Analysis of vehicle NVH noise reduction technology

With the rise of new energy vehicles, the NVH (noise, vibration and harshness) performance of the whole vehicle has become one of the important indicators for measuring the quality of the vehicle. Major automobile brands have invested in research and development to seek more effective noise reduction solutions. For example, models such as Tesla Model S and Audi e-tron have effectively reduced the noise level in the car by adopting advanced sound insulation materials and suspension systems. In addition, some technology companies such as Bose are also providing customized audio systems for cars to reduce the impact of external noise on driving and riding. The application of these technologies not only improves driving comfort, but also brings new development opportunities to the new energy vehicle market.
