressure wave on very large frequency band. The device is fixed parallel to the blade and the structure is disposed between the frames. An independent claim is also included for a vibration filtering and attenuation device. L'invention concerne un dispositif de filtrage et d'atténuation des vibrations entre un premier élément 2 soumis à une onde de pression incidente et un second élément 3 rayonnant une onde de pression filtrée.Il comprend une structure d'interface de transfert d'énergie vibratoire constituée d'un composant élastique 1 et d'un composant dissipatif 7 fixé en parallèle du composant élastique, pour assurer une filtration et une atténuation de l'onde de pression incidente. Le composant dissipatif 7 est constitué de deux armatures rigides distinctes 4, 5 permettant d'assurer, ponctuellement ou continûment, des fonctions de déviation, éventuellement, par un effet de bras de levier, d'amplification des énergies vibratoires engendrées par les composants élastiques 1 vers un matériau dissipatif 6 interposé entre elles, ledit composant dissipatif 7 assurant un amortissement du composant élastique.
