When driving on the road, the road noise usually affects people's driving experience. Recently, Harman international, the audio manufacturer, has released the road noise active noise reduction technology (ranc) for mass production vehicles, which can effectively reduce the road noise received when driving. It is reported that this technology is jointly developed by Harman international and automobile, so it will also take the lead in realizing mass production of the modern automobile sub brand denises. Geniseth will be equipped with the ranc technology in its gv80 model, which is also the first mass production model equipped with the technology. The model is also equipped with other technologies within the Harman halosonic sound management solution suite, focusing on the vehicle intelligent network. In the live broadcast of the 54th "super bowl" (NFL Major League Championship of the year), denises showed the new SUV gv80 to audiences from all over the world. It can be seen that great expectations are placed on it. It is reported that the advertising cost of "super bowl" is as high as 5.6 million US dollars (about 39.17 million yuan) every 30 seconds. According to the plan of modern automobile, Denis is expected to enter the Chinese market formally in 2020, and the gv80 just released in January will become the key to whether Denis can be based on the Chinese market. For a long time, automobile manufacturers have been trying their best to meet the needs of users for fuel economy, suspension firmness and other aspects of the vehicle. The above measures will cause unnecessary noise between vehicle structures, and eventually lead to "buzz" in the vehicle cockpit, which is easy to cause driving distraction and increase the fatigue of drivers. In addition, road noise can also cause interference to the driver in the vehicle. If the traditional passive noise control method is used to reduce the above noise, the weight of the car body will be increased, and the fuel economy and carbon dioxide emissions will also be adversely affected. The ranc technology jointly developed by Harman international and Hyundai Automobile can send out sound waves to the noise transmitted to the cabin, and realize the active and real-time noise reduction effect without changing the weight of the car body. After six years of research and development, Hyundai has been ready to mass produce the ranc technology. In the near future, we will be able to experience the active noise reduction technology of road noise on the genesiss gv80 (parameter | inquiry).
