I want to open a mid- to low-end hotel. What material should be used for room partitions that has better sound insulation effect?

No matter how low-end a hotel is, it must be well soundproofed, otherwise it will be difficult to get repeat customers.

The effect of using bricks to build a wall is indeed better than that of gypsum board, but the prerequisite is that it reaches a certain thickness, at least 240mm thick, plus double-sided plastering, leveling, putty and paint, not to mention the high cost. It takes up a lot of space.

At present, the partition walls of budget hotels such as Home Inn, Hanting Hotel, Jinjiang Inn, etc. generally use this structure (as shown in the picture). If you want to reduce the cost, you can replace the "high-density soundproof wallboard" in the picture with 12mm thick gypsum board.
