iPhone 6S/6S Plus 耳機孔噪音災情 Noisegate/噪音門

記得老主板的聲音輸出噪音嗎? 使用的CPU有嗡嗡的噪音?

iPhone 6S/6S Plus 看起來也有 (確定在測試中手機耳機聲音大小是'靜音')

This video is a comparison of the electrical noise produced over the headphone jack during activity on both the iPhone 5S and iPhone 6S.
It demonstrates that my iPhone 6S has significantly poorer isolation from processing noise than my previous iPhone. I have confirmed that this noise is present on other iPhone 6S / 6S Plus units and is not specific to my unit. I do not know if this is an issue related to a particular batch of iPhone 6S units.

Some other users have observed the noise and some have not. It may
depends on the sensitivity of your earphones at the particular frequencies of the noise. It can only be heard in a quiet room.

I have noticed the noise on the following earphones:

- Audio Technica ATH-IM02 (36 ohms, 113dB)
- Nuforce Primo 8 (38 ohms, 118dB)
- Sony MDR-7550 (16 ohms, 108dB)
- Sony XBA-C10 (24 ohms, 100dB)
- VSonic VSD3S (40 ohms, 108dB)

這表明，我的iPhone6S已經從比我以前的iPhone的處理噪音顯著稍差的隔離。我已經證實，該噪聲是存在於其他iPhone6S/6S加上單位和不是特定於我的單元。我不知道這是關係到一個特定批次的iPhone6S單位的問題。

其他一些用戶已經觀測到的噪聲，有些則沒有。它可能
