All chargers make a low buzzing noise if you listen carefully.

But if this is pretty loud and it's only just started I'd replace it if you can. Faulty chargers cause fires and it's just not worth the risk imho.

I tend to get Anker stuff these days as they last really well: https://www.amazon.co.uk/s/ref=nb_sb...+charger+anker

Other than that I'd just get an official one.

That is odd. I've heard of power adapters humming before (caused by a loose or faulty transformer), but that's a low 50Hz tone rather than a high pitched noise.
You could try percussive therapy (hitting it), but don't hold me responsible if you break it!

Chances are it's your charger - you might be able to convince the apple people to replace it but I don't imagine they'll be able to hear the noise as over time, a person's hearing deterioates and they can't hear the higher pitched sounds so you'll be best off talking to a younger assisstant at the store to try and get them to help...

lol my external hard drive used to do this... dunno if it still does but it was only after I unplugged it that it started doing it. Strange; very high-pitched sound anyway.

I used to be able to do something like that. Often heard monitors/TVs when they were on standby.

seriously, high pitch noise could mean one thing, electricity surge/leak, dont touch it if you don't want to die,i suggest to buy another one asap and get off the laptop!

Lol, I 'hear' some chargers as well. My phone charger makes a really quiet, high pitched sound and no one else can hear it apart from me!! I know it's there because when I turn the charger off the sound goes!

It's because you are a 'child' and can hear higher pitched sounds. Haven't you ever heard of that children only ring tone? :p:

Does it happen if you use it in a different location? Could be a polarity problemb local to room or building.
Needs a plug checker to test socket as a starting point to diagnose.
