ABSTRACT:
A noise control apparatus adapted for installation on top of a straight upright sound barrier, existing or newly erected, is provided which comprises a main body formed from a first screen inclined towards a sound source and a second screen inclined away from the sound source to have a generally V-shaped cross section; the first screen having formed at the top thereof a first additional screen inclined away from the sound source; the second screen having formed at the top thereof a second additional screen inclined towards the sound source; and the distance between free ends of the first and second additional screens being 55 to 88% of that between the tops of the first and second screens. This sound barrier structure has a highly improved effect of noise control while being very compact and lightweight.
