Absorbers with controllable charact

Absorbers with controllable characteristics were also investigated. Both a controllable high frequency absorber and a controllable low frequency absorber were designed. The low frequency unit had good absorption below 100 hz but was of rather massive construction and had to be sealed to the room surface on which it was mounted.

避震器与可控特点也进行了调查。高频可控减振器和可控低频率减振器的目的。低频率单位有良好吸收 100 hz 以下但相当庞大的建筑，不得不将密封室表面，它被装入到。

吸收剂具有可控特性进行了研究。两个可控的高频吸收器和一个可控的低频吸收器的设计。低频单元有低于100赫兹吸收好，但相当大规模的建设而不得不被密封在它被安装在房间面。

还研究了可控性吸收剂。一个可控的高频器和一个可控低频减振器的设计。低频单元具有良好的吸收低于100赫兹，但相当大规模的建设，必须密封房间表面上正被安装。
