摘要: A panel (20) is provided for attenuating noise. This includes a first skin (22), second (24) and core (26), which forms plurality of cavities (54) vertically between the (22) (24). The (26) wall (48), baffle (50), (50) septum (52). include cavity formed laterally (48) longitudinally (50). (52) divides into fluidly coupled sub-cavities (54A,54B). angularly offset from by an acute angle (88). One or more perforations (34) in are with (54).
