A lightweight and economical sound barrier includes fiberplanks, each having a thin sound absorptive membrane coated on at least one side that functions as a transmission loss barrier; and a concrete barrier having H-columns for mounting the fiberplanks. The H-columns are affixed to the concrete barrier by a plate mounted on the top of the concrete barrier and supported on a lower plate mounted at the bottom of the concrete barrier. The fiberplanks each include precast textured slabs composed of extra long, fine wood fibers that have been chemically processed and pressure bonded with waterproof portland cement, that is a lightweight, strong, fire retardant material with excellent acoustic properties. The fiberplanks have a tongue and groove design. The fiberplanks have a three layer laminated product which is fully integrally bonded to insure a uniform, dependable bond between components. The fiberplank include up to a three and one half inches of foam treatment. The thin sound absorptive membrane is a material such as a masonry waterproofer and a masonry sealer.

Cette invention concerne un écran acoustique léger et économique formé de plaques en fibres, chaque plaque étant revêtue d'une mince couche de matériau phono-absorbant sur au moins une face qui agit comme atténuateur de son, et d'un écran en béton à colonnes en H pour le montage des plaques de fibres. Les colonnes en H sont fixées à l'écran en béton au moyen d'une plaque montée sur le sommet dudit écran et supportées par une plaque inférieure montée à la base dudit écran en béton. Les plaques de fibres comportent chacune des dalles texturées préfabriquées formées de fines fibres de bois de grande longueur ayant subi un traitement chimique et un traitement d'agglomération à du ciment portland hydrofuge par compression, ce dernier matériau constituant un excellent atténuateur de son, léger, résistant et ignifuge. Les plaques de fibres s'assemblent à tenon et mortaise; elles se présentent sous forme d'un produit stratifié trois couches à liaisonnement complet, uniforme et intégral garant d'une excellente résistance à la déstratification. Lesdites plaques comportent une couche de mousse pouvant atteindre trois pouces et demi. La mince couche phono-absorbante est un matériau de revêtement tel qu'un imperméabilisant/scellant de maçonnerie.
