How to deal with wall sound insulation when installing home theater or private theater in hotel rooms, so as not to affect the rest next door.

First of all, if it is a gypsum board wall, it needs sound insulation and sound absorption. If it is a solid wall, the problem of sound insulation and absorption can be completely avoided on the premise of selecting professional equipment. Some professional hotel audio-visual solutions (note that I am talking about hotel audio-visual solutions, and there are few speakers in this direction at present) are directional sound designs, and low frequencies generally do not directly touch the ground and walls to prevent the vibration from spreading. In addition, the intelligent tuning system in the background is very important. Choosing a professional scheme can save a lot of engineering costs. In this regard, Ying Chao Hotel is still doing very well.
