The NVH lab phase Ⅱ was inaugurated on April 19, 2016. The test building is 24m high with 4 floors. It covers an area of 3112m2 and the total construction area is 10,291 m2. It has 11 laboratories with seven acoustic test functions, and the total investment of facilities is 120 million RMB. The lab incorporates advantages such as efficient development, climate simulation, energy conservation and environmental protection, which helps to meet the test requirements of various frequency noise during the development process of vehicle, subsystems and parts. With this lab, the test function of acoustic development of PATAC is multidimensional expanded, and it marks that the mute technology and vehicle development of SGM and PATAC reaches a new height.
