[0008] Furthermore, the panels include: fiber cement pressure boards, cement pressure boards, water glass pressure boards, calcium silicate boards, silicate boards, calcium silicate boards, metal boards, gypsum boards, and magnesium cement boards. The magnesium cement boards are made of magnesium oxide and magnesium salts plus aggregates, filling materials and auxiliary materials. The magnesium salts include magnesium chloride, magnesium sulfate, and magnesium phosphate, or a combination of two or more thereof.

[0009] Furthermore, the panel may be provided with hollowing.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The core layer of the utility model adopts a thermal insulation board or a composite thermal insulation board design, which can effectively isolate sound waves while keeping warm. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] 2. The hollow design of the panel of the utility model can absorb sound and reduce and weaken the propagation of sound.
