Sound attenuating partition

摘要

The sound attenuation of building partitions having a cavity between opposing panels thereof is enhanced by a bowed blanket of mineral fibers in said cavity. The apex of the bow is in compressive contact with one of the panels so that sound waves passing into a panel are dampened before they reach the panel on the opposite side of the partition. The bowed blanket is particularly effective in the frequency range wherein the coincidence effect is troublesome.
