Noise restrictions bylaw coming for Oakville

What the H.E. double toothpicks is wrong with you guys? There are must as many noisy Civic's out there as there are motorcycles. Is it fair they target only motorcycles?
How are you gonna feel when your stock mufflers are being checked on the roadside as ten noisy civic's go by and are ignored by said cops?

Check the constitution. No mention of vehicle type. Drunk drivers lose their licences. Is that discrimination against drunks?

It is perfectly legal to discriminate against people that break reasonable laws.

IMO the loud pipe, fart can exhaust people are simply self centred. I doubt any of them would welcome the noise if they are trying to sleep or concentrate but it's OK for them to disturb others.

People tend to target what they see as a problem. It would seem that, in Oakville, them don't consider Civics with fart pipes to be a problem.
 
This effects more than just cruisers with straight pipes. I think my dealer told me that the stock exhaust on my gsxr was around 96db as it was regulated by law. This means all the sport bike riders with aftermarket exhausts have a target on their back as the police now have just cause to pull them over.

Luckily I'm probably the 1% of sportbike owners that rocks a oem exhaust.
 
There is no way your OEM exhaust is close to the limit, you should be fine. The 96 dB is not using the same test procedure. If there is an OEM exhaust that is anywhere close to the SAE J2825 limits, I have yet to see it. Keep in mind that due to the logarithmic nature of the dB scale, 3 or 4 decibels is a very big margin.
 
My stock mufflers say right on them, " max 80 decibels"

"When they were new" lol.

Just did the "official" test with my buddies iPhone and the DB meter app. His 1992 ninja stock exhaust failed, 94.6db idle! We'll see how it does on test day :D

Mine is definately louder than 80db. Everyone thinks I have an aftermarket exhaust when I ride. Most people change their muffler as their first mod on their bike, so they really don't know what it sounds like after its been worn in. But after a while and the packing starts to go, those OEM exhaust can sound purdy.

I tested my bike beside someone with the same bike and stock exhaust. His sounded like a puddy cat compared to mine. I had about 30k more on my bike. (And occasionally water may get into the pipe while washing the bike and damage some of the baffle packing) ;)

Are you sure the meter was on the correct scale and "slow" response? A measurement that high at idle for a 4 cylinder bike (this is an assumption - you didn't state which model) is unusual. Hindle straight-thru glass-packed muffler on my race bike with no additional noise-reducing baffle was in the high 80's.

Most stock mufflers are not reliant on packing, they use chambers and perforated pipes and perforated baffles. Granted, corrosion over the years can still take its toll ...

The 80 dBA standard test (which came in in 1983, by the way) passes any silencer which during a drive-by acceleration test, with the bike at 7.5 metres from the microphone and passing it at that same distance, does not emit noise of more than 82 dBA.

The 92 dBA maximum at idle and 96 dBA at 2000 rpm for bikes with 1,2, or more than 4 cylinders or 3, and 4 cylinder bikes at 5000 rpm test levels are supposed to equate with the moving drive-by test at 82 dBA. And the stationary test places the microphone at 0.5 metres distance from the exhaust and at a 45 degree angle to the silencer tip.

One of the concerns with measuring sound, even with expensive, purpose made, meters is the need for proper and frequent calibration to a sound source of known level. Other factors, ambient wind speed, reflection from nearby walls, curbs, bystanders, reflection of sound from the roadway if the bike is left on a prop stand and not held upright, problems with holding a reasonable idle, 2000 rpm or 5000 rpm with the engine not under load, or even getting an accurate rpm reading on some bikes, can result in problems.

Using the Iphone introduces the question of which (or what) microphone was in use and I believe that the headset microphone has the better response curve for DB level measurement use in which case the earphones must be covered up so as not to affect the accuracy of the measurement.

For example, the SoundMeter App for IPhone by Faberacoustical is stated to "not meet ANSI or IEC standards for sound level meters" and may be 6 db or more off the actual sound pressure level and requires calibration against an external standard for accurate measurement.

How exactly is this going to be enforced anyway?

Even if every officer was equipped with a dB meter, which isn't happening, tests would need to be standardized. As AFJ mentioned, there's a lot of ambient noise and other factors to consider. How could you possibly get a ticket for this (or at least, how would it ever stand in court) without them basically taking your bike into a soundproof room to run a test?

A bunch of the cop motorcycle have the testing equipment right on board. I was told that if a cop "thinks" you bike is loud, they write you a ticket to report to a test center (like driveclean).

As far as I know that is probably the way it will work in the state of New Hampshire - but nowhere in Canada. The province of Ontario (Ministry of Transportation) has written to the Town of Oakville stating that the province is not interested in changing the Highway Traffic Act to bring in a numerical standard for noise levels related to a stationary test on motorcycles. Oakville's by-law is just that - a local town-only by-law.

As long as a little caution is used (ie. don't conduct the measurement when a vehicle is driving past) there is little problem with ambient. Ambient sound 10 dB below the measured level will have less than 0.5 dB effect on the measured level. We had no problem measuring Brian's bikes in his subdivision. If they tried to conduct the test at the side of a busy road, you may have an argument, but it is easy for the cop to ask you to pull onto a quieter street.

One of the court cases on the Edmonton J2825 anti-motorcycle noise by-law was won by the defence because the police had the motorcycle pulled into a narrow alleyway with high walls on either side in order to run the test. It seems to have been either an obvious attempt by the police officials involved to increase the noise level reading by reflection off the alley walls or ignorance of the actual test method as written down by the SAE. Either way it was "case dismissed" and this year the indication is that the Edmonton police are backing away from large scale "pullover sessions" of all motorcyclists.

Jamie,

when you guys go do this... keep in mind, they aren't enforcing the by-law, but it doesn't mean they won't be enforcing OTHER laws.

Thanks for the heads up. I think my bike is pretty good, except the questionable headlight colour, illegal front signals, illegal rear signals, no mud flap, questionable license plate light... I think that's it :)
