The paper, which is based on the "Research and Development of the Speed-up Train"s Manipulation of Optimization and Train Simulator project, concerns the sound system in the Train Simulator. In the paper, the sound system includes two parts contents: firstly, improving the sound effect of the sound simulation system in the Train Simulator and enhancing 3D sound effect, such as sense of distance, sense of orientation, Doppler Effect etc, to make the sound of training environment more verisimilar; secondly, realization of the speech communication in network between teacher and student in the Train Simulator.

本文是以铁道部科技发展项目"提速列车优化操纵与机车仿真器研究开发"为依托，对机车仿真器的声音系统进行研究：第一，对机车仿真器中声音仿真系统的音效进行改进，增加3D音效，如声音的距离感、方位感、多普勒效应等，使得训练环境音响更加逼真；第二，实现机车仿真器中教员与学员间的语音网络通讯。
