Sound facilities, mainly unit soundproof rooms (covers). The so-called unitized soundproof room (hood) is usually first composed of prefabricated soundproof panels such as wall panels and bottom panels, and then each panel part is connected and installed by fasteners at the equipment site to achieve the effect of sound insulation. At present, most of the sound insulation boards are made of alloy plates and aluminum thin plates packaged with sound-absorbing materials. The sound absorption and sound insulation effects are limited, and the cost is relatively high. Moreover, the aluminum plates are easily corroded and affect the service life. Stainless steel has excellent characteristics such as unique strength, high wear resistance, superior anti-corrosion performance, and not easy to rust. It is also often used to make sound insulation panels, but the sound insulation effect of pure stainless steel panels is not ideal.

General objects have sound insulation effect, but we only call the board with the average sound insulation (in an infinite space, an infinite material between the sound source and the measured point) more than 30dB as a sound insulation board. Sound insulation panels are generally high-density materials.

However, in the prior art, the effect of sound-absorbing and sound-insulating building wall panels is often not good, and it is difficult to achieve the claimed effect. A large part of it is because the panels only pay attention to one aspect of noise prevention and shock absorption, while ignoring the other. On the one hand, therefore, there is a need for a noise-proof, shock-absorbing and sound-insulating wallboard to solve the above-mentioned problems.
