    • Certain example embodiments relate to an acoustic wall assembly that uses active sound reverberation to achieve noise-disruptive functionality, and/or a method of making and/or using the same. With the active approach, sound waves in a given frequency range are detected by a sound masking circuit. Responsive to detection of such sound waves, an air pump (e.g., speaker) is used to pump air in the wall assembly to actively mask the detected sound waves via reverberation and/or the like. The wall assembly may include one, two, or more walls, and the walls may be partial or full walls. A passive approach may also be used additionally to the active approach. With the passive approach, sound waves in a given frequency range are disrupted via features (e.g., holes, slits, etc.) formed in and/or on a wall itself.
    • 某些示例实施例涉及使用主动声音混响来实现噪声破坏性功能的声学墙组件,和/或制作和/或使用其的方法。 采用主动方法,声音掩蔽电路可检测给定频率范围内的声波。 响应于这种声波的检测,使用气泵(例如,扬声器)来泵送壁组件中的空气以通过混响等主动地掩蔽所检测到的声波。 墙壁组件可以包括一个,两个或更多个墙壁,并且墙壁可以是部分或全部墙壁。 主动方法还可以使用被动方法。 采用被动方法时,在给定频率范围内的声波通过形成在墙壁和/或墙壁本身上的特征(例如,孔,狭缝等)被破坏。
