Pitt Meadows, BC Canada | Here is what is happening in my local community - and extending through all the towns and cities of B.C. RCMP Press release:
Police Tackling Noisy Vehicles
The onset of summer is not always good news for some Lower Mainland residents, who dread the increase in noisy motorcycles and other vehicles on their neighborhood roads.
The North Vancouver RCMP and Port Mann freeway patrol are inviting motorcycle riders and other vehicle owners to attend the parking lot of the Main street off ramp at the Ironworkers Memorial bridge, on June 5th and 6th from 8:30 a.m. to 5:30 p.m. for free decibel testing of their exhaust systems. This type of testing has never been offered by the police before and will be a unique opportunity for riders and drivers to become more aware of their noise levels. Trained Police officers will determine if the noise levels from the exhaust pipes are illegally loud.
On these days only, drivers will be offered an amnesty (no charges) by the police in North Vancouver. If their vehicle is found to be above the legal decibel limit, the Police will explain how to make the necessary improvements. Only street legal and street safe motorcycles and vehicles will be tested.
- If a motorcycle, car or truck is making more noise than a factory model, it is too loud.
- If after-market pipes have been installed they likely do not have baffles and are not legal.
- Most after market products are not approved mufflers.
Extensive enforcement for noisy vehicles will take place during June to October. Drivers charged under Section 7A.01 of the Motor Vehicle Act - Regulations will pay a fine of $109 and receive three points. If the noise is too excessive, vehicles could be towed and license plates seized, requiring the owner to have the vehicle inspected and then re-licensed.
“I have pulled over many motorcycles over the years and have heard all kinds of explanations,” says Constable Peter Kennedy with the North Vancouver RCMP. “None of them were valid, especially when someone says that the noise is for safety reasons and could save their life. Noisy motorcycles do not save lives, they simply irritate other people enjoying a peaceful day. The general public does not enjoy the noise and have made many requests with the local police agencies and the Mayor’s office for serious enforcement.”
Motor Vehicle Act Regulations
“A motor vehicle shall be equipped with an exhaust system which ensures that the exhaust gases from the engine are cooled and expelled without excessive noise.”
“The opinion of an inspector as to whether the engine and exhaust noise is greater than that made by other vehicles in good condition of comparable size, horsepower, pistondisplacement or compression ratio shall determine whether exhaust gases are expelled with excessive noise.” |

...post time out, I wasn't targeting trailbarge, but the guy trailbarge made the observation about. I didn't want anyone, especially trailbarge to misunderstand my comments.
I had to think for a long time to remember what a RUB was. Anyway, I am a MIUB, which is why I don't have any upgrades on my bike to brag about in my signature.
I'm a little sorry that I started a bit of a holy war here. I just wanted to share the imagery of the amphetamine-crazed monkey = and bring a smile to a few people. Didn't know I was stepping on the word ex cathedra about asswip.... er - "genuine non-RUB bikers" and their prima facia assumption of a right to ruin everyone's day.
oops.... that doesn't tone it down much, does it ? heh, heh |

North Orange County CA | Thanks for the correction TB, it's just one more example of why having a working knowledge of "times and gazintas" is so important. I blame my shortcomings on the school system, 'cause it surely cant be MY fault.
BTW thats sure a lot of Latin your throwin' around.

Decibels are measured on a logarithmic scale, so a 90 DB measurement means that the noise level is perceived by the human ear to be approximately DOUBLE that a stock EPA compliant (80 DB ) exhaust, a 100 DB system would be 100 times louder than that same street legal bike. That's a pretty serious difference.
Close. Each 10 decibels is 10X... not 2X. You have the idea, because you correctly identified 100dB as being 100X louder than 80dB.
With respect to 80dB, 90 dB is 10X louder, 100dB is 100X louder, and 70dB is 1/10 as loud.
0dB is the baseline, which is an arbitrary line considered to be the limit of human perception... about .002 microbar delta P, if i remember correctly
I was tought that the signal doubles strength every 3db. Maybe that's just RF gain but I think that it holds true for every spectrum. (i.e. 10 db gain would equal just over three times the noise baseline). ? Dunno. Either way, I'm with you. There are few things that piss me off more than a POS Sportster with pipes so lound I can't hear myself think. Most of these guys have chip on their shoulder. I have tried to get my exhaust note "just right" on the Vision but I will NOT sacrifice 1 single ft.lb or torque so I have pretty much went to St1.Lvl2 pipes and left it at that. I pulled the baffles for awhile to see if I could go back to a louder bike and didn't enjoy it. I DO play the radio loud though!!! Everywhere I ride I blare the radio so as to drown out the noise of the traffic. Once traffic is gone, radio pretty much goes off. If I can hear nature (birds and such), then I could care less about music. Not that I'm a tree-hugger either! Maybe I'm just getting old or something. After owning a full fairing bike I will probably not be happy with anything less. I could use an extra decible or 2 of exhaust for the open highway (love the way the motor sounds when it loads up) but I despise open pipes lately.

We are on the same page. 10dB difference is 10X strength.... or....
base x 3dB difference is 2X, x 6dB is 4X, x 9dB is 8X, x 12dB is 16X... so 10X strength would fall between 9dB and 12dB.
I DO play the radio loud though!!!
Me, too. More than once, I've been on the superslab and sensed a car hovering next to me. I look over to see someone filming me as I chair danced to the music. Embarrassing... especially since there is absolutely NO chance that they are filming me because of my good looks. (I'm as ugly as a bucket full of armpits.)
My wife says she hears my radio coming into the neighborhood before she hears my bike. I tell her its only when a really good song comes on.

I actually AM a bit of a tree hugger. Before I broke my leg, I used to spend at least a week a year in the back country somewhere. I don't put myself to sleep reading "How to S**t in the Woods" (yeas, that's a real book) or anything, but I have an appreciation for our wilderness preserves.
When I want to hear a good tone from my bike, I drive under a bridge. We have one here in Goldsboro that never fails to bring a smile to my ugly puss... if only for a few seconds. I could also always go find a tunnel.... WOW! |

New Bohemia, VA | ...it's getting too cold around here for the "loud pipers" and I'm not waving as much. Does quiet pipes + fringed jacket = gay? or does that equate to pansy? just curious... |

Bullhead City, AZ | Wifeunit had a guy the other day where she could hear the bike but not see him. Lucky for him she had the windows down and knew the bike was close. When she found him he was in the blindspot passenger side of the Forester trying to pass as she was turning into his lane. She just got her bike license and they really drilled the part of being invisable in class. No harm no foul everybody went home happy. |

Gross HAWG observation (warning: GROSS)
