About Acousta-Wal®

Acousta-Wal® sound-absorbing masonry units are your acoustical and aesthetic solution in one product. Whether it’s a school gym, lecture hall or performance arts center, Acousta-Wal is your indoor/outdoor solution to sound absorption and control. Its unique design controls sound transmission as it absorbs sound waves. Acousta-Wal absorbs sound at all frequencies, even the difficult-to-control low frequencies.

 

Acousta-Wal is a performance upgrade option which may be added to a number of structural concrete masonry units. It has a closed top and vertical slots on its face, exposing the inner cavity. Working much like an automobile muffler, the closed-end cavities of the different size units resonate to sound waves of different frequencies, converting them harmlessly to heat.

Acoustics vary with such dynamics as room size, flooring type, window treatments and seating materials. The approach to this analysis depends on if you're trying to dampen sound within the room or trying to block sound from an adjacent area. Contact your local architectural rep to request an engineered acoustical study.
