摘要：
Vehicle interior noise control is one of the most important research areas in vehicle noise, vibration and harshness (NVH). Conventional passive noise control technology is very effective for medium and high frequency noise (higher than 500 Hz), but ineffective for low frequency noise. Active noise control (ANC), base on destructive interference, is suitable for controlling low frequency noise and has been adopted as standard configuration by the whole series of many mass production vehicle models. So far researchers in academia concentrate on developing new algorithms and optimizing their performance mainly while the report on the effect of active noise control in industry is one-sided and there is little detailed measurement results published on ANC system installed in mass production vehicle. In order to provide reference for academic research and more detailed information about the actual effect of active noise control system to car makers, the performance and robustness of the ANC system installed in a commercial vehicle are tested when the car is stationary and running, respectively. Experiment results show that the ANC system has good control of the engine noise and good robustness. © 2019, Society of Automotive Engineers of China. All right reserved.
