Acoustic panels are disclosed herein. The acoustic panels can include a base, a plurality of sidewalls, a plurality of hinges, and a plurality of connection interfaces. The acoustic panels can include an unassembled configuration in which the acoustic panels are substantially planar or flat. Prior to installation, the acoustic panels can be transitioned to an assembled configuration by folding the sidewalls. The acoustic panels can be coupled to a building structure, such as a ceiling, wall, or suspension system.

Described herein is an acoustic ceiling panel comprising: a first air-permeable body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the first body having an NRC value of at least 0.5 as measured between the first and second major surfaces of the first body; and an attenuation coating applied to the second major surface of the body and the side surface of the body, whereby the attenuation coating seals at least a portion of the second major surface and the side surface of the body.

A ceiling panel having an upper face, a lower face opposite the upper face, and first through fourth edges having a first edge portion adjacent the upper face and a second edge portion below the first edge portion. Each of the first and second edges may have a tongue and each of the third and fourth edges may have a groove. The first edge portion of each of the third and fourth edges may include a first flange having a distal surface. The first edge portion of each of the first and second edges may include a first recess having a first recess wall surface. The first flange may nest within the first recess of an identical adjacent ceiling panel with the distal surface of the first flange of the ceiling panel being spaced from the first recess wall surface of the first recess of the identical adjacent ceiling panel.
