摘要
为了探究不同声压级条件下车内噪声对乘客乘坐舒适性的影响规律,需要建立高速列车客室噪声模拟系统。分析了模拟系统中声源布置合理性及其模拟系统的组成,说明了基于等效声压级的噪声模拟数据的处理方法与软件编写,并进行了系统的软件和硬件测试与分析。该系统能够实现各种声压级噪声数据的动态模拟与声音回放,达到了试验需求的设计目的。
In order to study the influence of different noise levels on the riding comfort of highspeed train,the noise simulation system is designed and realized in this paper. Firstly,the sound resource arrangement is discussed and the consisting components of the noise simulation system are introduced. The data processing method based on the equivalent sound press level is analyzed and its software system is developed. The different press level noises can be simulated and played back after the simulation test of hardware and software,which can meet the requirements of noise simulation experiment.
