The invention relates to a road with at least one traffic lane for motorized vehicular traffic, to which road are added sound attenuating means which limit, at least for determined frequency ranges, the lateral emission of sound caused by traffic travelling over the road, and has the feature that a pattern of resonators placed in distributed manner is arranged at least locally over a chosen length along the traffic lane, which resonators each comprise an acoustically hard, non-absorbing resonance space placed under the surface and debouching in an orifice situated at least roughly at a level of the surface of a roadside edge adjacent to the traffic lane, which resonators have resonance frequencies lying in the range of the frequencies of the sound for attenuating, in particular frequencies around about 1 kHz.
