Abstract:
A passive noise attenuation system is described herein. The passive noise attenuation system may comprise an acoustic structure. The acoustic structure may comprise a perforated top sheet and a core accessible via the perforated top sheet. The core may comprise a cell having a plurality of interior walls. The acoustic structure may comprise a back skin. The acoustic structure may comprise an inherently porous material disposed between the top sheet and the back skin, wherein the porous material forms a plane or multiple planes coupled to each interior wall to tangentially subdivide the core.
