    • Acoustic construction element comprising sound insulating cavities having a constant shape along an axis parallel to the exposed surface of the construction element, at least part of said cavities comprising a first portion, situated closest to the external surface of the element, having a smaller width than the maximum width of a second, internal portion of the cavity, of which: - at least part of said cavities have different depths; - at least part of said cavities have different internal volumes and/or different internal shapes; - at least part of said cavities have a substantially constant width over their entire depth; - and at least part of said cavities are completely or partially filled with sound insulating material.
    • 声学构造元件包括沿平行于构造元件的暴露表面的轴线具有恒定形状的隔音腔,所述空腔的至少一部分包括位于最靠近元件的外表面的第一部分,该第一部分的宽度比 空腔的第二内部部分的最大宽度,其中:至少部分所述空腔具有不同的深度; - 所述腔的至少一部分具有不同的内部体积和/或不同的内部形状; - 所述腔的至少一部分在其整个深度上具有基本恒定的宽度; 并且所述空腔的至少一部分被隔音材料完全或部分地填充。
