1. In a panel section for use in a sound barrier for acoustical attenuation of a sound source, said panel section having a cementitious body portion; for use with at least two vertically-extending, ground-mounted I-beam columns, each such column having two parallel flanges and a transverse web extending therebetween and being positioned such that its web is substantially parallel to the web of each adjacent column and is substantially normal to a notional wall line defined by said columns; and disposed, in use, in respective vertically-stacked groupings to form one or more wall panels interleaved between adjacent pairs of columns, each wall panel having a pair of end edges disposed, one each, in mechanically-engaged relation, between the parallel flanges of a respective pair of adjacent columns; the improvement comprising: the body portion having defined therethrough a window opening for permitting light transmission through said sound barrier in use; a glazing element adapted for light transmission; and fastening means for securing said glazing element to said body portion to occlude said window opening and to impede the passage of sound therethrough; wherein said body portion has a glaze receiving surface peripherally surrounding said window opening against which the periphery of the glazing element is operatively abutted; and
