移动终端音频测试平台的建设

The Building of Test Platform for Mobile Terminal Audio

通话是移动终端最基本的功能,而音频质量是否优良直接影响到了通话质量。对音频指标进行准确的客观测试是保证通话质量的前提。精确的测试平台和准确的测试方法是客观测试的基础。测试平台的搭建需要考虑以下方面的客观测量与主观评测的符合性、仪器的精度要求和校准方法、系统的准确性和再现性、测试方法的可操作性,另外还要考虑系统的兼容性和可升级性,综合以上各种需求后经过方案设计、设备选型和系统调试后就可以进行测试和验证。

To communicate is the most basic function of mobile terminals and the audio quality directly influences the communication quality. An accurate objective test on audio indicator is the premise to ensure the quality of communication. A precise test platform and accurate test method is the basis for an objective testing. The building of a test platform needs to consider the following aspects： compliance between the objective measuring and subjective evaluation, accuracy requirements and the calibration methods of the instruments, the accuracy and reproducibility of system, the operability of testing methods, as well as the compatibility and scalability of the system. Taking the above requirements into consideration, we can carry out the testing and certifying after programme design, equipment selection and system debugging.
