  隔音房海南七星彩论坛小编今天讲讲噪音(分贝(dB))的分类(Classification),噪声是紊乱(chaos)、断续或统计上随机的声振动(vibration)。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。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。噪声的强度(strength)通常用级来表示,单位是分贝(dB)。
