ACOUSTA-WALŪ blocks are sound-absorbing, structural concrete masonry units which have closed tops and vertical slots in front of the cavities. ACOUSTA-WALŪ units work like a car muffler-they absorb sound using the Helmholtz resonator principle. The closed-end cavities of the different sized units resonate to sound waves of various frequencies and convert them harmlessly to heat.
ACOUSTA-WALŪ blocks are excellent for auditoriums, gymnasiums, power plants or wherever noise is a problem, indoors and outdoors.
Sound Transmission Loss
In addition to absorbing unwanted noise within a room, ACOUSTA-WALŪ units greatly reduce the transmission of noise to an adjacent room or area.
Low-Frequency Sound Absorption
While ACOUSTA-WALŪ blocks absorb sound at all frequencies, they are particularly effective for absorbing difficult-to-control unwanted low frequency sound energy.
Permanent Sound Control
ACOUSTA-WALŪ blocks are durable, load-bearing, and resistant to mechanical damage. Sound absorption can actually be built into the structure for the life of the building.
Finish Versatility
In addition to being available as ordinary gray blocks which can be painted, ACOUSTA-WALŪ units can have factory-applied glazed or ground face finishes.
Easy Installation
ACOUSTA-WALŪ blocks are installed like ordinary concrete masonry units with the closed tops up. Unlike alternative sound control materials, there is little or no added labor cost for installation. You save time and money.
Trenwyth is proud to introduce Type IV ACOUSTA-WALŪ units. These Type IV units outperform the previously manufactured Type II and Type III units. Use Type IV Units for broad range sound absorption, such as school gymnasiums, lecture halls, and performing arts centers.
