Revolutionary Swedish screws promise quieter living spaces
Typically, peaceful sleep is interrupted by noises from neighbouring apartments, street noise, or a lawn mower. Swedish inventors propose solutions to these problems with an innovative project using a spring construction element. This invention has the potential to revolutionize the construction approach.
Håkan Wernersson, working in the Department of Materials Science and Applied Mathematics at the University of Malmo, along with his team, invented a special screw that can effectively reduce noise.
How does the screw neutralize noise?
Thanks to this innovation, it is possible to reduce the sound levels reaching us by half, significantly improving building acoustic insulation. Laboratory studies have shown that the new screw reduces noise by 9 decibels, which is equivalent to lowering sound by half compared to traditional screws.
The greatest benefits of using these types of screws can be achieved by mounting gypsum boards to walls, eliminating the need for additional sound-insulating layers. This method saves space by reducing the thickness of building materials, which is extremely important in the case of small apartments and houses.
Revolution not only in construction
These sound-absorbing screws from Sweden allow for mounting gypsum boards directly to the wooden elements of the wall. Thanks to built-in springs, they effectively disperse sound waves passing through the wall and wooden beams. As a result, residents are not exposed to bothersome sounds.
The business version of this invention focuses on licensing the right to produce and sell the screw to interested companies. Wernersson and his colleague, Raimo Issalem, are seeking business partners who want to try the product on a larger scale. Through such pilot projects, it will be possible to learn the actual efficiency of the screws in everyday use and further improve them.
