Abstract
"VIDRAçA ISOLANTE ACúSTICA". Vidraça isolante acústica comportando pelo menos duas folhas de substrato (2, 3), reunidas em sua periferia com a ajuda de um dispositivo (4) que forma uma junta estanque e quadro intercalar que define com as duas folhas de substrato (2, 3) uma cavidade chata (5) preenchida por um gás, caracterizado pelo fato de que, em pelo menos uma parte da periferia da dita cavidade (5), é formada pelo menos uma micro-cavidade (5a, 5b) que constitui uma zona de perdas termo-viscosas a partir da dita cavidade (5) ao longo de pelo menos uma das paredes internas das duas folhas do substrato (2, 3) que delimita a dirá cavidade (5), as dimensões de uma micro-cavidade (5a, 5b) sendo escolhidas para favorecer a propagação de uma parte das ondas acústicas da cavidade (5) para a micro-cavidade, engendrando perdas termo-viscosas e diminuindo assim a energia acústica da dita cavidade; meios (6e) sendo previstos para conter as ondas acústicas que escapam da dita micro-cavidade (5a, 5b).
