Why is the famous house in Gongcheng, Lu 'an so bad? The sound insulation is not good, and you can hear snoring next door.

You can hear the snoring of the wall, indicating that the wall is made of light materials, such as foam bricks, aerated blocks or hollow slatted walls.

Now the houses are mostly frame structures, and the walls are mostly non-bearing walls, and the sound insulation effect of non-bearing walls is very poor;

Second, because houses are not for sale, developers can save money in the process of building houses. If they can cut corners, they will cut corners. No problem is strange!
