    摘要: The invention relates to a sound-proofing utility configured to limit, at least for a determined frequency range, the lateral emission of airborne sound caused by motorized road traffic, the sound-proofing utility comprising a plate with an acoustically hard outer surface, wherein the plate comprises at least one sound-absorbing side, wherein the sound-absorbing side has a plurality of elongate cavity structures arranged in the plate and debouching at the hard outer surface, and with resonance frequencies in the determined frequency range, for at least partially absorbing the sound incident on the sound-absorbing side. The invention also relates to a travel surface, such as a railway or motorway, provided with such a sound-proofing utility.

    摘要: Diffractor for diffracting sound of traffic on a travel surface with at least one diffraction plate disposed laterally beside the travel surface. The diffraction plate is provided with a pattern of recesses in the upper surface thereof for the purpose of diffracting the traffic noise in a direction which differs from the lateral direction. Each of the recesses is divided into individual resonators by intermediate walls provided in the recesses. The recesses have acoustically substantially non-absorbing walls and are free of acoustically absorbing material. The intermediate walls between adjacent resonators have at least one throughflow opening along which the rainwater can flow from the one resonator to the other.
