还是前面的ha2-se VS ipad pro 9.7耳机口最大音量输出qq音乐**对比的。这个看数据好像区别更大?不过没前面那么容易听出来...
Trial 1, user: B actual: B 1/1
Trial 2, user: B actual: B 2/2
Trial 3, user: A actual: A 3/3
Trial 4, user: B actual: B 4/4
Trial 5, user: A actual: A 5/5
Probability of guessing: 3.1%
A=Reference,B=Comparison
Test type: ABX
就前1秒区别最大的那段才明显,oppo声音厚实一些,ipad声音薄,后面就难分辨了。不过听多了容易疲劳,歇会再听好像更容易分辨...
歇了会又听的:
Trial 1, user: B actual: B 1/1
Trial 2, user: B actual: B 2/2
Trial 3, user: A actual: A 3/3
Probability of guessing: 12.5%
A=Reference,B=Comparison
Test type: ABX
这次听的区别比较小的人声部分,信心不太足,就测了3次,不过居然也全对了...技巧就是这次oppo 暗一些干净一些声音好似小一些,ipad更亮...
