What sound insulation material should be used for hotel doors?

The sound insulation of the floor needs vibration isolation.

If it's just sound insulation, you can choose super quiet fragrance. The construction of this thing is relatively simple, and it won't do too much engineering and damage. You can move in immediately after the construction is completed. Basically everything is ready (furniture removed, floor tiles removed) and can be completed in one day. The disadvantage is that only the ground is made, which can not reduce vibration and has limited sound insulation effect.

The other is to choose the sound insulation and vibration reduction series of Dr. Sheng Company, which can not only reduce the sound transmission, but also prevent the vibration from spreading to the downstairs to form a new noise source.

The third is to lay carpets directly at home. Soft materials with long hair can reduce the noise caused by the impact between the ground and the sole, which is also very good. However, the price of carpets is high, and snacks are needed for matching styles. In addition, cleaning is more troublesome.
