Weird noises on Shahikot Mountains map?

Every time I play the Shahikot Mountains map on MOH for 360 I hear annoying electronic-type noises as well as what sounds like someone sitting in a creaky chair. The sounds actually make me feel a little sick. It's weird though because it is only on that one map. Does anybody else hear it? Is it supposed to be part of the background noise? If so, what on earth is it supposed to be? Thanks.|||I've never really paid attention but it may be that dumb satellite dish that rotates on certain areas of the map...check it out to see if that is what it is.
