    • An acoustic structure that includes a honeycomb having cells in which septum caps are located. The septum caps are formed from sheets of flexible material that may be perforated before or after the material is inserted into the honeycomb. The flexible material is sufficiently flexible to allow folding into the shape of a septum cap. The flexible material is also sufficiently stiff to provide frictional engagement and locking of the septum cap to the honeycomb cell when the cap is inserted into the honeycomb during fabrication of the acoustic structure. An adhesive is applied to the septum caps after the caps have been inserted into the honeycomb cells to provide a permanent bond.
    • 一种声学结构,其包括具有隔膜盖所在的单元的蜂窝体。 隔膜帽由可以在材料插入蜂窝中之前或之后穿孔的柔性材料片形成。 柔性材料足够柔软以允许折叠成隔膜帽的形状。 柔性材料也足够坚硬,以便在声学结构的制造过程中当盖被插入蜂窝体时,提供摩擦接合和将隔垫盖锁定到蜂窝状电池。 在将盖子插入蜂窝状电池中之后,将粘合剂施加到隔膜帽以提供永久性粘结。

    • A sound-eliminating board including sequentially bonded sound transmissible top layer, rigid sound-eliminating middle layer, and elastic sound-eliminating bottom layer. The sound transmissible top layer allows sound waves to penetrate through it into the rigid sound-eliminating middle layer, which includes a plurality of checkered partitions to define a plurality of open-topped small compartments. Sound waves penetrated into the rigid sound-eliminating middle layer reflect repeatedly in the small compartments to result in energy dispersion and counterbalanced energy due to overlapped amplitude of reflected sound waves, and are finally eliminated. In case of any residual low-frequency sound waves that penetrate through the rigid sound-eliminating middle layer into the elastic sound-eliminating bottom layer, they are further eliminated in the bottom layer.
    • 声音消除板包括依次粘接的声音传播顶层,刚性消声中间层和弹性消声底层。 声音传播顶层允许声波穿透其进入刚性消声中间层,其包括多个方格分隔物以限定多个开顶的小隔间。 穿透到刚性消音中间层的声波在小隔间中反复反射,由于反射声波的重叠振幅而导致能量分散和能量平衡,最终被消除。 在通过刚性消声中间层进入弹性消音底层的任何残留低频声波的情况下,它们在底层中进一步消除。

    • An acoustically significant composite panel having a general sound-absorbing face (or a general sound-diffusing face) and a tuned sound-absorbing face. Such a panel includes a sandwich or composite of a first layer of molding media, a honeycomb of cells and a second layer of molding media. The first layer has at least one or more apertures in it that convert the corresponding cells into Helmholtz resonators. These Helmholtz resonators can be tuned to the same or different frequencies. The second layer is generally sound-absorbing. A general diffuser structure can be attached to the second layer. These panels can be attached to the walls and/or ceilings of a room to control its sonic quality. Also, these panels can be suspended vertically below a ceiling to control noise.
    • 一种声学重要的复合面板,具有一般的吸音面(或一般的声音扩散面)和调谐的吸音面。 这种面板包括第一层成型介质,蜂窝单元和第二层模制介质的夹层或复合材料。 第一层具有至少一个或多个孔,其将相应的单元转换成亥姆霍兹共振器。 这些亥姆霍兹谐振器可以调谐到相同或不同的频率。 第二层通常是吸音。 一般的扩散器结构可附接到第二层。 这些面板可以连接到房间的墙壁和/或天花板上,以控制其声音质量。 此外,这些面板可以垂直悬挂在天花板下方,以控制噪音。

    • An acoustical insulation panel to absorb and attenuate sound energy comprising an inner core including a plurality of cells formed therein and an outer membrane disposed on each side of the inner core to cooperatively form a plurality of sound attenuating chambers, each outer membrane includes an inner substrate of nonwoven meltblown microfiber acoustical absorbing fabric extending into each of the plurality of cells to cooperatively form the corresponding sound attenuating chamber therebetween and an outer facing to protect the corresponding inner substrate of nonwoven meltblown microfiber acoustical absorbing fabric.
