2067332 9105111 PCTABS00004 When concrete paving stones are used as a ground covering, the noise generated by traffic moving thereon constitutes a drawback. To reduce the propagation of noise, the invention proposes concrete blocks which are of a considerably larger format that the customary paving stones. The upper side of the concrete block consists of a sound-absorbing layer (13) of porous concrete. The underside of the concrete block is curved inwards so that the edge regions are more heavily loaded, thus ensuring stability. To channel the surface water away, the concrete block is provided at the sides with vertical slits (16) which are adjacent to the absorption layer (13) consisting of porous concrete.
