Sound absorbing rails for road noise barriers that provide excellent performance and workability. Compared to current noise barriers, Silence Keeper rails can reduce noise more effectively, and we think they have the potential to contribute significantly to bettering roadside environments.
Excellent noise performanceTo check the sound absorbing performance of Silence Keeper rails, we conducted field tests compliant with the measurement methods employed by the Ministry of Construction’s Technology Assessment System. As a result, we were able to reduce noise levels by an average of 3.3 dB without raising the height of the noise barrier.This value is equivalent to the adding an additional noise barrier approximately 2 to 3 m high on top of an existing noise barrier.
・Requires little in the way of on-site assembly, ensuring shorter construction time.
・Limited number of components enables safe and secure attachment.
・Can be installed on existing supports without the need to modify or reinforce supports, allowing the reduction of construction costs.
Simple installationCan be easily installed by replacing the top row of an existing standardized noise barrier.
・Reduce the amount of time required for traffic control during installation.
・Can be installed from the road side to ensure high level of safety.
