Default How do you test Engine DB's Properly

My local club has a noise level max of 100 DB. Thats not bad I know but I want to know how to properly test??? Do I stand 90 Deg and point the bird toward the wind (if any) and how many feet away is the correct way?
I beleive that the guys at the club are just walking up anywhere between 5 and 10 feet away around 90Deg at the side with the meter pointed directly at the engine and have the throttle full open while sitting on asphault??? Is this right? If I were on the grass and had wind to help, the DB's would measure much different.
I hope that I posted this in the right area as I have had no luck finding answers to this in existing threads nor on AMA's website. I found some stuff but it pertained to certain competitions.
Thanks guys
