很多培训班教室设置在商场，或者大型培训中心，周边有很多商户或者其他同行，上课的声音会互相干扰，或是被其他商户投诉。这样就需要在装修的时候考虑隔音的问题，避免串音干扰。隔音主要考虑培训教室房间的六个面，墙面、天花、地面、门窗隔音。
一、墙面隔音
墙面包含建筑原墙面和新建隔墙，原建筑隔墙一般比较厚重，隔音效果比较好，就不需要再做特别处理。室内新建的隔墙就隔音会比较差，需要做隔音处理。常见的室内隔墙有三种，石膏板隔墙、玻璃隔墙、轻质砖隔墙。
1 石膏板隔墙的隔音处理，在龙骨之间放隔音棉，然后在龙骨表面铺贴隔音毡，然后在安装石膏板。
2 轻质砖隔墙的隔音处理，在墙的表面安装龙骨，龙骨之间填充隔音棉，表面再安装石膏板或者装饰板。
3 玻璃隔墙的隔音处理比较简单，只需要做双层玻璃即可达到比较好的隔音效果。
墙面减震隔音
二、天花隔音
天花吊顶一般采用轻钢龙骨石膏板吊顶，可以在轻钢龙骨上面铺上隔音毡，然后再安装石膏板。
三、地面隔音
地面如果铺地毯或者铺复合地板，可以现在地面铺一层隔音毡。
四、门窗隔音
门窗尽量使用密封性比较好的类型，门框有隔音条的比较好，地弹簧玻璃门由于周边都有缝隙，隔音会很差。窗户玻璃可采用双层中空玻璃。
以上就是信欣装饰公司在装修培训教室的时采用的一些隔音方法，完工后测试隔音效果还可以，但是相对比影院、音乐厅等场所的隔音还是有一些差距。
