The sound of the cinema allows users to enjoy a better audio-visual effect, but it also makes the theater need to spend a lot of money to deal with the sound insulation between the different halls. And in this play a key role in the product is the movie theater soundproof door, they are generally made of special materials, and sealing reliable, open flexible, so can play a very good sound insulation effect. Then today with the editor to understand a few manufacturers suitable for the acquisition of soundproof doors.
First, the movie theater soundproof door manufacturers recommended
1, Shanghai Chen Key Industry Co. complete and scientific quality management system.

The company has passed ISO9002 international quality system certification in 2000. Its products are exported to all over the country, and exported to Europe, America, Mongolia, New Zealand, Russia, India, and Africa and other more than 20 countries and regions.
Beijing Dafushi Industry and Trade Co., Ltd. is one of the few joint-stock enterprises in the industry that specializes in the design, production, sales and installation of explosion-proof doors and windows, explosion-discharge doors and windows, radiation-proof doors and windows, bullet-proof doors, acoustic doors, industrial doors, prison doors, and other series of products.
3, Beijing five plus Chuangzhan special doors and windows Co., Ltd., is a research and development and sales and integration of diversified special doors and windows enterprises, the company is located in the emerging manufacturing center of Beijing Shunyi District, the company has excellent management personnel and strong technical force, the technical level of personnel with a high starting point, professional and focused, the construction team of strong organizational discipline, high technical qualities, experienced in actual operation, the establishment of quality assurance system, and pre-sales, sales, and the installation of radiation doors and windows, bulletproof doors, soundproof doors, industrial doors, prison doors and other series of products. Quality assurance system, and pre-sale, sale, after-sale perfect management system for strict requirements, so the construction of the project are good design effect, qualified product quality, considerate service has won the community and customers a wide range of praise.
Two, the movie theater soundproof door requirements
Sound insulation index 30dB, 35dB, 40dB, 45dB (A) four
Look at the flatness of the door, the flatter the door, the better the combination with the door set, China's indoor acoustic standard index of 22 to 25 decibels, that is, the door must be resisted at least 20 decibels of noise.
Acoustic doors are mainly used in high sound insulation requirements of the sound insulation role, door molding is mainly used in new galvanized steel, the internal use of professional soundproofing materials, sound damping panels, acoustic cotton and other soundproof filler, at the same time, the most important soundproof door sealing treatment. The use of magnetic sealing can ensure a good sealing sound insulation effect.
Soundproof door has the following characteristics using multi-layer composite, special sound insulation structure, and can withstand high temperature and pneumatic load. The soundproof door is divided into single door and double door, of which the single door sound insulation effect will be obviously better than the double door sound insulation effect. And can be with observation window, reliable sealing, opening flexible. Professional soundproof door production basically will not take the push-pull structure, push-pull type is not conducive to the sealing process, will greatly affect the overall effect of sound insulation.
According to the different use of the environment and its sound insulation design requirements are different. The higher the decibel value, the higher the sound insulation performance.
The above recommended three manufacturers suitable for the acquisition of soundproof doors without exception have excellent technical advantages, but also a good hand in the production of windows and doors. And their soundproof doors because of cost-effective, reliable quality and can be used in many areas, some can even be exported to other countries, so there is no direction in the purchase of friends can consider these three enterprises. In addition to the requirements of the soundproof door, we also carried out the example, you can learn that the different coefficients of sound insulation corresponding to the requirements will be different.
