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 an acoustic laboratory 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.
Semi-anechoic chamber is not only a special laboratory for acoustic testing, but also an important part of the test system, in fact, it is also one of the acoustic testing equipment, and its acoustic performance indicators directly affect the accuracy of the test.For follow-up information such as specific acoustic design, manufacturing, construction and installation, and brief introduction of site measurement and acceptance, please pay attention to visit the project case on the official website, or scan the QR code of the wechat public service number to get a free push, and for detailed information, please go to the download center of the official website for free download.
