1, noise-free classroom design can use sound insulation board and some mute materials. Quiet is very necessary for the classroom, because people's reading and working efficiency is much lower in a noisy environment than in a quiet environment. Therefore, this principle should be implemented in classroom decoration from material selection to decoration construction.

2. Noisy classroom decoration can start from the ceiling. In order to make the ceiling soundproof, some soundproof plates are mainly used on the ceiling keel and gypsum board. There are mainly three kinds of sound insulation materials: glass sound insulation cotton, high-density foam board and fabric sound absorption board. These three materials are different in function and price. Relatively speaking, the construction technology of glass sound insulation cotton and fabric sound insulation board is relatively simple, and the sound insulation effect is good, while the construction of high-density foam board is a little more troublesome, but the effect is good.

3, the ground quiet decoration can choose cork floor, carpet. Silent cork floor can improve the elasticity index and static bending strength of the floor, so that the floor has the function of sound absorption and sound insulation. Carpet for floor mute: Because of its tight and breathable structure, it can absorb and isolate sound waves and has good sound absorption and sound insulation effect.
