Why is the hotel soundproof better than home?

This is because hotels, in order to make a good reputation, it is very necessary to achieve a very quiet environment indoors, so many hotels use Dev soundproof doors and windows to control outdoor noise and spread it indoors. So when you stay in the hotel, you will find many doors and windows like this, and most hotels are carpeted, which has a certain attraction and will also prevent the banging from upstairs from spreading to the downstairs. The glass wool interlayer is placed in the wall, so it also has a good inhibitory effect on the spread of this noise between the walls, which is why the sound insulation of the hotel is better than that of the home.
