    • The present invention relates to an aircraft cabin panel for sound reduction in an interior space. The invention in particular also relates to an aircraft comprising an interior lining with sound-absorbing and sound-reducing panels. In order to provide a panel that is optimized in terms of the design space required by it and in terms of its weight, for use in aircraft, which panel provides improved sound reduction and sound absorption characteristics, an aircraft cabin panel for sound reduction in an interior space is provided, which aircraft cabin panel in at least one region comprises a sandwich construction with a core layer, a first covering layer and a second covering layer. The core layer comprises sound absorbing open-pore core material. The first and the second covering layer are connected to the core layer in a planar fashion. The first covering layer is arranged towards the sound waves to be absorbed and the second covering layer is arranged opposite the first covering layer. The first covering layer is designed so as to be acoustically transparent.
    • 本发明涉及一种用于内部空间中的减声的飞机机舱面板。 本发明特别涉及一种包括具有吸声和减声面板的内衬的飞行器。 为了提供在其所需的设计空间和其重量方面优化的面板,在飞机上使用,该面板提供改进的减声和吸声特性,用于减少噪音的飞机机舱面板 提供内部空间,至少一个区域中的飞机机舱面板包括具有芯层的夹层结构,第一覆盖层和第二覆盖层。 芯层包括吸声开孔芯材。 第一和第二覆盖层以平面方式连接到芯层。 第一覆盖层被布置成朝向被吸收的声波,并且第二覆盖层被布置成与第一覆盖层相对。 第一覆盖层被设计成声透明。
