That's funny - I had no idea it was actually banned in the first place. I live near a number of large military bases and hear the fighter jets break the sound barrier on a somewhat regular basis.
I believe the supersonic ban is/was on civilian aircraft.
Are you sure you're actually hearing sonic booms? The low-bypass turbofan engines used on most current tactical aircraft are quite loud even in subsonic flight. F-35 and F/A-18 fighters overfly my house occasionally and while I don't mind the noise they're definitely much louder than airliners. They generally only go supersonic over designated training ranges away from heavily populated areas.
