I think noise is a issue everywhere in the world now(unless you live in the dessert).
Actually, here in the deSert
we care quite a lot about it too - another area where the 902 is significantly ahead of the rest. When our 135 pops over where I live while I'm off-shift, you certainly know all about it. I used to have no problems sleeping-off my night shift when the 902 came to visit - never used to hear her. As I mentioned on another thread, though, the worst of the bunch has to be the BK117; both counties know when she's up and around down in D&C.
