What material is used for the partition wall of the dance classroom? Good sound insulation effect and low cost.

Of course, the effect is proportional to the price. If the effect is good, use a sound insulation board. In fact, at the end of this period, many manufacturers of sound insulation materials are more favorable. I have heard of some outdoor large-scale sound insulation projects, mostly indoors. If possible, consider using sound insulation boards on both sides as partitions. Of course, it is also possible to use gypsum board outside the double-layer sound insulation felt, which is also very economical ~
