Warm congratulations on the successful acceptance check of the anechoic chamber for the automotive scale model wind tunnel constructed by our company for Chongqing University of Technology.

Summary: GZ DP Anechoic T&E?Co., Ltd. is composed of a team of acoustic experts and professional engineers who have been engaged in various acoustic technology researches at home and abroad for many years and have rich theoretical and practical experience. It has its own office buildings and factories. An acoustic laboratory that meets the CNAS standards has been built in the factory, which can monitor the acoustic technical indicators of its own products and provide external acoustic testing services. The semi-anechoic chamber is not only a special laboratory for acoustic testing but also an important part of the testing system. In fact, it is also one of the acoustic testing equipment, and its acoustic performance indicators directly affect the testing accuracy. For the detailed acoustic design, manufacturing, construction, installation, on-site measurement and acceptance introduction and other follow-up materials of anechoic chambers, dead rooms, quiet rooms, reverberation rooms, semi-anechoic chambers, semi-dead rooms, fully anechoic chambers and fully dead rooms, please pay attention to browsing the project cases on the official website of our company or scan the QR code of the WeChat public service account of our company to get free push notifications. For the detailed information of anechoic chambers, dead rooms, quiet rooms, reverberation rooms, semi-anechoic chambers, semi-dead rooms, fully anechoic chambers and fully dead rooms, please go to the download center on the official website of our company to download for free.
