RE: Flying Field Airplane noise
"flyfisher431", I'm afraid y'all are done in. Most municipalities have that sort of ordinance already on the books, to be enforced at will. Someone has either been flying very loud planes or bad relations with a nearby neighbor made him decide he doesn't like the noise. If your field has been there a while, you might try to talk the powers-that-be into grandfathering your location. Good luck.
"housedad", you're dead wrong. The police can and WILL enforce it. They WILL come out with a dB meter and check. It's not subjective at all. If the meter reads over 5dB increase, you're fined. I've seen it happen.
If the surrounding area is already noisy, the club might be in luck. The one thing that also might save you is that sound levels are logrithmic. Twice the distance from the noise source may lower the dB 4 times. I suggest the club buy the same meter the police will use and do some testing "at or within the boundary of the property of the receiving land".
Again, good luck.
