Abstract
The audio system is the core component of the vehicle’s active sound design and active noise reduction. In order to analyze the acoustic characteristics of audio system, it is necessary to use simulation to study its frequency response and the propagation characteristics of the sound field in the vehicle. Due to the wide frequency coverage of the frequency response, full band coverage cannot be achieved using a single simulation method. Traditional sound field simulation can only cover the frequency band below 1 000 Hz by using finite element methods. To solve this problem, Ray tracing method commonly used in architectural acoustics was introduced into this study. The scope of application of ray tracing method applicable to the sound field in the vehicle was discussed. Finally, the audio system was modeled and analyzed based on the ray-tracing method, the influencing factors of the results were analyzed. It is pointed out that factors such as high frequency leakage, sound transmission of glass and sound source directivity affect the simulation results.
