SoundX® 100

SoundX® 100

General Description

The SoundX® product line offers a flexible acoustical barrier solution for a range of applications. SoundX® Mass Loaded Vinyl flexible sheets are used for sound abatement in automotive, industrial and building applications. The high specific gravity of MLV SoundX®  sheets block the transmission of sound waves and are effective at reducing noise. SoundX® EVA and SoundX® 100 meet or exceed the predicted sound reduction as calculated by the limp mass law: dB = 20*log (f*m) - 33 (where f = frequency in Hz and m=mass in lb/SF)
