strange sound from iPhone 6 speaker

Can anyone test this. Put your iPhone 6 to your ear so that the speaker is as close to the ear as possible, now power up the display. can you hear a strange sound? Power down, up display with sleep/wake button a few times while keeping it to your ear speaker facing the ear. WTF.

Yep, I hear it. But only when my phone is that close to my ear and it's quiet in the room and there's no other noise coming from my iPhone 6.
I can't hear it when it's just sat there in front of me or I'm using it looking at the screen, so I'm not gonna worry about this one too much.
Most electrical devices have some noise coming from them when they're on, displays especially.

Probably, but my other iPhones and iPads don't have it.
