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.

Mode of operation of the damper:

The floor is even. The mass lies on the spring (damper).

By walking on it, the floor starts to swing. Dampers, inert masses on the springs, minimize the impact at 50Hz, the 2nd, 3rd or 4th natural frequency. In this example the 3rd natural frequency is shown.

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.

SIA 181 (2006)

Specifications between two rooms:

minimum requirements new built: Di ≥ 52 dB, L‘ ≤ 53 dB
minimum requirements refurbishment: Di ≥ 50 dB, L‘ ≤ 55 dB

increased requirements new built: Di ≥ 55 dB, L’ ≤ 50 dB
increased requirements refurbishment: Di ≥ 53 dB, L‘ ≤ 52 dB

DIN 4109 (2016)

Recommendation for single-family homes:

normal soundproofing: R‘w ≥ 50 dB, L‘n,w ≤ 56 dB (1)
increased soundproofing: R‘w ≥ 55 dB, L‘n,w ≤ 46 dB (1)

Requirements separating floor of a multi-family home:

normal soundproofing: R‘w ≥ 54 dB, L‘n,w ≤ 50 dB (2)
increased soundproofing: R‘w ≥ 55 dB, L‘n,w ≤ 46 dB (1)

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.

Sound sample airborne sound

Neighbour listening to music

This is what it sounds like when your neighbour listens to music. In the following audio sample, you can only hear something under the silence12 ceiling (Rw = 71 dB), i.e. in your apartment, when the volume in the room is far too high. Turn up the volume control.

Sound sample from the neighbour in your own four walls

And this is what your neighbour's music sounds like within your own four walls. Now turn down the volume a little bit for further sound reproduction.

1st sound sample impact sound

Sound sample of a man striding in rubber heels

You hear a man in rubber heels walking quickly over the ceiling. Select the volume in such a way that the sound impression is created as if he is walking on a conventional beam layer with a simple floor structure (Ln,w = 77 dB). Do not change the volume afterwards.

Sound sample with LIGNATUR silence12 ceiling

This sound impression is created by the Lignatur silence12 ceiling with fill and cement screed structure (Ln,w = 45 dB).

Sound sample with concrete ceiling

And this sound impression is created by a concrete ceiling with cement screed structure (Ln,w = 38 dB).

2nd sound sample impact sound

Sound sample of a man in rubber heels

You once more hear a man in rubber heels walking quickly over the ceiling and the sound impression that is created with a Lignatur silence12 ceiling with fill and cement screed construction (Ln,w = 45 dB).

Sound sample with LIGNATUR silence12 ceiling with false ceiling

This sound impression is created by the Lignatur silence12 ceiling with fill and a false ceiling (Ln,w = 43 dB).

Sound sample with LIGNATUR silence12 ceiling with suspended ceiling

Lignatur silence12 ceiling with fill, cement screed structure and a suspended ceiling(Ln,w = 25 dB).

3rd sound sample impact sound

Sound sample of a man in rubber heels

You once more hear a man in rubber heels walking quickly over the ceiling and the sound impression that is created with a beam layer with fill, a cement screed construction and a false ceiling (Ln,w = 47 dB).

Sound sample with LIGNATUR silence12 ceiling with fill

This sound impression is created by the Lignatur silence12 ceiling with fill and cement screed structure (Ln,w = 45 dB).

Sound sample with concrete ceiling

And this sound impression is created by a concrete ceiling with cement screed structure (Ln,w = 38 dB).
