  • Device for fixing a sound-proofing panel on a wall
    Patent number: 7845120
    Abstract: The present invention relates to a device for attaching at least one acoustic panel (1) to a wall (P) characterized by having first attaching means (10) associated with wall (P) and second attaching means (20) associated with said acoustic panel(s) (1), said first (10) and second (20) attaching means being connected to each other by elastic connecting means (30). By adjusting the elasticity of the connecting means, the frequency of each acoustic panel can be individually tuned to treat the various sound frequency ranges.
