隔音罩的结构有哪些

时间:2018-11-09浏览次数:348


   隔音罩又称为隔音间、隔声房等,为了防止(fáng zhǐ)外界噪声入侵(指以征服或虏掠为目的的窜犯),在噪声强烈的局部(part)环境(environment)空间内建造隔声性能良好的小室,形成安静的小室或房间,对工作人员的听力进行保护,这种隔音设施叫做隔音罩。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。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。隔音罩不但要考虑(consider)隔声性能,还要考虑到观察方便、出入方便、不影响车间内正常运输、以及房间内供电、通风等。一般隔音罩外墙用隔声性能较好的材料(Material)或结构(Structure),如砖、混凝(coagulation)土、纸面石膏板墙等,观察部分使用(use)隔声窗,进出部分使用隔声门或吸声通道等。隔声间墙内一般较多使用隔音材料,如穿孔吸声板吊顶、软包墙面(qiáng miàn)、以及吊挂空间吸声体等。
