Recently, with profound accumulation in acoustic engineering, standardized project delivery system and strict quality control, Guangzhou DP Artificial Environment Technology Co., Ltd. has successfully won the bid for the acoustic laboratory construction project of SGS, a globally authoritative third-party testing and certification institution. The project involves the construction of three core acoustic test spaces, namely airborne sound insulation room, impact sound insulation room and reverberation room, helping SGS upgrade its acoustic testing infrastructure and strengthen its capability for high-precision noise and sound insulation measurement.

   Originating from Switzerland, SGS is a century-old world-renowned institution. Founded in Geneva in 1878 and listed on the SIX Swiss Exchange, it has built global credibility in quality testing services. Its brand promise reads “When you need to be sure”. Through over a century of global expansion, SGS operates across 115 countries, with more than 2,500 laboratories and branches and over 100,000 professional technicians, forming a worldwide standardized network for testing, inspection and certification. In 1991, SGS entered China and established its joint venture SGS-CSTC. It has set up standardized laboratories in many major domestic cities to deliver localized one-stop technical services.

   As a benchmark player in the global TIC industry, SGS’s core businesses cover testing, inspection and certification, serving consumer goods, industrial environment, natural resources, food & health, supply chain audit and other sectors. Its Industry & Environment division specializes in noise and vibration testing, material performance evaluation and environmental safety assessment. In the field of building element sound insulation and product acoustic performance testing, it adopts stringent requirements and world-class acceptance criteria for acoustic laboratories in terms of spatial precision, background noise, sound insulation, reverberation indicators and construction workmanship.

   Winning this general contract for SGS’s acoustic laboratory project is dual recognition from this internationally authoritative testing body for the enterprise’s technical strength, project execution capability and overall service quality. It fully demonstrates Guangzhou DP Artificial Environment Technology Co., Ltd.’s professionalism and market reputation in high-end acoustic laboratory engineering.

   Guangzhou DP Anechoic T&E Co.,Ltd.is composed of a group of domestic and foreign acoustic experts and professional engineers who have been engaged in various acoustic technology research for many years and have rich theoretical and practical experience. It has its own office buildings and factories, and the factory has acoustic laboratories in line with CNAS standards, which can monitor the acoustic technical indicators of its own products and carry out acoustic testing services. Through the hard work and continuous innovation and development of Danpin team, the acoustics laboratory designed, produced and installed by Danpin has products with accurate technical indicators, green environmental protection, durable quality, beautiful appearance and high scientific and technological content.GZ DC Acoustic Technology Research Co., Ltd., an affiliated company of GZ DP, is a high - tech company specialized in the research and development of acoustic testing instruments. The acoustic environment provided by DP can be perfectly and seamlessly integrated with the testing instruments of DC. Therefore, it can offer a complete solution for acoustic laboratories.
