摘要：

针对汽车内饰环境,提出利用声学模拟软件EASE进行车载扬声器声场混响时间仿真的方法,指导车辆内饰设计,提高工作效率。为验证EASE软件仿真的准确性,分别通过EASE软件和电声测试系统CLIO进行某型国产轿车车载扬声器声场混响时间研究。结果显示:混响时间测量曲线与EASE仿真曲线吻合良好,EASE软件的仿真结果准确可靠。

Abstract: A method was proposed to guide the design of interior trim and improve the work efficiency in the interior trim environment, in which the reverberation time in vehicular speaker sound field was simulated by acoustic simulation software EASE. Through the software EASE and the electro-acoustic test system CLIO, the research of reverberation time was conducted separately in the domestic car of a certain type to verify the accuracy of simulation. The results demonstrated that curves obtained by two methods mentioned above were in good agreement, and the simulation result was accurate and reliable.
