Acoustical Barrier


AQUEST CORPORATION supplied SOUND SEAL’s industrial-grade composite acoustical barrier and absorber material to construct a sound barrier wall to contain nuisance off-site noise at a power plant in Massachusetts. The Aquest team assisted in specifying and supplying a set of flexible acoustical panels which were suspended from 20 ft. tall structural framework. The Sound Seal BBC-EXT-R-2” noise barrier- /absorber- composite was utilized to provide superior sound transmission loss performance (Sound Transmission Class [STC] rating of 34), as well as reflective noise reduction (Noise Reduction Coefficient [NRC] of 0.75). The material was designed for outdoor use designed to provide a minimum of 10 year life in the harshest environment.
