昨天試試錄影功能發現，在安靜的環境下錄影
竟然會出現很大聲的嘶嘶~轟隆~啪次的噪音，很像迎著風錄音的那種風切聲
上網查國外不少人有同樣的問題，但是國內好像沒人討論過，難道因為16G版比較正常 ?
請問跟我一樣使用32G的網友們有發現一樣的問題嗎 ?

新聞<Nexus 5降噪缺陷被曝 背景噪音如八级大风>
來源連結來源連結
谷歌 Nexus 系列手机一直以来都是超低价加上超高配置的代表，正因为如此，该系列机子已经成为多数谷歌粉丝心中的超高性价比之作，而且机子的抢购风潮从 Nexus 4 开始就从未停歇。但是，Nexus 5 也有不完美的一面，很多用户发现这款机子实际上存在着很多琐碎的毛病，比如通话音频质量问题。
威锋网 11 月 29 日消息，近日，有不少 Nexus 5 用户反馈，他们在通话和录音过程中，受到了一系列的音频问题，该问题被反馈到了 AndroidPolice 网站上，并且同时抱怨该问题的用户不少。据称，Nexus 5 的麦克风在收录声音时会出现嘶嘶声、爆裂声、不明噪音，或者时不时音量变得非常低。
具体来说，当用户在进行通话时，通话声音变得十分小，有些用户将音量调到最大仍无法听清楚对方的的声音，而且通话中还伴有嘶嘶声。而当使用录音时，录制的效果相当不理想，可以清晰地听到背景中不明噪音，甚至有用户表示这种背景噪音类似于顶着八级大风通话，即便 Google Now 也无法进行识别。
有一些细心的用户通过研究和分析后表示，出现这些问题的根本原因在于 Nexus 5 智能手机的内部降噪软件。因为，当他们在不开启降噪功能的情况下，录音时根本不会表现出如此令人失望的症状。
比较遗憾的是，目前还没有针对此问题的修复方案，不过如果真的是降噪软件惹的祸，相信谷歌肯定会发布更新修复这一问题，至于具体何时只能后续保持关注了。如果非要通过物理的方式解决有两种方式，第一种是将降噪麦克风封起来，第二种是使用有线控的耳机或者蓝牙无线耳机。

We've all heard the story before. A brand new, very popular device rolls out to the public and everybody hurries to get their hands on it. Shortly thereafter, people start to notice some of the more serious issues that degrade the experience or even make the gadget unusable. When that device is a phone and one of those issues is audio quality during calls and recordings, people can become justifiably angry. It seems this is exactly what's happening with quite a few Nexus 5 owners, as audio going into the built-in microphone is plagued by hissing, popping, loud static, and very low volume.

Symptoms
Like many of the Bug Watches lately, the symptoms aren't completely consistent for everybody. In fact, it's likely that we're talking about a few separate issues that might be playing off of each other, so not all handsets will be affected in quite the same way. Simply put, phone calls and many applications on the Nexus 5 are getting extremely low quality audio. Most people became suspicious when an app like SoundHound is unable to recognize music or Google Now can't understand clearly spoken commands. During phone calls, many of the people affected by this issue are told that they sound like the phone might be really far away or that their voices sound garbled, perhaps even cutting out. When audio or video is recorded on the Nexus 5, the results can often be really uneven, filled with static or hissing, or just not loud enough to hear.
The issues seem to affect phone calls and recordings in almost all reported cases. It's likely most regular apps are also affected, but the degree may not always be enough to interrupt normal function. Strangely, there are very mixed results when the speakerphone is used or calls are made with VoIP apps, suggesting that these things might be accessing sound in ways that don't invoke the issue.
Check out the videos below for sample recordings from some affected devices. Warning, the static-filled video on the left is particularly loud while the hissing video on the right is fairly quiet, be sure to adjust your volume accordingly.
