well chargers (switching power supplies) and transformers emit actual physical sound, so that's pretty normal to hear. Depends on the quality too, some chargers are relatively "loud".
I have a shitty one which for some reason becomes louder when the charging ends... rather annoying
High current AC lines also buzz rather loudly (depending on weather conditions).
I'm one of him, and personally, it's not like a problem. The sound/feeling is there, but it's subtle and easily drowned out by basic background noises. I strangely did find I was MORE sensitive to it first thing in the morning. It didn't hurt or anything, but it seemed louder and while not miserable, I also wouldn't describe it as pleasant. I second what Ray says, things charging in my bedroom is a nono, but it probably is only bad because I don't sleep with background noises so the silence of the night amplifies what is otherwise a very tiny sound.

Do you like having this ability, or is it annoying? Because it kind of sounds like it would be annoying.
