For abating noise along a highway, along a railway, or along another
noise-generating way, a wall having an anterior face and a posterior face
comprises, across each face, concrete modules stacked in an upper tier, at
least one intermediate tier, and a lower tier. Each module is plantable
and has a batten. Across each face, the modules are spaced laterally from
one another in courses, one course in each tier, so that modules of each
course straddle modules of the next course above or below said course. In
each of alternate ones of the tiers, a geogrid strip is deployed around
the battens of the modules along the anterior face and around the battens
of the modules along the posterior face, in a zig-zag pattern, so as to
tie the modules along the anterior face to the modules along the posterior
face. The modules across each face are embedded partially in an earthen,
noise-absorbing mass, through which the geogrid strips pass and which is
situated between the modules across the anterior face and the modules
across the posterior face.
