The silent cabin is a special acoustic room with a low-decibel indoor environment. It is a kind of laboratory. It is mainly used to test the sound volume and to isolate strong environmental noise to establish a quiet working environment for use. Such as: office, lounge, telephone booth, reading room, interview, sleep, piano room, etc.
The materials used in the silent cabin are all sound-absorbing and sound-insulating materials with good sound absorption and sound insulation performance. They are generally composed of steel plates, sound insulation boards, shock-absorbing and damping materials, keel main frames, fireproof filter cloths, interior metal microporous sound-absorbing layers, etc.; the background noise of the silent cabin is below 45dB, and the common value is between 45-20dB, which is specifically designed according to the sound volume of the test product or according to meeting environmental requirements.
The silent cabin is generally divided into fixed, movable, detachable, template assembly, etc. Under normal circumstances, the silent cabin is made into a fixed type, and the fixed silent cabin has a lower production cost than other types. Fixed silent cabin: It is installed in a fixed place and cannot be moved. Its advantages are long service life, firmness, beauty, and convenience of production. Its disadvantage is that it can only be used in a fixed place. Movable silent cabin: Pulleys will be added under the silent cabin to facilitate movement. However, due to the large size and weight of the silent cabin, it is generally not made into a mobile type. A small soundproof box is equivalent to a mobile silent cabin, which has the characteristics of small size, beautiful shape, light weight, sound insulation effect, and easy movement. Detachable (module assembly) silent cabin: The detachable silent cabin is mainly for later relocation and reuse, which provides a higher utilization rate, but the cost of the detachable silent cabin is about 30% higher than that of the ordinary silent cabin.
