Project introduction: The noise generated by the operation of Yutong bus workshop, including grinding, stamping, shearing and other processes, has a large scope of operation, and there are many noise points, mutual influence and interference. In order to solve the problem of reducing mutual interference and emissions, the NCC Shenzhen team provided workshop noise research, testing and regional planning and design, divided the environment according to different operating processes, and designed and applied process noise barriers for treatment. It achieves local absorption and regional isolation of noise, and minimizes the mutual influence and interference of noise. Get great results.
