摘要： PURPOSE: A semi-active sound absorbing system, and an absorbing method using the same are provided to maximize absorbing performance by absorbing noise according to a change of frequency. CONSTITUTION: A semi-active sound absorbing system comprises a porous sound absorbing panel(10), expansion support devices(20), a noise input device(31), and an expansion control device(30). The porous sound absorbing panel is installed separating from the front surface of a wall(12) for forming a rear air layer(13) between the wall and the porous sound absorbing panel. The expansion support devices are installed between the porous sound absorbing panel and the wall. And the expansion support devices are expanded so that the thickness of the rear air layer is changed. Noise is inputted to the noise input device. The expansion control device analyzes a frequency of the noise transferred from the noise input device, and generates an expansion or contraction signal of the expansion support devices according to the analyzed result.
摘要翻译：目的：提供一种半主动式吸音系统及使用其的吸收方法，以通过根据频率变化吸收噪音来最大化吸收性能。构成：半主动吸音系统包括多孔吸声板（10），膨胀支撑装置（20），噪声输入装置（31）和膨胀控制装置（30）。所述多孔吸声板与所述壁和所述多孔吸音板之间形成后空气层（13）的壁（12）的前表面分离地安装。膨胀支撑装置安装在多孔吸音板和墙壁之间。膨胀支撑装置被膨胀，使后空气层的厚度发生变化。噪声被输入到噪声输入装置。扩展控制装置分析从噪声输入装置传送的噪声的频率，并根据分析结果生成扩展支持装置的扩展或收缩信号。
