Sound Insulation Ratings for Partitions: How Far Should Glass Go?

A truly soundproof glass partition. The glass is double-layered, with a clear air gap between the two panes; the top, bottom, and side edges are complete aluminum frames sealed tightly to the structural ceiling and floor, not just to the suspended ceiling grid; the door is a solid soundproof door with a threshold seal strip. From the outside, people inside can be seen talking but no sound can be heard. Avoid: using single-layer glass and open-ended edges, having the partition only extend to below the suspended ceiling grid, using ordinary glass doors without seals, or making the partition a half-height screen while expecting soundproofing.

一道真正隔得了音的玻璃隔間。玻璃是雙層的,兩片之間有明顯的空氣層;上下與側邊的收邊是完整的鋁框並且密合到結構天花與地板,不是只做到輕鋼架;門是實心的隔音門配門檻密封條。從外面看得到裡面的人在說話但聽不到聲音。避免:使用單層玻璃與開放式的收邊、讓隔間只做到輕鋼架天花下方、使用沒有密封的一般玻璃門、把隔間做成半高的屏風卻期待隔音。
