The acoustic barrier, particularly for railways, comprises at least a first sound-proofing member (2), arranged at the sides of a train (3) proximate to at least each bogie (4), and at least a second sound-proofing member (5) arranged on the supporting plane (6) of the rails (8) at the sides of said rails, the second sound-proofing member cooperates with the first sound-proofing member for abating the noise generated by the passage of the train on the rails. <IMAGE> |
