Abstract

The noise reducer comprises tubular members such as spiral tubes (18), or tubes made of two half-shells (22, 24; 26, 28; 40), having at least partially perforated walls and internally lined with a sound-absorbing material (25; 36), and longitudinally fastened to the top of the barrier. A sound-reflector tube (44) may be nested within each tubular member (40). <IMAGE>
