  隔声罩的整体结构(Structure)必须根据声源设备(shèbèi)的结构进行设计(Design),并没有特别固定的外形或结构。测试隔音房海南七星彩论坛隔音房主体结构为防震框架型,采用模块式拼装,方便安装和拆卸。主体采用方型钢为骨架,外侧板采用环保型优质玻璃钢板做面板;内侧采用多孔铝板,采用优质的吸音棉、隔音材料和阻尼涂料,使有效吸叫噪声音,提高低频噪音降噪效果;测试隔音房用途:用于各类电子机械元件静音测试等,房外80分贝,房内20±1分贝,有防水、防火、稳固等特点。其具体规格要求可选。流水线隔音房隔音效果:外界75dB,内部40dB,尺寸根据要求定制。流水线可从房内通过,不影响测试效果。隔音房分类:隔音房按声学性能分为消声/消音系列、静音系列、隔音系列、屏蔽系列。一般来说需要设计时采用质轻、隔声性能(xìng néng)好的复合(recombination)结构,隔音罩内也必须附加吸声系数高的吸声内衬等等。根据一些特殊设备的工作(job)特性(characteristic]),也会采用如隔振器、双层密封(seal)结构、带通风口结构、加隔音材料(Material)的通风管结构、刚性密封结构等等。
