The power transformer that is in my rented loft is very noisy. Is there a simple way of making it quiet?

Create an enclosure around it. There are plenty of acoustically dampening cloths. Use fireproof materials only. \nAlso make sure that the enclosure is vented.\n\nAs a precaution, leave an air gap of around three or four inches around all surfaces of the transformer's outside metal box. Lastly dont let the air inside ever get hot.

you need an x-14 reynolds conductor. If you can't find one, cover your head with aluminum foil and put headphones on, listen to John philips Sousa march music..this will keep the voices at bay

Reduce voltage spikes.\nMeasured in watt-second or joules.

Don't touch anything metal that is connected to the outside - i.e. plumbing, wiring.  \n\nMake sure you unplug your computer and tv sets (and anything else electronic) because a direct hit close by will fry the circuits in these things - or at least get some good surge protectors if you forget to unplug or aren't around.

insultate it with soundproof foam

It depends on the kind of heater it is. The most common way would be to reduce the speed of the fan, if possible. If it doesn't have a fan and the noise is from water or steam going through the pipes, then, a) there could be air in the system that's not supposed to be there, or b)the water or steam could be going through a small pipe or partly closed valve so fast that it makes a lot of noise.

Replace the jacks.  These things are not all that expensive.\n\nThe real question is why are the jacks there in the first place.

Buy better fans. Good brands are Papst and Panaflo.  Also the bigger the fan i.e. 120mm and the lower rpm they spin at , the quieter they are.  Stay away from small fans like 60mm

In addition to unwanted electrical effects, transformers may also exhibit undesirable physical effects, the most notable being the production of heat and noise. Noise is primarily a nuisance effect, but heat is a potentially serious problem because winding insulation will be damaged if allowed to overheat. Heating may be minimized by good design, ensuring that the core does not approach saturation levels, that eddy currents are minimized, and that the windings are not overloaded or operated too close to maximum ampacity. \n\nLarge power transformers have their core and windings submerged in an oil bath to transfer heat and muffle noise, and also to displace moisture which would otherwise compromise the integrity of the winding insulation. Heat-dissipating "radiator" tubes on the outside of the transformer case provide a convective oil flow path to transfer heat from the transformer's core to ambient air: \n\nFollow the link for more information.\nHope this helps you!

Go to your local electrician's shop

A air purifier is a start.  If its real bad, consider getting rid of carpets, rugs and pets.  Good luck.

You do not need to loose this fan, you need to find out why it is suddenly noisy.

set up a better ground of some sort or make sure your speakers are plugged in all the way

Transformer cores are made of several laminations of magnetic steel.These laminations are stacked together and bound tightly on a frame.Transformers work on the principle of electromagnetic induction.The magnetic flux passing through the transformer core acts on the laminations and cause them to vibrate.This results in a humming sound.\nUnusually high humming sound could be due to looseness of the binding of these laminations.

Just plug the meter and shut up......

open the volume control panel and mute your pc speaker, that will fix the problem

If this is your hard drive, you should TURN OFF the power.   That sound could be from the hard drive, and you have little time left.  Save your data and make backups, then get a new drive.   \n\nGood luck
