Abstract
Micro porous absorber structures that be tuned to attenuate noise at the blade pass frequency (BPF) of a cooling fan. The absorber may comprises a panel covered with micro-porous openings with an air gap under the panel. The size of the air gap may be adjusted dynamically to optimize noise attenuation for a fan operating at different speeds.
