摘要： An apparatus attenuates noise from a cabinet that houses computer equipment. The apparatus includes a frame, a set of positioning members to position the frame relative to the cabinet, and lateral noise absorption members that are supported by the frame. The lateral noise absorption members define surfaces that form sides of airflow channels through the apparatus. The surfaces are substantially non-parallel to a direction of an airflow pathway through the cabinet when the set of positioning members positions the frame relative to the cabinet. The lateral noise absorption members absorb sound energy emanating from the cabinet (e.g., from a fan assembly within the cabinet). The lateral noise absorption members transform some of the sound energy into low level heat which can be dissipated into the air stream. Additionally, some of the sound energy is reflected back into the cabinet toward the source.
