Anger Manage: what lake did you get busted on?
We conduct all of our testing to the J2005 standards. California just adopted the J2005 noise regulations a couple of years ago. The development of the J2005 noise law is the reason we started making mufflers. The post that describes the method of testing for J2005 is correct. The Dana tips you have in your boat with a 496 HO will be right at 86db's with the test conducted properly.
Just for your information, a 496 HO is only 93-94 db's with no mufflers installed. Who ever conducted the test most likely had the noise meter set incorrectly. Not only does the machine need to be set on the slow setting, but it needs to be on the "A" scale. Most likely he had it set on the "C" scale. "C" scale is extremely sensetive and will raise the db's significantly.
Unfortuntaley, I have first hand experience with law enforcement on this issue, and not to generalize law enforcement officials, but the guys we delt with didn't have a clue of how to use the meter or how to administer the J2005 test.
This is all great information to help fight a ticket.
Downtown 42, He was stopped on Green Lake, the cop said the property owners bought the decibel meters for them, go figure! Steve
