Yes Moscow is very noisy but who cares as long as trains go every minute

Soviet type metro is loud. But actually I never rode a silent metro. London, Paris and Amsterdam metro were loud too.
Athens metro seems very silent but slow too in this video

London's victoria line is much noisier to the passenger but from the outside, it might not be louder than NYC's trains.
It depends on the track, it is loud on old track, see here.

And on parts with new track it is quiet... See here.

One of the reasons for that discrepancy is the fact that they were recorded using different methods. One was recorded on a mobile phone (thus giving lower quality to the recording) and one was recorded using a proper camera.

Secondly, one was underground, and one was above ground, with the underground one of course being MUCH louder as underground stations have the wonderful "bouncing sound off the walls" effect, amplifying the noise of the tube due to the multiple constructive overlap of sound waves.

I wasn't making as much as a fuss as that, but bad track is noisier, that's the point I was trying to make without having to trawl through clips to make sure it's a "fair test" and since I use Oxford Circus EB on the Central line I knew that it was noisy, so wallah, I search for "oxford circus central line" and find a suitable clip!

So what? the problem is that is not only noise at the station, but on your way in train there is too much noise, too, sometimes you can't even talk to a person nearby.

I've been to metros of London, Paris, Brussels, Amsterdam, Moscow, Shanghai and some others. Moscow's is the noisiest. In Brussels and in Shanghai it is the quietest. Paris is ok. 3 ligne was awful with its MF-67 but anyway much better than in Moscow.

In Athenes it is not so quiet as I see from the movie. Brussels and Shanghai are much better.

Another clip from Moscow, this time inside the train, it doesn't seem to bad but the train isn't going that fast



And here's a clip I found of the horrible noise that you hear when going round curves, in London, I couldn't find one before...

I am not sure, but I had the impression the rubber tired metro lines of Paris were quite loud during acceleration.

How can you determine the noise level from a video as the volume depends on recording and processing of the video?

This site doesn't half attract it's fair share of hair splitters, doesn't it?

The videos are just there to give one an inclination of the noise that everyone is talking about, they're not meant to be some super-accurate scientific test.

SkyTrain Vancouver is disgusting when underneath the tunnel between Waterfront and Burrard... the screeching of the tracks and the wheels during the tight turns is horrible. And the speaker system inside skytrains aren't very loud, so it's possible that you can't hear the automated messages.

But I'm sure other places have louder metros than SkyTrain. I shouldn't be complaining. =)

Believe me, it's very hard to stand. In many places you may even yell when talking to a person nearby, but he or she won't hear you clearly. It's not the case for the whole system but generally if you want to talk in the car to someone, you've got to speak very loudly. When waiting for the train, the noise is also too strong, at some stations the same old story, the noisiest stations are so noisy that you can yell and you won't hear yourself (if you stand not very far from the coming/going train.

Do you have any proof? What is the noise from, the track or the trains themselves?

Not only not super-accurate but absolutely useless (except showing how the noise sounds).

And showing how the noise sounds isn't relevant? I think it very much is, an annoying buzzing sound is different from someone singing even if they are the same amount in decibels, am I right?

Shanghai's is probably one of the quitest around, based on my limited experience, anyway. I think it's because it's so new and the tracks do not have any really tight curves that cause a large amount of squealing.

No proves so far, but...
The noise has got many sources: train's engines (both acceleration and slowing down/braking), train's moving (because of bogie construction I think) - because there's much noise even if the train is running in "run-out" mode, with no acceleration from the engine. And one more reason in my opinion is in materials used for tunnels and stations. In my opinion, they don't absorb the sound well.
By the way, new trains in Moscow are comfortable for passengers (inside) but they are still too noisy while waiting for them. And, there's little noise inside only because it was provided with good noise insulation - doors construction, forced ventilation - so no need to open windows. But since you oper a ventlight, it becomes just the same as for old trains.
To prove it more, I can say, that in Brussels metro you may open a ventlight, but there would be still vry little noise.
