Centro听筒音质的专业测试文章

在网上找到一篇关于Palm Centro的评测，摘录声音部分的片段。
We use professional audio testing hardware and software to test the quality of audio produced and received by the Palm Centro. To simulate the human ear and mouth we used a Head and Torso Simulator (HATS), and to analyze the sound sent and received by the phone we used an electro-acoustic analysis program SoundCheck. This is the same combination used by many handset manufacturers. For more details on how we test see this article.

8 S; O4 X. Z5 T* ISound Receive Frequency Response (7.82)

  i) [5 U  v( |" G7 g1 I, Y! WAbove is a graph of the quality of sound received by the Palm Centro. This is how you hear others during a phone call. The blue line indicates the Centro's performance, while the two red lines are the limits against which we test. An ideal handset's curve would run right between these limits. As you can see, the Centro's performance on this test was a little off, rising above our limits at the lower end and falling off a little too quickly. This can lead to exaggerated lower frequencies (making voices sound boomy). But this is only a minor problem;  the sound quality of voices received over the Centro is pretty good.

以上是Palm Centro接收声音的曲线图，也就是你在通话中听到别人的声音。蓝色线是Centro的性能，上下两条红线是我们测试中的阀值线。理想的手机曲线应该在两条红线的中央位置。可以看到, 本次测试中Centro的性能有一点点不理想，在低音端，超过了我们的上限，而在高音端下降太快。这就导致夸大了低音效果（使声音听起来有点闷），但是这仅仅是一个小问题，通过Centro接收到的声音听起来音质还是相当好的。

查了查Boomy这个词的解释: 【声学】 低沉有回响的：在回音中表现出过多的低调重音的）

就是感觉声音跟其他的手机有点不一样。。。

死老妖

这能说明什么问题呢？测试机的Fireware版本都不知道，好像

而且好像还是cdma的，因为测得是sprint的
