Hello, our friends from media This is the NVH Laboratory of EXEED NVH refers to noise, vibration and harshness of the vehicle NVH performance is a key indicator for evaluating the driving and riding comfort, and an important basis for evaluating the quality of a vehicle In this laboratory, we did a lot of pre-tests and adjustments, and even compared our NVH with that of some leading brands Our only goal is to offer every user the high-end experience with the best sound quality This is the vehicle 4WD semi-anechoic chamber This chamber is for controlling the NVH quality of a vehicle, which is of great significance Now let's have a test The background noise of the whole chamber is 19 D B A, almost equivalent to the stillness in the dead of night How quite is it? In such a large chamber, how can we make it so quiet? Firstly, we use customized acoustic wedges in the whole chamber to absorb sound waves The whole chamber has a room-in-room structure, that is, there are hundreds of load-bearing springs under the chamber A larger room is outside the chamber, providing a shock-absorbing effect At the center of the chamber, there is a silent hub introduced from AVL For only this chamber, the construction cost is as high as CNY 50 million In addition, our NVH Laboratory also includes vehicle semi-anechoic chamber, sound quality evaluation chamber, modal laboratory, sealing laboratory, subsystem semi-anechoic chamber, sound insulation laboratory and BSR laboratory, These 8 laboratories cost a total investment of about CNY 200 million, leading in China and even in Asia Thanks to such excellent hardwares, EXEED is confident to provide every user with library-level quiet cockpits You may ask why does the anechoic chamber have to be so quiet? That is because only in a relatively quiet space can we ensure the stability of the test environment, and improve and control the NVH performance of vehicles based on the collected data Noise control is not just to thicken the sound insulation cotton, but to involve the NVH adjustment of the vehicle Next, through two tests, let's experience the excellent noise control of EXEED Before the test, all microphones shall be calibrated with professional equipment While the test equipment on the market, such as decibel meters, are not precise enough The main position of our test is the outer ear of the driver seat and the right outer ear of the second row You may notice that after the EXEED is started, the noise in the vehicle is stable at 39 D B A This is already much better than the high-end models of many joint ventures At the same time, we also tested the noise in the vehicle at a constant speed of 60km/h, 80km/h and 120km/h. All the tests have very good results The laboratory is just a tool, and we still need to put people first A high-end product is not just to lower the noise below 39 D B A after starting, but to make the driving and riding an aural pleasure In addition to a comfortable driving and riding experience, safety is of dominant significance for high-end models Next, please welcome my colleague to show our friends from media around the Crash Laboratory of EXEED to understand how EXEED protects the safety of our users and their families
