Improved Acoustics

Noise control in buildings is of great significance for the health and well-being of the occupants, especially in multifamily dwellings, since they must provide a restful and relaxing environment.

The building envelope must also maintain privacy for the occupant. Noise control is also important in other buildings, such as schools, hospitals, hotels, and offices.

AERCON AAC provides a sound insulation value of 7dB greater than other solid building materials of the same weight per surface area. AERCON’s high surface mass coupled with the mechanical vibration energy damping within its porous structure produces a construction material with exceptional sound insulation properties.

In addition to using a wall material with superior sound insulation properties, it is always essential to construct the wall to close off air leaks and paths by which noise can go around or through the assembly. AERCON AAC’s simple construction methods and details help to eliminate imperfections that allow sound transmission through the walls, thus providing a final wall assembly that offers superior sound insulation characteristics for the occupant.

Also, it should be noted that the results of tests conducted with AERCON AAC block wall construction apply to AERCON AAC reinforced panels. This is because the concrete density of all AERCON AAC products is the same for a given Strength Class.

Sound Absorption

Sound absorption is a major characteristic of the overall acoustic performance of a wall, floor, or roof system. AERCON AAC assemblies can significantly reduce sound transmission from internal sources such as machinery or equipment.

The graph (on the right) indicates the sound absorption of an uncoated/unpainted AERCON AAC surface. The excellent Noise Reduction Coefficient (NRC) for AERCON AAC surfaces provides great sound absorption without any additional measures.
