Swedish invention promises quieter homes with innovative screws
Our peaceful sleep is often interrupted by noises from neighboring apartments, street traffic, or the sound of a lawnmower. Swedish inventors have proposed solutions to these problems with an innovative project utilizing a construction element with a spring. This invention has the potential to revolutionize construction methods.
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, which significantly improves acoustic insulation in buildings. Laboratory studies have shown that the new screw reduces noise by 9 decibels, equivalent to halving the sound compared to traditional screws.
The greatest benefits of using these screws can be achieved by mounting gypsum boards to walls, eliminating the need for additional sound-insulating layers. This method allows for space-saving by reducing the thickness of building materials, which is crucial in 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 noises.
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 currently seeking business partners interested in testing 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.
