Would be great if the RS3 or M3 reach out to Alec Choy. It's time we stand up against these moronic police officers. Attachment 31099

He seems like a guy who can bankroll something, but high chance it gets shut down before anything happens because "We are the law and therefore immune to anything."

You'd think Cain would slow his vendetta. Boy was I wrong.

I saw someone mention freedom of information request in regard to VIs. Has anyone made a request before?

Freedom of Information and Protection of Privacy Act

If anything, if everyone that got a VI just send one of these to annoy the police...

Hmm... at least the noise meter isn't shoved right up the exhaust pipe, but that still looks like it is pretty darn close...

That’s a busy location, just imagine the noise coming from all that traffic

this is a good time for an ELI5

How do sound meters work? how does sound work? I'm pretty mechanically minded, but I have no idea about acoustics. 128kb and 256kb Mp3's sounded the same to me in winAMP

If the meter is sitting on the ground like in the pic above, adn the car is off - can it give you the reading of ambient sound? like say 30db of traffic and wind and other shit?

The MVA states that 83db is the limit for exhaust (i think). I've heard it explained here that it's supposed to be in a quiet controlled environment (like a testing station).

Do the VPD's sound meters take a "tare" sound level? Like I would zero out a scale based on the container weight before i measure its contents? is the reading calculated by subtracting the ambient sound level from the meter's result? do sound levels stack up like that?

I'm sure google can tell me this, but I'll bet there's an audio engineer on RS who can explain it better.

we all know you can't dispute VI's, and we've discussed that there is total ambiguity about how the meter is used, but I'd certainly be disputing the "excessive sound" tickets (and 3 points)

We have a meter out at the autox pad, I've never played with it. I think next time I might.

Kind of a theadjack , but I'm interested and would like to be educated if I run into one of the above situations so I can document it correctly.

I'm pretty sure the decibel meter test won't hold up in court, I'm not sure why they do this. The officer that did mine had the meter running off the charts (94db). There's no way my car is that loud when they tested it, especially roadside at a super busy intersection.

Someone on that same thread on Facebook posted a graph showing that every time you double the distance of the meter from the source of the sound it drops another 6dB... so if it's like 12" away like in that photo and measuring 90dB if he moved it to 2 feet away it would theoretically drop to 84dB... and likewise the exhaust would not be illegal to anyone in the vicinity who would be like 20+ feet from the car at any given time.

In short, the testing procedure is everything. A totally legal car can easily be made illegal depending where the microphone is placed.

Can you refuse the sound check? Do they have the power force you to rev your car?:rukidding:

You can refuse anything.

They may beat your ass to the Traning Day soundtrack, but you can refuse anything.

A bit of a dick move, but could one ever request or question when the sound device/microphone was last calibrated? Putting on the wrong filter on the mic could make or break your test sometimes. Like 68style said, the testing procedure can easily be the line between a simple pass or fail. If the mic is sitting on a crappy tripod on the floor and trucks are running on the same track, the mic could pick up any vibrations and ambient noise.

Also curious about this. If they're measuring the sound based off of excessive revving not reflective of how the individual was driving, they may as well give a speeding ticket for being parked as well just because a car CAN go over the speed limit.

Yea, they might give you a distracted driving ticket at this point too cuz you have a phone on you:rukidding:

I played with the sound meter at autox a few times.
Things like clear skies or cloudy overcast will have affects on the db.

My straight piped CRX at WOT is loud as heck inside the car but falls under 92 db on the pad but I wouldn't try driving that car on the street. Insta box 1 and sent to the crushers.

but in this case, with the mic right behind the exhaust, and that close, a stock exhaust might fail too. :heckno:

can these fkc give VI to those running hid in non hids housing. plz

Just saw a post from the Porsche club of a stock 911 getting a noise violation ticket. Hopefully it gets the attention of some well educated and hopefully connected members. It may go a little further then some fast and furious teenagers. Lol.

Sorry if it's been posted but has anyone disputed a noise violation ticket? What was the outcome?

Any word of what happened in court between Duke and Cain?

last I heard it was starting April 4th 2019

Who cares LMFAO

So here is a recent development on the VI issue:

There's people that do

Does traffic even matter?

I don't think traffic "adds" to noise. It's not like if your car is 60db and a 60db car drives buy it's going to read 120db.

A normal car may be quiet but the noise coming from the tires against the road will make more noise than the engine. Plus since this particular incident is on a bridge, there's also the added noise of the tires going over those bridge sections that I'm sure all of us hear every few meters when driving over a bridge. And what if a bus or truck drove past as the test was conducted?

But if a 90dbA dump truck drives by that will change what it reads. Or if it's next to a building the building will amplify the sound due to reflection.
