摘要
为了保证手机的音频性能符合测试标准,使用户对手机通话语音的发送和接收质量感到满意,同时还要保证手机扬声器的语音不能对使用者,尤其是对人耳造成伤害,因此就要对手机的各项语音性能进行检验,保证手机的音频电路的质量和工作正常。探讨了使用R&S公司的音频测试系统、3GPP TS26.132测试规范对手机进行测试的测试项目和测试方法,分析了不同音频测试标准的区别。并提出一些解决音频测试失败项的方法,经验表明这些方法是非常有效的。
In order to guarantee that the audio performance of mobile phone meets the test specification, make the user satisfied with the transmission and receiving audio quality of mobile phone, and make the voice of speaker not cause the damage to users, particularly to their ears, the examination of each mobile phone audio perfomance must be carried out to guarantee the quality of audio circuit and its normal work. The test items and methods had been discussed when audio testing was carried out with R＆S audio test system and 3GPP TS26.132 test specification, and the difference of different audio specification had also been analyzed. Meanwhile some methods that can solute failed audio test cases were proposed. The experience indicates these methods are very effective.
