前天刚买iphone 7 plus玫瑰金，第一次看到这消息也抖抖的
想说我是不是中标了，查了一些资讯，这应该是叫做coil whine
目前看到这个网站的文章有做过比较多的比较测试，给大家参考看看

No, hisses and buzzes aren't unique to iPhone 7 and aren't a problem
不!!这种滋滋声不是iphone 7才有的，而且这不是一个问题。
First, it was iPhone 7 Home buttons and capacitive gloves, now it's iPhone 7
making a "hiss" or "buzz" sound. Every year, the tidal wave that is iPhone
launch attention sweeps up all sorts of "gates" in its wake, and it can be
difficult and confusing to sort the real from the imagined.
首先，是"iphone 7 的Home键与电容触控手套 (可参考原连结另外一篇文章)"，现在
是iphone 7会发出滋滋杂音，每年新iphone发表总会有各类"门"的话题产生
会让人搞不清楚哪些是真的问题那些是想像出来的。
We've now spent almost a day testing both iPhone 7 and iPhone 7 Plus, as well
as the last two generations of iPhone, all recent iPads, recent Macs,
peripherals like routers, and other electronic devices. And here's the deal:
我们花了一整天测试iphone 7跟iphone 7 plus,还有最近二代的iphone，所有最近的
iPad,最近的Macs，一些周边设备像是路由器，或其他电子装置，结论是:
They all make the same noises, and all to differing degrees. I initially
thought iPhone 7 Plus might be louder, but after putting a series of devices
through high-intensity CPU/GPU activity, which pulls much more power than
normal daily use, they all sounded roughly the same. That includes the
MacBook Pro I'm typing this on right now.
他们都产生同样的噪音，而且程度都不一样，我本来以为iPhone 7 Plus会比较大声
但是如果让所有装置都处在比日常使用还要高CPU/GPU强度的状态下
也就是消耗更多的电力，他们听起来就都差不多吵
包含我正在打这篇文章的MacBook Pro
It also makes sense, given the people who noticed the noise did so while
their new iPhones were restoring, which migrates libraries, re-indexes data,
and otherwise puts the system through heavy load.
这样的测试结果也算合理，一开始人们开始注意到这件事情是拿到新的iphone
然后还原系统，手机忙着整合函式库，重新索引资料，因此系统处于高负载状态
Since many people have now reported hearing the same sound from other devices
across a wide range consumer electronics and brands, and hardware engineers
around the internet have commented and tweeted explaining what the sound is
and why it's not only normal but expected, it seems highly likely nothing out
of the ordinary is going on. (I'd say "almost certainly", but I try not to
mistake my writing for an engineering degree!)
这种噪音其实在其他的消费性电子产品也可以听到，硬件工程师也在网络上有很多说明
这种现象对电子产品来说几乎是再正常不过了。 (我会说"几乎确定"，但我尽量
使用工程师的专业来精准描述)
Perhaps there's something about the new iPhones that makes the sound louder
and more noticeable, or perhaps it's because everyone is hyper-vigilant
following the Galaxy Note 7 recall.
Regardless, there doesn't seem to be anything to be concerned about, not with
the processors, the batteries, nor the radios. So go back to setting up your
new iPhones, and enjoy!
可能因为新的iphone才会让这种现象被放大或是被注意到，或是因为大家对于Note 7的
召回事件而过度警觉了。
总之，不用过度担心，处理器、电池、无线电都没问题，好好享受你的新iphone吧。
