Metal sound barrier or cement sound barrier, which has better sound insulation effect?

Both metal sound barrier and cement sound barrier have good sound insulation effect, but which one is better depends on the specific use environment and demand.

Metal sound barriers are usually composed of metal plates and thermal insulation materials, which can effectively reflect sound waves, and thermal insulation materials can absorb and isolate sound waves. Metal sound barrier has the advantages of fire prevention, corrosion resistance, weather resistance and so on, and it is not easy to age and has a long service life.

Cement sound barrier is composed of cement board and sound insulation cotton. The density of cement board is high, which can effectively inhibit the propagation of sound waves, while the sound insulation cotton can absorb and isolate sound waves. Cement sound barrier is suitable for places that need high sound insulation requirements, such as urban roads, highways, airports, railways and so on.

Therefore, in the specific application, it is necessary to choose the appropriate sound barrier according to the actual situation. If it needs to be used for a long time, and it requires durability, fire prevention, etc. Then the metal sound barrier is a good choice; If you need a higher sound insulation effect, you can choose a cement sound barrier.
