The unique geometry of the wall is ideal, due to its properties as an acoustic barrier, to serve as a divider between highway noise and residential neighborhoods. Not only does the inner air space prevent the transmission of sound through the wall, but the faceted surface reduces the reverberation of sound off of the wall.
With the use of a simple metal strut, the units are not only secured to one another, but are restrained to a maximum opening dimension.
- Easily assembled requiring fewer workers and less heavy machinery
- The units are able to be transported flat, requiring fewer trucks
- No mortar is necessary for the wall assembly
- The unique geometry of the wall provides a more aesthetically pleasing alternative to traditional highway acoustic barriers.
