Any decent mic will do...
But you need two, or even four mics.
Suppose you use a cheap audio interface and two mics. Set one -20 dB to the other. That avoids any auto gain problems. If one distorts, use the other channel. And if the lower channel is too faint to understand, go for the higher gain channel.
NOTE: most cheap integrated USB mics won't do as they usually don't permit to set gain per channel. And they're usually not stereo, either. Same problem as most webcams.
I think one of the game console makers has a webcam with a mic array that could be useful. The Sony PS3 Eye. See:
https://en.wikipedia.org/wiki/PlayStati ... Microphone
But I don't know if you can change levels for the four microphones. Here's some info how to use it with Windows:

The Eye driver costs 3$, an Eye is around 10$, used on ebay.

Like I said I'm a bit of a dummie in this. Why do I need 2 or even 4 mics?
Could you suggest one without camera that I can integrate and use with my bit of knowledge? THX

Something like this possible:

I searched for 'microphone multi-directional background noise suppression' in google
but if possible I need integratable mic

This:
Built-in echo cancellation, noise reduction and full duplex communication
tells me this mic has been developed for use with Skype and other VOIP applications. It doesn't seem useable for your purpose...
Also, it's not overpriced if it's a good mic. It looks good, but I've never used one

Hi Cryano,
I searched for the keywords there are mentioned on the wiki link you have mentioned?

There are lots of mic array's but most will be out of your price range.
You could use just two very simple small mics. But it all depends on your audio interface. If that has a way to set gain for each channel, you're set.
For the audio.
Any one of these could do:

You need to check if these work with your OS, of course!
You'd still need to sync audio to video. And you haven't told me what you are using to edit video. Windows Movie Maker? Sony Vegas?

These interfaces all plug into a computer. I don't remember a computer being part of the rolling stock. Wasn't this supposed to be a better quality video camcorder or separate sound recorder? The original problem was high noise level as compared to the voices. How do two or four microphones help with that?
How were you going to record four microphones?

Cryano, audio and video is set sync by 'Rightbooth' :
http://www.rightbooth.com
This is a videobooth app that works nice and is affordable for what I'm using it
The set of 2 mics are looking nice but what after I bought it? What should it do then? I can mount it and connect it but what are the settings I have to make?thx
@kozikowski: you ask Cryano probably? I do not understand all of it so ... hope to find the solution over here, thx

Sorry I forgot, indeed it is used with a on board mini-itx soundcard so normally only use with 3.5mm or USB.
