白色的英文怎么读摘要：A trickle vent such as might be ud in association with commercial windows is formed from PVC tubing in two convoluted paths. One or more expansion chambers are provided at turns or directional changes within the tubing which reduce or eliminate noi transmission through the vent. Where a plurality of expansion chambers are ud, each
chamber may be of different length to dampen a different portion of the acoustic spectrum. In a preferred embodiment, the expansion chambers are filled with an acoustic-type foam, and the ends are not completely aled. The tubing preferably bridges two extrusions that form a supporting housing for the vent, and by using two parate extrusions bridged by the tubing, both thermal and acoustic isolation are maintained.酣畅淋漓的意思>酸辣土豆丝的做法
