The invention relates mainly to a concrete pavement tile, which produces a clearly recognizable sound when touched with a blind person's cane or a white stick. In practice it appears useful to incorporate sound sources in guide paths for the blind. The invention has solved this problem by providing a pavement tile (1) with an upper plate (3) of metal, which is supported by the tile at its circumference. The plate can be provided with regularly distributed outwardly projecting tears, bumps or ledges (6). Below the plate there is a sound space (2) which can be formed by pressing the plate, upwardly convex, whereas a hollow executed tile gives the same effect.
