Why do transformers make a humming noise?
video description
If the plates have been interlinked/tightened together properly and coated correctly with lacquer there shouldn't be much noise.
Older transformers generally hum more because the lacquer have cracked over the years due to the expansion/contraction/movement of the plates which then allows them to resonate more.
The bolts, screws, rivets or whatever technique that was used to fixate the plates might also have become undone causing the same effect.
The volume of the hum will depend on the load of the transformer since a greater load will create a stronger electro magnetic force acting upon it.

Can someone please tell me what to do about a transformer hum in my apartment that is too loud. I dont know where exactly it is but the sound is throughout. I try drowning it at bedtime with white noise but am tired of that. I wont be able to move for a yr at the least least as Im a senior citizen on apt. waiting lists.
This seems unhealthy and illegal. Im one of the best tenants there is but management sucks. they avoid issues often and wont help. The head manager initially said he couldnt hear it and basically that he couldnt respond to something if he cant hear it then another time said he cant hear it because his hearing is bad.

Oh, thank you! I never thought to ask this, but I am glad you answered it anyway lmao
But if we were to add a cooling mechanism to the transformer, would we be able to prevent some iron or copper loss? Or would adding something like that either take more power leaving either an original amount or less of power then before?

The control electric power frequency is key to weather and GPS and ultrasound targeting for anti air system and most substation humming is help doing that plus agricultural rate of growth including control ether and sun light polarization

I worked at a nuclear plant for four years. It was very satisfying to walk past the output transformers feeding the switchyard and hear the deep 60 cycle hum; like this is where the rubber meets the road.

If the hum of a transformer changes significantly, it may be a sign that the transformer, or a supporting component, is about to fail soon. The change in sound should be investigated soon.

1. No capacitor.
2. Not in resonance.
3. Both coils are not at the same inductance.
4. The iron or steal core
5. The core is in plates.
I could go on lol.

Is the expansion and contraction the result of temperature change of the sheet? if so, does it follow that you can reduce the sound by using different materials?

Hi, i have a question. Is the thin laminated sheets of the core electrically isolated from each sheets? So, they have insulating coat in between each sheets?

Something I have wanted to look up for years! Thank you. Additional question, why is it 50 or 60 hz? And is that why screens also often use 50/60hz?

Very educational and informative, I was oblivious as to how transformers work and often wondered if the hum meant the transformer was going bad.

Joke may be because they are happy, they can't sing like humans. As humans can sing (well some of use can, so the transformer hum instead!

I think there are transformers in my guitar set up (uses 9V pedals) and I get buzz. Is there a chance the guitar picks up the buzz?

When i heard the humming sound from a transformer for the first time. i was legitimately scared!
I thought it was gonna EXPLODE

Great video thanks, now another question, is the heat generated ever used or is it always wasted. Could save some kWs if it could.

Transformers hum because their electrons are having a jolly-good time, even though they can only hum one note. Cheers!

And the hum is at double the line frequency because the magnetic field strength increases and decreases twice per cycle.

Well is just sound like 50 or 60 hz. Alot ppl misunderstanding this cuz the hum, such current leak or short circuit cause

It would have been a nicer conclusion to show the perceived sound of sinudoids with different frequencies.

because expanding and collapsing magnetic fields cause vibration. that is why the universe also hums.

That is not totally correct why Transformers Hum, the real answer is Because they Don't Know the Words.
