  静音房小编今天为大家总结了关于噪音(分贝(dB))的知识(Knowledge),一起来了解吧。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;隔音房是一种为有测试要求的产品制造车间设计的隔声测试装置,在隔声间内进行吸声处理,使其成为一个小型的无声室,在里面可测试一些小型的产品,如精密仪器、电机、音响、变压器等。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。从物理上解释:噪声是声源做无规则振动(vibration)时发出的声音,声音由物体振动引起,以波的形式在一定的介质(起决定作用(role)的物质)(如固体、液体、气体(gases))中进行传播。我们平时听到的声音主要是空气声,一般情况(Condition)下,人的耳朵可以听到的声波频率(frequency)是20-20000HZ左右,称为可听声;而低于20HZ,称为次声波;高于20000HZ,称为超声波(是一种频率高于20000赫兹的声波)。
