很多培訓班教室設置在商場，或者大型培訓中心，周邊有很多商戶或者其他同行，上課的聲音會互相干擾，或是被其他商戶投訴。這樣就需要在裝修的時候考慮隔音的問題，避免串音干擾。隔音主要考慮培訓教室房間的六個面，墻面、天花、地面、門窗隔音。
一、墻面隔音
墻面包含建筑原墻面和新建隔墻，原建筑隔墻一般比較厚重，隔音效果比較好，就不需要再做特別處理。室內新建的隔墻就隔音會比較差，需要做隔音處理。常見的室內隔墻有三種，石膏板隔墻、玻璃隔墻、輕質磚隔墻。
1 石膏板隔墻的隔音處理，在龍骨之間放隔音棉，然后在龍骨表面鋪貼隔音氈，然后在安裝石膏板。
2 輕質磚隔墻的隔音處理，在墻的表面安裝龍骨，龍骨之間填充隔音棉，表面再安裝石膏板或者裝飾板。
3 玻璃隔墻的隔音處理比較簡單，只需要做雙層玻璃即可達到比較好的隔音效果。
?墻面減震隔音
二、天花隔音
天花吊頂一般采用輕鋼龍骨石膏板吊頂，可以在輕鋼龍骨上面鋪上隔音氈，然后再安裝石膏板。
三、地面隔音
地面如果鋪地毯或者鋪復合地板，可以現在地面鋪一層隔音氈。
四、門窗隔音
門窗盡量使用密封性比較好的類型，門框有隔音條的比較好，地彈簧玻璃門由于周邊都有縫隙，隔音會很差。窗戶玻璃可采用雙層中空玻璃。
以上就是信欣裝飾公司在裝修培訓教室的時采用的一些隔音方法，完工后測試隔音效果還可以，但是相對比影院、音樂廳等場所的隔音還是有一些差距。
