Impact (footfall) sound
In recent years we were able to carry out numerous measurements with a permanent test rig. This has enabled us to gather a formidable volume of data. This collection has makes it possible identify some important trends relating to Elascon superstructures. With the pure Elascon Timber-Concrete composite mix based on Elascon Floor Elascon Floor C 25/30 F 6,5 G 8 LVB, footfall sound will be improved by 3 to 6 dB relative to the measured sound starting level. With further decoupling, where stiffness should be S ≥ 20 Meganewtons per cubic metre, the footfall sound will improve once again.
Airborne sound
As a matter of principle, ceiling underside structures should be designed in such a way that the lowest possible resonance frequency is obtained. As a general rule, sound attenuation above the resonance frequency is markedly increased by decoupling. For this reason, the resonance frequency should be below the acoustic frequency range of the building. The ideal resonance frequency should be kept at a level of < 50 Hertz. The lower frequencies can be achieved by varying the spacing of the shuttering and by increasing the shuttering mass.
Where critical boundaries are involved, or if there are parameters that interact with one another, you may wish to call on the services offered by our external structural physics expert. Because of our vast collection of measurement results gathered during the completion of many previous projects involving different superstructures, we are able to provide you with sound professional advice at a very early stage. Our newly developed, innovative ElascoLoft® product illustrates the potential benefits of our Elascon Timber-Concrete composite, in particular in the sound insulation area.
