Abstract

L'invention concerne un écran de protection contre le bruit, comprenant des éléments absorbant le son, superposables, disposés en porte à faux entre des montants. Ces éléments sont constitués par une paroi arrière verticale fermée et une paroi avant perforée, formée d'une partie de rebondissement inclinée et d'une partie horizontale par où pénètre le son Au-dessus de cette dernière, un matériau insonore, non cohérent, remplit l'espace triangulaire compris entre les deux parois. Des plaques insonores supplémentaires peuvent être disposées devant la paroi arrière. En plaçant une paroi avant et un matériau insonore symétriquement de part et d'autre de la paroi arrière commune, on obtient un écran absorbant le son par les deux côtés.
