What is the main purpose of a silent room

Silent room is a noise control measure that uses sound insulation components to cover the noise source in a smaller space, reducing the transmission of noise. The shape of the soundproof room is often designed to be close to the outline of the sound source, and installed as close to the sound source as possible to reduce its volume and lower the cost. The application of sound-absorbing soundproof rooms is quite wide, and various sound source equipment such as fans and water pumps will be used for sound source control. Its main design principle is to effectively control the noise source from the propagation path of sound waves. Due to the different external dimensions, ventilation and heat dissipation requirements of each sound source device, it often needs to be designed, processed and produced according to the on-site sound source situation.

To ensure sufficient sound insulation, soundproof rooms generally use metal materials such as 0.5-2mm galvanized steel plates and aluminum plates. Sometimes, 3-5mm damping coating materials are required on the inner walls to reduce resonance or standing wave phenomena of these metal outer walls; In the soundproof room, the inner layer of the wall is mostly composed of perforated panels covered with sound-absorbing materials, or directly pasted with some polyester sound-absorbing materials. The principle of a soundproof room is to enclose the noise source in a small space to reduce its external radiated noise as a protective structure. Therefore, the overall structure of the soundproof room must be designed according to the structure of the sound source equipment, and there is no particularly fixed shape or structure.

Generally speaking, composite structures with light weight and good sound insulation performance are required for design, and sound-absorbing linings with high sound absorption coefficients must also be added to soundproof rooms!
