Electrical Buzzing noise coming from Studio Display

It is very annoying, I wouldn't bother with all this otherwise.
Apple has closed the case but I reopened just for one last attempt. Unfortunately, given my locality, I don't think I'll find qualified electrical folks who can take a look at the situation but I'll try mentioning it and see what suggestions I get. Re-wiring the house is a difficult thing but I'll see if there's a way to isolate it once I get the device back.
I'm still not going to let Apple off the hook, will try every legal route I can. I just find it unacceptable that a product sold at this price, under warranty, has these problems and they just slide it aside saying it's "normal".
Really? That was now also my last hope
You might still find power condition/electrical hum exterminator options which are available and relatively affordable there so do research (and given that you have such generous refund policies, you should try). I couldn't find any Indian outlet compatible power condition/hum eliminators that are affordable. Most are 1/2 the price of the ASD or higher and most don't support Indian outlets.
Even if I were to hypothetically end up buying one of them, there's no guarantee it'll fix the issue.
Do keep us posted, would love in case they have some suggestions and in case you do end up with a proper fix, let us know (besides the iPhone thing).
One crazy aspect about all of this, is the fact that as I wrote -- the same buzz happens on my Mac Studio (a different device but probably a similar PSU engineering), and follows the same patterns as you kept on updating. What do you drive your Studio display with may I ask? I don't have a Studio Display. Also I'll check on the iPhone observation you have mentioned soon.
Just checking -- the buzz can happen even without any computer connected to the studio display, right? For me a power cable connection (and a powered on device lol) is enough.
Yes, I will keep you updated here. I hope that I will quickly find a solution
Yes, the buzzing also occurs when the ASD is not connected to a device.
I use a Mac Mini M1 2020 and a Mac Studio. With both the buzzing comes. When I just plug in my MacBook, there is no buzzing, but as soon as the MacBook gets warmer, the buzzing starts here as well.
Currently, I have an old iPhone XS Max connected and the buzzing stops. I'll leave that on until I find another solution. ;D
Could you record a video of what the Mac Studio sounds like? Mine also makes noise, but is drowned out by the ASD ...
Yes, but has been not as loud as when something is plugged in, like my MBP16.
Would you look at that, someone from the Philippines uploaded the EXACT buzzing sound scenario I’m facing with the AC to YouTube yesterday!
(starts at 0:41)
His electric buzzing is louder than mine, but I also don't have air conditioning, just 24/7 ventilation systems in the apartment.
I will also try a condition/electrical hum exterminator and test it out.
But surely, it can't be the ASD anymore? Because I now have my third ASD that has such problems.
But we all have one thing in common: An air conditioner / ventilation system in the apartment and an ASD which causes buzzing.
I mean, this is the only device in my house since we moved in that has this issue, apart from a very cheap set of speakers I used in the 2010s but even that didn't buzz quite as much as the ASD. So, I have to reject the idea that it's the house or the air conditioner that's the culprit. I mean, sure, the electrical interference caused might be higher in my house wiring since it's been 23 years since construction completed but again, these devices are supposed to be designed to not have these issues. I have bookshelf speakers that are 1/15th the price of ASD which are working perfectly—I figure speakers are usually a lot more sensitive to these things.
I have the same issue in my house. Everything else is fine - but the ASD was buzzy. It's clearly an engineering/design issue with the ASD and will likely never be solved.
Tomorrow an electrician will come by and look at the situation. I hope he can find the cause of why the ASD is buzzing.
The only option we have: Ask for money back and wait for the new ASD Pro, which is supposed to be released in Q1/2023 (according to leakers).
The electrician was with me today and has looked at everything.
Actually, at the sockets should arrive maximum only 230v, but with mine come 241v - 245v. Since I live on the first floor, I get of course the full power and those above me live, of course, the normal 230v ... :-/
Directly under my apartment is also the technical room for the power in the house.
However, the ASD is designed only to max 240v. In the upper apartments, the ASD makes no problems....

Have you guys measured your power at the outlet?

Very interesting. I wonder how can this explain the increased buzzing noise while an AC is on or for me an electric car is being charged (there are noises regardless but it gets louder). From my check the voltage doesn't change at all when those are on (still high at like ~243).
In my case, I can say that my ASD did not make any buzzing noises in the Apple Store and also with friends.
Also my other devices, such as the WMF toaster, Phillips Hue lamps and the Telekom router give a buzzing noise ...
The ASD can, as previously mentioned, a maximum of 240v. Any volt above that makes the ASD buzz. Higher current voltage fluctuations will also cause this.
My ps5 also started buzzing when I moved to the new house, but my hue lamps don't make buzzing noises (whereas not smart bulbs do). In case of ASD they still screwed up with it, because my lg oled tv is also designed for 100-240 V, but it is absolutely silent.
Not necessarily over 240 V. I have 238 V in the morning, and ASD is buzzing. Once I caught 235 V in my outlets, and ASD still did buzzing noise, but it was significantly quieter, almost unnoticeable
Yes. A tolerance of like 5% is supposed to be standard from a quick check now online. I'll measure the voltage at a friend's house. Again, I still think there's more to it because the AC/ car charger makes the buzzing worse at the same voltage (so why is the buzzing getting worse in this setting?). Also I have more Apple devices with the same 240V AC max rating, probably just like you, meaning their PSU design for the Studio is specially bad. Thank you for updating. My guess is that the problem has something to do with voltage and interference togehter.
