Title
(EN) SOUND-PROOFING MEMBER
(FR) ÉLÉMENT D'INSONORISATION
(JA) 防音部材
Abstract
(EN)
This sound-proofing member has one or more sound-proofing cells, each of which has a frame with a hole provided thereto, and a membrane fixed to the frame. The membrane vibrates in response to sound, and has at least one cut part which penetrates from one side to the other side thereof. As a result of this configuration, this sound-proofing member not only has a noise absorption peak at a specific frequency for suppressing noise at a specific frequency, but the peak can also be broadened.
(FR)
L'invention concerne un élément d'insonorisation qui comprend une ou plusieurs cellules d'insonorisation dont chacune a un cadre comportant un trou, et une membrane fixée au cadre. La membrane vibre en réponse à un son et a au moins une partie coupée qui pénètre d'une face à l'autre de la membrane. Il résulte de cette configuration que non seulement ledit élément d'insonorisation a un pic d'absorption de bruit à une fréquence spécifique pour supprimer le bruit à une fréquence spécifique, mais le pic peut être également élargi.
(JA)
この防音部材は、孔部を持つ枠と、枠に固定された膜と、を備える防音セルを1つ以上有し、膜は、音に対して振動するものであり、膜は、その一方の面から他方の面に貫通する1つ以上の切断部を有する。その結果、この防音部材は、特定周波数の騒音を抑制するために特定周波数に騒音の吸収のピークをもつのみならず、ピークに拡がりを持たせることができる。
