基于“粒子算法”的汽车主动声效设计

Vehicle Active Sound Design based on the “Granule Algorithm”

为提升用户的听觉体验,文章提出了汽车主动声效控制及其实现方法。主动声效系统以车辆运行参数为输入,通过声效系统实时生成调用音频源文件,最后经由车载扬声器等转换为可听声。通过实际装车评价,主动声效系统可实时跟随车辆运行状态变化,与车辆本体声音融合无突兀感,提升了驾乘过程的“声趣”感受。

In this paper,the vehicle active sound control and the realization method is put forward in order to improve the customers′driving experience.Using vehicle operation parameters as the input,the sound source files are generated by the active sound system,and then convert to sound through vehicle speakers.The actual loading evaluates that the active sound system change with vehicle status in real time,and the sound of the vehicle body is not ambiguous,which enhances the fun of sound feeling while driving.
