| 摘 要： | 以ITU—RBS．1387—1为基础，讨论了多种音频质量客观评价的改进方法。在此基础上提出了“对各种改进方法加以综合，可进一步提高相关度系数”的假设。结合国、内外相关文献，进行了试验性地优化，最终实现了可视化仿真程序OE（Objective Evaluation）设计，主、客观评价相关度达到了0．85以上。

| Abstract: | This paper discusses several modified methods for objective audio quality assessment based on ITU-R BS.1387-1, and the Recommendation is implemented by our visual emluator OE (Objective Evaluation). The OE optimizes the Recommendation by integrating the modified methods mentioned above. The correlation coefficient between the subjective and objective assessments is up to 0.85. |
