Abstract: A wall-mounted acoustic deadening device includes a mounting device including a mounting plate configured to be mounted to a wall and a mounting peg extending from the mounting plate. The mounting peg has a first portion adjacent the mounting plate with a first diameter and a second portion opposite the mounting plate having a second diameter smaller than the first diameter. The device further includes a panel configured to dampen sound, which has a plurality of panel holes extending through a thickness of the panel. A panel hole diameter of one of the plurality of panel holes is less than the first diameter and greater than or equal to the second diameter, and the panel is configured to attach to the mounting device via the mounting peg extending through the one of the plurality of panel holes.

Abstract: A wall-mounted acoustic deadening device includes a mounting device including a mounting plate and a mounting peg extending from the mounting plate and having a first portion adjacent the mounting plate with a first diameter and a second portion opposite the mounting plate having a second diameter smaller than the first diameter. The device also includes at least two panels, each panel including a plurality of panel holes. A panel hole diameter is less than the first diameter and greater than or equal to the second diameter. A first panel is configured to be attached to the mounting device via the mounting peg extending through one of the plurality of panel holes. A second panel is configured to be attached to the mounting device adjacent to the first panel via the mounting peg extending through the one of the plurality of panel holes.
