Acoustic insulation: new high-performance technology
Geometric structure that can be applied to all materials (plastics, wood, metal, glass, etc.) with exceptional sound-insulating properties (up to +90%) in a limited space (divided by 3) without extra layers of standard insulating materials.
Benefits
- Exceptional acoustic insulation performance (up to +90% with identical space requirement)
- 3 times less space required (with identical insulation performance)
- Very wide insulation bandwidth (100 hz to 10 000 hz)
- Low-frequency absorption
- Structure applicable to all types of materials (flexible and rigid)
- Potential for adding thermal insulating material
- No extra layers of insulating material required
Issue
To increase acoustic comfort, efforts are made to phonically insulate living spaces from sources of noise. This installation mainly consists of limiting the propagation of sound waves in the air, either by reflecting sound or by absorbing it. To this end, the standard choice is to use very thick material or material that intrinsically has good sound absorption properties, including porous and fibrous material, such as rockwool. These layers of material are generally combined with or integrated into structural elements that separate the areas requiring insulation (partitions or walls in buildings, vehicle bodies or machinery casings).
In many applications, the constraint of available space limits the thickness of insulating material that can be fitted, thereby also limiting sound insulation performance, especially as regards very low frequencies. As a result, acoustic insulation and comfort is only partly provided.
Using current solutions, only an increase in the quantity of insulating material (and therefore an increase in thickness, weight and cost) enables optimal acoustic comfort levels to be achieved. There is no solution that combines very low thickness of material and optimal acoustic comfort.
Solution
We have developed a revolutionary solution, consisting of a rigid or flexible panel with very high-performance properties to reflect or absorb sound, competing with current technology, such as rockwool, glass wool and polymer foams.
Based on its specific macroscopic structure, our technology enables users:
- either to reduce the thickness of structures (partitions, doors, panels, etc.) whilst preserving equivalent sound insulation, resulting in obvious gains in space (3 times less space required!), but also in weight and cost and for a wide variety of materials,
- or to significantly increase sound insulation comfort performance in an equivalent structure thickness and thus achieve unequalled acoustic performance, resulting in a 90% increase in insulation.
