The present invention provides a sound barrier 1 including a plurality
of elongate panels 2 having first and second ends 3 and 4,
each panel 2 being formed from a shell 5 defining an inner chamber
6 adapted to contain sound attenuating liquid, said plurality of panels
2 being supportable in a planar configuration by a first support means 7
adapted to engage said first and second ends 3 and 4 respectively.
Preferably the shell 5 is constructed from plastic and/or fiberglass
and the sound attenuating liquid is water which may optionally include other materials
such as sand, slurry, concrete rubble, mud, etc.
Some embodiments include second support means 9 which are attachable
to the post 7 so as to engage the panels 2 and thereby transfer a,
substantial portion, or all of, the weight of each panel 2 to the post 7.
