Abstract (en)
[origin: US6487822B1] A invention relates to a ceiling element (1) for a ceiling (D) consisting of several ceiling elements, comprising a lower metal support (4) which is divided up by links (7) and has holes; and an active sound layer (5) which is arranged in the metal support. The layer is a sound insulation layer or a sound absorption layer for example, especially in the form of an open-pore foam such as a melamine-resin foam. The active sound layer (5) is bonded to the metal support (4). According to the invention, the adhesive (6) is only applied to the link areas (11) and only the inner surfaces of the link areas (11) are bonded. This guarantees a simple, economical construction.
