摘要

主观评估或听力测试一直是音频设备评估的重要组成部分，今天可能更加重要。对于某些类型的数字音频设备，没有适当的客观测量方法。对于高级比特率降低系统来说，这当然是正确的。因此，主观评价在选择数字音频广播(DAB)的源编码算法时起着非常重要的作用。

Subjective Assessments Of Low Bit-rate Audio Codecs

Subjective assessments or listening tests have always been an important part in the evaluation of audio equipment, maybe even more so today. For certain types of digital audio equipment there are no adequate methods of objective measurements available. This is certainly true for advanced bitrate reduction systems. Subjective assessments therefore play a very important role in the choice of a source coding algorithm for DAB, Digital Audio Broadcasting.
