Weird engine sound (humming)

Hi everyone, I have a weird sound coming from what looks like the engine bay. It is humming of some sort. It is most noticable from the interior with with windows up. Please see the video below. I filmed it at night and the camera cought the noice quite well so it is even more clearly noticable than in real life. Anyone had similar exoerience in the past? The engine is fine otherwise, steering fluid level is not low.

I think you are going to need to look & listen under the hood to narrow that down more, sorry. Could be any of the spinning parts with a worn or failing bearing causing it. Or one of the hydraulic pumps. Or...


We really need more information to help.

Came back here to report that it is fixed. That specific noise turned out to be the ac pump pulley bearing. The pulley was removed and the new bearing was pressed in, good fix.

The problem was that it was not making a lot of noise in the engine bay when the mechanic was listening with the stroboscope. I think the best way in this situation is to put the AC on so that the compressor starts working, if the noise goes away or changes significantly, it is the AC bearing. Before I got there I replaced the tensioner pulley since it was also squeeking when cold and the idler pulley which had a little play.
