将介绍单个和多个MPEG第3层编码的音频质量的几个测量结果。进行了主观和客观测试。客观差异等级（ODG）和主观差异等级（SDG）的分数之间的比较证明了PEAQ方法在更高的比特率下更准确。基于ITU建议的LAME编码器和PEAQ软件的最新版本已与ITU标准一起用于执行小损伤的主观测试。
The results of several measurements of audio quality of single and multiple MPEG-Layer 3 encodings will be presented. Subjective and objective tests have been done. A comparisons between the scores of the objective difference grade (ODG) and the subjective difference grade (SDG) prove a more accuracy of the PEAQ method at higher bit-rate. The recent versions of the LAME encoder and PEAQ software based on the ITU recommendation have been used, in association with the ITU standards for the execution of the Subjective test for small impairments.
