Title (EN) SOUNDPROOF STRUCTURE
(FR) STRUCTURE D'INSONORISATION
(JA) 防音構造
Abstract:
(EN) This soundproof structure has: two or more types of resonant sound-absorbing cells including first resonant sound-absorbing cells and second resonant sound-absorbing cells, the resonant sound-absorbing cells being adjacent to each other and being of different types; and open sections provided inside the second resonant sound-absorbing cells, the resonance frequency of the first resonant sound-absorbing cells matching the resonance frequency of the second resonant sound-absorbing cells. As a result, despite being lightweight, thin, and so compact as to be much less than a wavelength, the soundproof structure is capable of achieving a rate of absorption that exceeds 50%, and is preferably close to 100%. It is therefore possible to obtain a prominent soundproofing effect. Furthermore, in being provided with passageways for air and/or heat, etc., the soundproof structure allows air and/or heat to pass therethrough.
(FR) L’invention concerne une structure d'insonorisation comprenant : au moins deux types de cellules résonantes d'absorption acoustique comprenant des premières cellules résonantes d'absorption acoustique et des secondes cellules résonantes d'absorption acoustique, les cellules résonantes d'absorption acoustique étant adjacentes l'une à l'autre et de types différents ; et des sections ouvertes disposées à l'intérieur des secondes cellules résonantes d'absorption acoustique, la fréquence de résonance des premières cellules résonantes d'absorption acoustique correspondant à la fréquence de résonance des secondes cellules résonantes d'absorption acoustique. Par conséquent, bien qu'elle soit légère, mince et compacte afin d'être nettement inférieure à une longueur d'onde, la structure d'insonorisation est capable d'atteindre un taux d'absorption supérieur à 50 % et, de préférence, proche des 100%. Il est donc possible d'obtenir un effet d'insonorisation important. De plus, en étant pourvue de passages pour l'air et/ou la chaleur etc., la structure d'insonorisation permet à l'air et/ou à la chaleur de passer par ceux-ci.
(JA) この防音構造は、互いに隣接し、かつ異なる種類の第1共振型吸音セル、及び第2共振型吸音セルを含む2種類以上の共振型吸音セルと、第2共振型吸音セル内に設けられる開放部と、を有し、第1共振型吸音セルの共振周波数と、第2共振型吸音セルの共振周波数とが一致するものである。その結果、この防音構造は、50%を超え、好ましくは100%に近い吸収率を、波長に比べてはるかに小さく、コンパクトで、軽量で薄くても達成することができ、その結果、高い防音効果を得ることができ、更には、空気及び/又は熱等の通り道を備え、通気性、及び/又は通熱性をも得ることができる。
