Shanghai Chi Engineering Company Limited (hereinafter referred to as "Shanghai Chi") was established in Shanghai to provide noise and vibration measurement, quantitative analysis and design, product processing, installation, testing, perfect service system. Equipped with the most advanced computer-aided design, computer-aided manufacturing systems, product quality, projects across the country, and the southeast coast of the central and western regions noise control projects to provide technical support, and commitment to new product research, development and manufacturing, low-cost, high-performance to meet the needs of different customers.

       Chi Construction in Shanghai since its inception, and constantly improve the acoustic environment and the Habitat efforts and using software, hardware, equipment, training of professional and technical personnel. Domestic companies have excellent acoustics engineers and senior professional and technical acoustic consultants, with rich experiences in the engineering practice, the different acoustic environment of the most reasonable solution, according to the scene terrain acoustic environment simulation assessment. Shanghai Chi engineers have been involved in building the light rail Wuhan, Guangzhou, loops, Wando Shenzhen Expressway, Shanghai GM plant, unified enterprise Food Factory, Honeywell (China), Sujiahang Expressway, Suzhou, East Central Viaduct, Suzhou South Central Viaduct, Nanjing Metro, the Hong Kong Kowloon-Canton Railway and other large noise in the design of projects and construction of rail transit, highways, viaducts and factory equipment to resolve the noise had extensive experience.

       Chi Shanghai Construction Engineering and the Chinese Academy of Sciences Institute of Acoustics, Acoustic Research Institute of Tongji University, Shanghai Academy of Sciences, and other environmental and scientific research units to maintain long-term cooperation and technical exchanges and acoustic noise and is committed to a solution to the problem of the integration of the characteristics of modern architecture and landscape Design concept, so as to solve the noise problem into modern urban construction style. Gradually with the development of urban transport to the track, the development trend of high-altitude traffic, Chi Sound Engineering gradually introduced high-performance, security, aesthetics, urban development requirements for the various types of noise reduction products.

       How types of companies noise control products, a significant Muffler, acoustic, noise, vibration isolation performance, and after laboratory testing. The standard models are:

Noise barriers noise gate
 
Tongfengchuang acoustic-acoustic enclosures
 
Muffler blinds pipeline muffler
 
Industrial silencer muffler, the noise Room
 
Impedance composite muffler microperforated acoustic board
 

       Shanghai Chi Construction products primarily to the following four areas: A) road noise barriers: If highway or high-speed railway barriers, running the airport road barriers. B) General Noise Control: Air conditioning pipes, generator room, pump room, the air compressor, such as condensing unit. C) Architectural Acoustics: songs theaters, television and radio studio, multi-purpose conference room, sports venues, such as the voice test. D) anti-vibration damping categories: anti-vibration performance requirements of high construction, noise and vibration to avoid high-performance requirements, such as installation of mechanical equipment. The technology company in a professional, reasonable fees to help domestic and foreign users to deal with the noise.

       Product quality and service reputation is built in Shanghai Chi decorated for the purpose of the consistent, sincerely hopes that with the industry, to establish a long-term friendly cooperation. If you have noise control problems and the demand for products, and all the agents of the company or link, we will be happy to provide you with the most complete services.
