For greater Peace.
Why don’t timber and wood concrete composite ceilings insulate impact sound adequately for everyone? It’s simple. They can’t control the basses! Our LIGNATUR silence element efficiently solves the problem of low-frequency sound with tuned mass dampers. No more dull droning and rumbling.
Sound samples silence12
First listen to a music example to hear how silence12 ceilings really dampen sound. Use high-quality speakers or headphones.
Further sound samples demonstrate the sound insulation in comparison to other ceiling systems during impact sound excitation.
Requirements for soundproofing
In single-family homes (EFH) simpler constructions are usually sufficient for satisfactory soundproofing. For multi-family homes (MFH) and public buildings, the national standards apply. We recommend you agree to the required specifications for airborne and impact sound with the client in writing.
Sound insulation values
Separation floor constructions - silence 12
Rw,P = 72 dB, C100-3150 = -1 dB, C50-3150 = -9 dB
Ln,w,P = 45 dB, CI,100-2500 = -2 dB, CI,50-2500 = 0 dB

«A reduction of the low-frequency sound transmission is a key topic for protection against impact sound in timber construction. Lignatur solves this problem with a tuned mass damper. Over the past ten years we have improved this system together and gained some important insights. As a testing institute, we are impressed by how thoroughly Lignatur scrutinise this topic.»
Prognosis sound transmission for separation floor constructions
The forecast model for airborne noise insulation in buildings essentially corresponds to DIN EN 12354-1. We developed the forecast model for impact sound transmission in cooperation with the ift Rosenheim following DIN EN 12354-2.
