Project Sound Screw

Important results from the project

The Sound Reduction Screw is a revolutionary invention. It can in a simple way solve problems with noise in buildings faster, cheaper and more ergonomic than any other known sound damping solution. It works like a standard screw in the assembly but when mounted it provides a resilient connection between panels and the studs or joists, where a large share of the sound can be muted. The main purpose of the project has been to go from idea to a prototype product and produce a large batch for tests in the market place.

Expected long term effects

We have successfully been able to: a) develop a product design, b) made product as well as production drawings and c) most important of all, produced a prototype screw with all the demanded properties. We have also tested the most important attribute; its ability to reduce noise and d) have amazing results from those tests. We are now ordering the Sound Reducing Screws in larger volumes - 50 000 prototype screws. We are very optimistic about the future and it will be exciting to start up minor as well as full scale tests with customers.

Approach and implementation

There has in this project been a close cooperation with the Swedish screw supplier, their producer in Taiwan and the Swedish producer of springs. Acoustic properties have success fully been tested at the Technical University of Denmark in Copenhagen and mechanical properties at the Faculty of Engineering, Lund University. At Lund University, we have also produced a few early prototypes in 3D-printing in nylon and metal.
