  噪声是紊乱(chaos)、断续或统计上随机的声振动(vibration)。测试隔音房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。噪声的强度(strength)通常用级来表示,单位是分贝(dB)。那么噪音(分贝(dB))都是怎么分类(Classification)的隔音房小编接下来为您介绍。
