ETSI TR 102 949研究了新的感知激励参数，这些参数更紧密地定义了音频质量，例如 对于宽带和超宽带语音，用户感知的语音的响度、保真度和可懂度 终端。附件详细研究了接收信号的响度，具体取决于传输带宽、编解码器、， 传输信号的类型，并比较不同计算模型的结果。本文件旨在提供可供选择的或新的质量参数和试验方法 按照相关标准和规范执行。

ETSI TR 102 949 investigates new perceptually motivated parameters defining more closely the audio quality, such as loudness, fidelity and intelligibility of the speech as perceived by the user, for wideband and superwideband speech terminals.The annexes detail studies about loudness of received signals, depending on the transmission bandwidths, the codecs, the types of transmitted signals and compare results from different computation models.The intention of the present document is to provide alternative or new quality parameters and test methods to be implemented in the relevant standards and specifications.
