Abstract
Les pièces moulées en matériau antiphonique, en particulier en mousse, servent au revêtement de l'enveloppe des dispositifs d'aération insonorisants. On utilise des plaques 10 adaptées, par la forme de leur contour, à la section droite interne 1 de l'enveloppe. Ces plaques comprennent une perforation 12 se prolongeant à travers leur épaisseur et des conduits 13, 14 sinueux ou coudés à plusieurs reprises, pratiqués dans au moins l'un des côtés opposés des plaques, débouchant par l'une de leurs extrémités, dans la perforation 12 et aboutissant, par leur autre extrémité 15 ou 16, à un bord de limitation des plaques 10.
