The LSE portable absorptive sound wall contains the acoustic performance of the permanent LSE system while incorporating ease-of-use and sufficient portability. The portable walls have an NRC of 1.05 per ASTM Test Method C423-90a and an STC of 33 per ASTM Test Method E90-90 and E413-87. The standard size measures 18 feet wide by 14 feet high, but the walls can be custom designed in different sizes. They are freestanding for wind loads up to 75 mph, and can easily be anchored with screw-in ground anchors for applications with higher wind loads. All fabricated steel members are hot-dip galvanized after fabrication.
