Swedish innovation springs into action with noise-reducing screw
Typically, peaceful sleep is interrupted by noises from neighbouring flats, street noise, or a lawnmower. Swedish inventors have proposed solutions to these problems with an innovative project using a construction element with a spring. This invention has the potential to revolutionise the construction approach.
Håkan Wernersson, working in the Department of Materials Science and Applied Mathematics at the University of Malmö, along with his team, has invented a special screw that can effectively reduce noise.
How does the screw neutralise 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 halving the sound compared to traditional screws.
The greatest benefits of using these types of screws can be achieved by mounting plasterboards 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 for small flats and houses.
Revolution not only in construction
These sound-absorbing screws from Sweden allow for mounting plasterboards directly to the wooden elements of the wall. Thanks to built-in springs, they effectively disperse sound waves passing through the walls 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 assess the actual efficiency of the screws in everyday use and further improve them.
