The acoustic environmental requirements for whole-vehicle noise testing according to the ISO 362, ECE R51, and GB 1495-2002 standards are introduced. Referring to the national and international standards such as GB 6882-1986 and ISO 3745-2003 and considering the requirements in actual usage, some indexes of the whole vehicle’s semi-anechoic chamber construction are proposed for the National Automobile Quality Supervision Test Center (NAQSTC) in Xiangfan. The laboratory for the testing in the NAQSTC has been appraised by China’s Institute of Metrology. The detail of the design, construction and the appraisement of the whole vehicle semi-anechoic chamber is introduced.
