PCT No. PCT/DK94/00320 Sec. 371 Date Feb. 15, 1996 Sec. 102(e) Date Feb. 15, 1996 PCT Filed Aug. 25, 1994 PCT Pub. No. WO95/06167 PCT Pub. Date Mar. 2, 1995The present invention relates to a noise screen adapted to keep down the sound from one side which is characteristic in that the vertical cross section of the noise screen (1) is zigzag-shaped, alternating between absorbing faces (2) and reflecting faces (3), and that the absorbing faces (2) are arranged on the faces tilting upwards towards the sound side. The reflecting faces (3) are preferably transparent for providing an esthetic appearance of the noise screen, but may also be non-transparent for excluding road-users from viewing inhabited areas behind the noise screen (1). The reflecting faces (3) may also in the height as well as the length of the noise screen (1) alternate between being transparent and non-transparent. The noise screen (1) is built up in modules which are placed on posts (8) which seen in cross section may be compressed respectively extended telescopically in the longitudinal direction of the noise screen (1). |
