Patent attributes
A panel for attenuating noise includes a core having a first baffle, a second baffle, a first septum, a second septum and a stiffener. The core forms first and second cavities vertically between a first skin and a second skin, wherein the first and the second cavities are each fluidly coupled with perforations in the first skin. The first cavity is formed laterally between the first baffle and the second baffle and has a first cross-sectional geometry. The first septum is laterally between the first baffle and the second baffle and divides the first cavity into fluidly coupled sub-cavities. The second cavity is formed laterally between the second baffle and the stiffener and has a second cross-sectional geometry that is at least approximately identical to the first cross-sectional geometry. The second septum is laterally between the second baffle and the stiffener and divides the second cavity into fluidly coupled sub-cavities.
