I know that I'm weird but I find it easier to sleep with the noise of jets roaring overhead than without! That might well be because I was brought up in Suffolk, at the height of the cold war, when we had USAAF jets almost constantly roaring overhead.
I'm not alone though. The town where I live now is just down the road from what was RAF Wattisham. (It's now the Army's largest helicopter base in the country). I've heard many, many people here say how much they miss the roar of the Phantom jets constantly flying in and out .
