Sunnyvale, CA - Quiet Solution (Serious Materials), a leader in sound control wall panels, announced earlier this week that its revolutionary QuietHome® sound-damped floor/ceiling assembly has been awarded UL assembly number L591. This makes it immediately usable in a wide range of commercial and residential applications requiring stringent fire ratings, such as multi-family construction and high-end single family homes wanting high performance soundproofing solutions.

The QuietHome assembly delivers superb noise reduction, with an STC rating up to 65 and an IIC rating up to 70. The STC rating is a measure of sound transmission through the assembly, and the IIC measures how much 'impact' noise is heard in the unit below. These assemblies are particularly good at reducing notoriously challenging 'high heel footfall noise,' with results 20-30db better than conventional assemblies. Overall, these new assemblies deliver a very significant performance improvement of 5-8 IIC points and 8-9 STC points versus conventional poured gypsum concrete assemblies. This can reduce impact noise by half, and airborne noise by two-thirds.

QuietRock® and QuietWood-based assemblies may also be eligible for LEED points, as LEED recognizes the importance of reduced use of materials and embodied energy, as well as of good acoustics.
