There are complaints on Twitter, Reddit and the Apple Assist Group relationship again to June, and extra lately on the MacRumors boards, in regards to the concern, which is variously described as an “electrical buzzing” and “fixed ringing” that’s “loud,” “high-pitched,” and “very annoying.”

A number of homeowners have discovered that the sound isn’t fan-related and solely occurs when a MacBook Professional or iPad is plugged into the Studio Display. Some have additionally famous that the noise can fluctuate in depth and pitch relying on the time of day, suggesting {an electrical} shielding concern will be the trigger of the fault.

From Apple Assist Group member Ryan Roberts:

“I am experiencing a really annoying high-pitched buzzing sound with my Studio Display, I’ve spoken to others on Twitter who even have the issue and I’ve had Apple help on the case however nothing was resolved.


“It isn’t the followers, it is a distinct (and really annoying) sound that emanates from the rear space of the show, roughly the place the ability provide is positioned.

“I am 90% sure the show is selecting up interference from someplace and amplifying it, possibly by means of the home energy circuit however I can not ensure. Somebody I spoke to believes the PSU is poorly shielded however I don’t know if that is true both.”

Some customers have steered the ‌Apple Studio Display‌ picks up interference from electrical automotive chargers. Within the case of MacRumors reader Indominus, they tracked the supply of the interference again to Lutron Caseta mild dimmers which might be put in of their home.

“At any time when the dimmer is turned on, the buzzing noise begins popping out from the ASD. The dimmers usually are not even on the identical breaker as my ASD. The one factor I can suppose of is that the dimmers are creating electrical noise that’s propagating to {the electrical} panel which then propagates to the ASD.

Now it is one factor that the dimmers are creating electrical noise. However it’s one other factor that solely the ASD is reacting to this noise. I do not hear this electrical noise popping out of another factor in my home. It seems to be a problem with the ASD energy provide. Whether or not it is an issue with the particular show I’ve or the selection of parts within the design of the ASD energy provide, I have no idea.

MacRumors reader uller6 relayed an analogous expertise:

“I had the identical concern sadly. I spent a pair hours on the cellphone with Apple help/engineering, and we got here to the very same conclusion you probably did: the ASD is poorly shielded towards soiled RF line noise, which is propagated by means of the ability provide to the fan management circuit, producing an audible buzz. In my case operating my air con on a unique circuit triggered the ASD to buzz loudly. I ended up returning my show and haven’t bought one other.”

Different customers say they’ve tried electrical energy filters to resolve the problem however to no avail, and a few have acquired a number of substitute items from Apple that have been equally affected.

It isn’t clear how widespread the problem is, however Apple seems to remember of the issue affecting some Studio Display homeowners, though an answer has not but been discovered. It is price noting that this can be a separate Studio Display concern to the widespread speaker drawback that Apple finally fastened with a firmware replace. Have you ever discovered the show to be over-sensitive to electrical interference? Tell us within the feedback.
