Highway Railway Noise Barrier Sound Proof Noise Barriers Suab Barriers laj kab
A suab nrov barrier (tseem hu ua soundwall, sound berm, sound barrier, or acoustical barrier) yog ib qho qauv sab nrauv tsim los tiv thaiv cov neeg nyob hauv thaj chaw siv av los ntawm lub suab nrov. Cov teeb meem suab nrov yog txoj hauv kev zoo tshaj plaws los txo txoj kev tsheb, txoj kev tsheb ciav hlau, and industrial noise sources – other than cessation of the source activity or use of source controls
