Interior panels for interiors of aircraft, aircraft, and methods from making interior panels for interiors of aircraft are provided. In one example, the interior panel includes a first relatively hard layer having a first surface that is configured to receive noise from the interior and a second surface that is disposed opposite the first surface. The first relatively hard layer has micro-perforated holes that are formed therethrough and that are spaced apart from each other. A second layer is disposed adjacent to the second surface and has a plurality of openings that are in fluid communication with the plurality of micro-perforated holes. A third layer is disposed adjacent to the second layer. The first relatively hard layer, the second layer, and the third layer are cooperatively configured to attenuate the noise.
提供了用于飞机内部的内部面板、飞机以及制造用于飞机内部的内部面板的方法。在一个示例中,所述内部面板包括第一相对硬层,该第一相对硬层具有被配置为从所述内部接收噪声的第一表面和与所述第一表面相对设置的第二表面。所述第一相对硬层具有穿过其形成的并且彼此间隔开的微穿孔。第二层被设置为邻近所述第二表面,并且具有与多个所述微穿孔流体连通的多个开口。第三层被设置为邻近所述第二层。所述第一相对硬层、所述第二层和所述第三层被协作地配置以减弱所述噪声。
