Innovation Created in Sweden Changes the Way Sound Insulation Is Applied in Light Works, Improves Noise Reduction and Transforms the Relationship Between Residents and Comfort Inside Their Homes
Noise pollution in residences has become one of the biggest modern challenges, and, therefore, researchers are seeking alternatives that reduce the direct impact of noise on residents’ well-being.
The Sound Screw, developed at Malmo University in partnership with Akoustos AB, proposes a mechanical solution that alters the way sound travels through walls.
Internal Spring Technology and Physical Decoupling of Structures
The innovation is based on a mechanism divided into two parts connected by an internal spring, responsible for creating a decoupling between the drywall and the wall structure.
According to the researchers involved in the project, the component prevents sound waves from moving continuously between rigid materials.
The device dissipates part of the vibrational energy and thus reduces the advance of noise before it becomes audible.
This approach distinguishes the Sound Screw from traditional fasteners used in drywall, as it turns the screw into a dynamic barrier within the wall.
Sound Reduction Tests and Impact on Human Perception
In laboratory tests, the equipment showed an approximate reduction of 9 decibels in sound transmission.
Although the number may seem modest technically, experts state that this drop represents a perceived volume up to 50% lower for the human ear compared to common walls.
Therefore, the device stands out in wooden buildings or light construction, where sound leakage is a recurring complaint.

Comparison with Traditional Sound Insulation Methods
Conventional insulation techniques often require additional layers of fiberglass, foams, double structures, and increased wall thickness.
In contrast, the Sound Screw allows for relevant improvements without bulky alterations or added weight to the partitions.
Replacing the original fasteners already elevates wall performance, reduces costs, and simplifies processes in renovations and new constructions.
Practical Adjustments, Cost Savings and Preservation of Usable Space
The installation of the screw follows the standard of common pieces, which eliminates the need for specialized training or specific tools.
The solution reduces the use of traditionally expensive and bulky materials.
Furthermore, it maintains the original thickness of the walls, a decisive factor in compact apartments or homes that need to preserve internal space.
Field Validation Steps and Technical Requirements Before Adoption
Despite the laboratory results, the device is still undergoing validation in different real-life scenarios.
Varied frequencies, humidity, construction formats, and distinct structural conditions need to be analyzed before commercialization.
The technology also relies on certifications and regulations from engineering bodies to move forward to the market.
Expectations for the Future of Silent Construction
Intelligent components with discreet applications, such as the Sound Screw, point to a new phase in residential engineering.
The solution allows for noise reduction without relying on intensive structural interventions, providing immediate comfort and expanding the promise of quieter environments.
For those planning renovations, keeping track of the arrival of this technology can represent significant gains in quality of life.
