New sound restrictions @ Glamis?
I heard a rumor that there is going to be a new restriction on the noise level from your bike @ Glamis this year. The rumor is that you can't be over 96db., and that they are testing your bike running @ 75%, 6 inches from the end of your silencer. Has anyone else heard of this, or at least know if there is any truth to it? If it is true hopefully it's just something they're going to use to controll the people who are out of control and causing trouble.

I'm not in california, but that sounds a little strict to test it only 6 inches from the end of a silencer. no one is listening to any pipe at that close of a range, so it would make more sense to test it a little further away.
There are 2 scales recognized by OSHA concerning sound metering, so what scale are they testing it on- the A scale or C scale? It a nutshell, the A scale is what most noise ordinances are based on. The C scale measures sound a little different and will register a higher db reading than the A scale.
hell, why dont they just stick a db meter inside the combustion chamber and take that reading. that will be nice and loud for them.
at least 96db is more generous than the US forestry service, which set its limit at 93db.

follow up on the distance
<snip>
The microphone shall be located behind, 0.5 m ± 0.01 m (20 in ± 1/2 in) from, and within 0.01 m (1/2 in) of the
same height as the exhaust outlet and at a 45 degrees ± 10 degrees angle to the normal line of travel of the
motorcycle. If there is more than one exhaust outlet per side, the microphone shall be located with reference
to the rearmost outlet.
The longitudinal axis of the microphone shall be in a plane parallel to the ground plane. The axis of the
microphone shall be oriented as specified for free field response by the manufacturer (see Figure 1).(20 in ± 1/2 in)

i have a crappy internet connection and had posted the 6 inch protest before reading your link to the official site stating their proceedure. thanks.
anyway, that is still too close. b/c I know when they rate speakers and stuff -- its rated/measured at aleast 1 meter from the sound source (the speaker). 3 feet 3 inches. Now, of course, you could be in a concert with over 100db easily standing many feet from the speakers, but the point is this is how speakers are rated from the manufacturer.
in the same realation, the pipe an an atv is the sound source so they should follow the rest of the sound world on this as well, IMO.
why is ATV sound metering at a different standard?

noise limit??? for what? are we disturbing the sand? pure ignorance. the rangers should be cracking down on the morons that go out and hurt themselves and make it completely dangerous for everyone else.
right on, man. but too bad that most of the time people think all atvers are morons. no, they cant crack down on the bad apples- they have to screw everybody over. it sucks.
