A porous skin including a plurality of strips and an acoustic attenuation panel including such a porous skin. The porous skin (1) comprises a plurality of strips (2) arranged transversely to the fluid flow (E) and overlapping transversely one behind the other, each strip (2) upstream of said fluid flow (E) overlapping one or more strips (2) downstream, each of the strips (2) comprising at least one transverse edge, the arrangement of strips (2) has at least one transverse edge comprising a contour defining a line (i.e. A fold line and/or a curve) with deviations, and the arrangement of strips (2) and one or more contours of the transverse edges thereof are configured to form an opening (11) between the strips (2) connecting an outer face of the porous skin (1) to an inner face of the porous skin (1), and prevent the fluid flow (E) from penetrating into said openings (11), so that the porous skin (1) is adapted to allow sound waves to pass therethrough while preventing the fluid flow (E) from passing therethrough.

    包括多个条状物的多孔外皮及包括这种多孔外皮的声学衰减面板。多孔外皮(1)包括横向于流体流(E)布置并且彼此相继地横向交叠的多个条状物(2),所述流体流(E)的上游的每个条状物(2)与下游的一个或多个条状物(2)交叠,条状物(2)中的每个包括至少一个横向边缘,该至少一个横向边缘包括限定具有偏离部的线(即折线和/或曲线)的轮廓,并且条状物(2)的布置和其横向边缘的一个或多个轮廓构造成在条状物(2)之间形成将多孔外皮(1)的外面连接到所述多孔外皮(1)的内面的开口(11),并且防止流体流(E)穿透到所述开口(11)中,因此多孔外皮(1)适于使音波穿过其,而防止流体流(E)穿过其。
