Overview: Chongqing University of Technology, abbreviated as CQUT, is located in Chongqing, a municipality directly under the central government. It is a member of the China Ordnance Collaborative Innovation Alliance, an ordinary undergraduate institution jointly built by the central and local governments, a key university under construction in Chongqing, an implementing university of the national college students innovation and entrepreneurship training program, a university with typical employment experience for national graduates, one of the first batch of universities for the transformation and technology transfer of scientific and technological achievements, and an selected university for the first batch of new engineering research and practice projects of the Ministry of Education.
The school traces its origins back to the No. 11 Technical School of the Ordnance Department of the National Government established in 1940. After 1950, the school was renamed successively as the Industrial Vocational School of the 21st Arsenal, the Industrial School of the Southwest Industrial Department of the Southwest Military and Political Commission, Chongqing Machinery Industry School, the Southwest First Industrial School of the Second Ministry of Machinery Industry, Chongqing Industrial School, Chongqing Machinery Manufacturing Industry School, Chongqing First Machinery Manufacturing Industry School, Chongqing Institute of Technology, and Chongqing Institute of Industrial Management. In 1999, it was transferred to the management of Chongqing Municipality by China Ordnance Industry Corporation and renamed Chongqing Institute of Technology. In 2001, Chongqing Economic Management Cadre College was incorporated as a whole. In 2009, it was renamed Chongqing University of Technology with the approval of the Ministry of Education.
The anechoic chamber of the wind tunnel (anechoic chamber, silent chamber, reverberation chamber, semi-anechoic chamber, semi-silent chamber, full-anechoic chamber, full-silent 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 equipments, and its acoustic performance indicators directly affect the testing accuracy. For simple introductions to the specific acoustic design, manufacturing, construction, installation, and on-site actual measurement and acceptance of anechoic chambers, silent chambers, etc., please pay attention to browsing the project cases on our official website, or scan the QR code of our WeChat public service account for free push.
