Wavebreaker - Mutes traffic noise. Wavebreaker is a new innovative interference sound damper for train and road noise used as a diffractor on noise barriers. Wavebreaker offers a sustainable solution for reducing traffic noise in society, saving costs and people. It is an additional device for noise screens and noise barriers, reducing the needed heights and costs for noise mitigation and noise protection. The technical solution is based on creating destructive sound interference and our "sound-trap" could be called a passive anti-sound device for traffic noise.
