Description

Technical field[0001]The present invention relates to the field of automotive noise reduction, particularly a plasma-based automotive noise reduction system and method.Background technique[0002]With the rapid development of the automobile industry, the requirements of car manufacturers and consumers have become higher and higher, and the main source of automotive noise is engine noise, transmission system noise, tire pavement noise, and aerodynamic noise. Relevant research points to that when the vehicle speed exceeds 100km / h, pneumatic noise has become the main contribution source of automotive noise, which is an important factor affecting ride comfort. Automotive pneumatic noise can be divided into air noise and intravaver noise in the car. High-speed traveling automobiles and airflow interacts, forming a boundary layer, body exterior attachment, and slit in the surface of the body, making the boundary layer produces a powerful separation stream, and then attached to the turbule...
