Noise diffraction on roads

In recent years, various solutions for the reduction of tyre-road noise have been proposed. These include single en double layer porous asphalt concrete (ZOAB), silent surface dressings and noise barriers. We propose a novel, additional solution contributing to the reduction of tyre-road noise: diffraction by means of side-resonators
