Abstract: A sound barrier member for enabling a sound barrier providing good prevention of sound transmission sound reflection. The sound barrier member comprises an enclosure in a generally panel like configuration having a rectangular outer perimeter adapted to engage with other similar members to produce a sound barrier. The enclosure is formed by a front panel (10) and a rear panel unit (16) defining an enclosed space therebetween, with the front panel (10) having a plurality of openings (12) in a desired shape and array allowing sound transmission into the enclosed space. A sound absorbing material (25) is positioned in the enclosed space overlying at least the openings in the front panel (10) and being spaced forwardly of the rear panel unit (16).
