Abstract

L'invention concerne un écran (1) comprenant : une coque (3) d'aspect moulée à base de mousse de polyuréthanne de densité comprise entre 0,38 et 0,42, la face d'endroit (4) de ladite coque étant dépourvue de revêtement de manière à former face d'aspect dudit écran ; une sous-couche (5) d'absorption acoustique moulée à base de mousse de polyuréthanne de densité comprise entre 0,12 et 0,28, ladite sous-couche surmoulant la face d'envers (6) de ladite coque en la pénétrant sur une fraction de son épaisseur de manière à former une croûte (7) sur-densifiée formant une barrière d'étanchéité entre ladite sous-couche et ladite coque, de sorte que ledit écran soit en outre acoustiquement isolant.
