attenu8 products are based on the principle of using a layer of heavy material isolated by a resilient layer. This is an excellent method by which to reduce both airborne and impact sound through floors.
Increasing the relative mass of the total floor construction reduces airborne sound, whilst a properly engineered resilient layer, under loading, will reduce impact sounds.
Since impact sounds through floors are a dominant aspect of transmitted sounds, the type and thickness of the resilient layer is key to producing the required result.
attenu8 resilient layers are engineered to have a low resonance frequency to minimise low frequency
transmitted sound, and excellent durability under
continued dynamic loading.
It is also well known that sound transmitted via flanking paths
needs to be sufficiently reduced to ensure the floor design
determines the expected performance. With attenu8 the
solution to flanking ensures the performance of the floor is not compromised.
