The metal container is a Faradayan Cage, which not only protects you from lightning, as most of you know, but also prevent most electromagnetic waves to penetrate the inside. Sometimes even the ultra high frequence of mobile phones is affected, depending on the type of metal and the thickness, so sometimes you can´t use those phones there.
So, when the door is shut, you are pretty much "secure" from any electromagnetic noise, which is generated by every electrical machine. On a construction site, there should be more than enough of these "noise generators".
Once you go outside of the container, there should be a similar static noise on your tape recorder. It may be possible that the open door and the metal cage function as a kind of amplification for the noise, too, so it may be better outside of the container.

Thnx

Anyway I doubt that being outside will be better... It's hot (I think the news said 42c), it's noisy, and they don't have a computer there... They are, however, able to use cell phones. Since it's a large area and it already has three parking floors underground they comunicate with each other through cell phones all the time.
