Beschreibung
Zusammenfassung:	A sound barrier device, comprising: a first panel having a plurality of perforations; a second panel with no perforations; and a connector connecting the first and second panels and forming an air gap between the first and second panels. The air gap may be formed by attaching the first and second panels to one or more frames, or by placing spacers between the first and second panels. L'invention concerne un dispositif barrière acoustique, comprenant : un premier panneau présentant une pluralité de perforations ; un second panneau sans perforations ; et un raccord reliant les premier et second panneaux et formant un espace d'air entre les premier et second panneaux. L'espace d'air peut être formé par fixation des premier et second panneaux à un ou plusieurs cadres, ou par mise en place d'entretoises entre les premier et second panneaux.
