Nettet10. apr. 2024 · The most common areal weight for Mass Loaded barriers is 1.0 lb/sf. While the weight changes, the density seldom does, so in reality the thickness changes as well. 1 psf Mass Loaded Vinyl is 1/8″ thick, while 2 psf is 1/4″ thick. MLV is produced by extruding a polymer through a screw and chamber at high temperature and pressure. NettetWe have a 3’ by 6’ wall mounted bass trap with a 10″ deep cavity. Using 1/16th inch MLV (1 lb per sqft) for the limp mass the resonant frequency is calculated by using the basic formula: fo = 170/sqrt(m x d) = 170 /sqrt(1.0 x 10) = 54 Hz. This formula is only useful for large surface limp mass membranes.
