现在的隔音门一般分两种，一种就是像tata那种，在木门四周贴上一圈密封条，以紧密贴合门框的方式，较少木门缝隙，从而达到隔音的效果。还有一种就是像双虎木门那样，在门底安装自动升降式密封条，以密封门底缝隙的方法，从而达到隔音效果。相比下来后者密封的缝隙更大，效果应该较好一些。

There are generally two types of soundproof doors. One is the kind like Tata. A circle of seals is affixed around the wooden door. In a way that closely fits the door frame, there are fewer gaps in the wooden door to achieve sound insulation. Another is to install an automatic lifting seal on the bottom of the door like a double Tiger wood door to seal the crack at the bottom of the door so as to achieve sound insulation. Compared with the latter seal the gap is bigger, the effect should be better.
