Industrial Applications The Sound Fighter® LSE Wall System is ideal for industrial and commercial noise abatement applications. The sound-absorbing feature makes the wall effective in reducing reflective noise that often occurs when surrounding a noise sources with reflective block walls. The light weight modular building block design makes the wall easy to apply to almost any application. The wall is easily disassembled to perform maintenance and reassembled once work is completed. In addition, the wall can be moved to new locations if noise abatement is no longer needed at a particular site.
