摘　　要：研究现有声品质评价方法,开发一套集声音数据可视化管理、声品质主要评价参数计算、声品质主观评价打分及评价结果自动处理为一体的声品质评价系统,并应用该系统进行稳态车内噪声评价实验,证明了系统的正确性和工程应用价值。It develops a system for sound quality evaluating supported by the studies of current sound quality evaluation. The system is composed of sound data visualization management, calculation of main parameters contributing to sound quality, marking based on subjective assessment and auto-process for the results. Furthermore ,the system has been applied to carry out the car interior noise evaluation experiment. Finally,the system has been proved to possess high accuracy and engineering application value.
