Patent number: 7986526Abstract: An acoustically absorptive apparatus is provided which includes an acoustically absorptive panel and an attachment mechanism. The acoustically absorptive panel is configured to reside along a side of an electronics rack, and includes a multilayer structure to attenuate noise. The attachment mechanism slidably mounts the acoustically absorptive panel to the electronics rack and facilitates sliding of the panel relative to the rack between retracted and extended positions. In the refracted position, the panel is disposed along the side of the rack, and in the extended position, the panel extends beyond a front or back edge of the electronics rack to facilitate attenuating noise emanating from the rack or an aisle alongside a row of multiple racks. In addition, the acoustically absorptive panel hingedly couples along a vertical edge to the attachment mechanism such that the panel is also rotatable outward away from the side of the electronics rack.Type: GrantFiled: February 25, 2010Date of Patent: July 26, 2011Assignee: International Business Machines CorporationInventors: Glendowlyn F.
