elect more democrats

[BCT748]

The bill, which will be debated by city council Dec. 18, would require motorcycles to bear tags bearing Environmental Protection Agency approval certifying the bike would not exceed the city’s 80 dB noise limit.

The bill is based on legislation passed in Denver, Colo. in 2007 requiring motorcycles made after 1982 to carry EPA compliance tags for the city’s 82 dB noise limit.

How can they write the law if they don't even know how many decibels are too many?

elect more democrats

Noooooo! It's all their fault!

Gotta love living in a FREEEEEE country.....................

[wookie]

new york used to be a shit hole, then they started enforcing quality of life violations (you can now get arrested for drinking a beer in a paper bag and peeing in the street). That helped certainly, but now they have taken things too far. Just because a little is good doesn't mean a lot is better.

80 decibels????

WTF!!!!

Stock 1098 Ducatis run at 98 decibels.

My wife yells at 106 decibels.

80 is just way too low.

[breakdirt916]

aren't people just going to swap out their stock pipes after getting the EPA sticker?

[BCT748]

You mean like how most people around here do that to get inspection stickers? (Or at least plan to do that next year)

They might get away with that if they grind off the stamp that says "For race use only" that is on most aftermarket pipes, or the cops are too stupid to look for it.

98 decibels?!?!?!?!?! Jesus Christ. If that's true than my 748 must be close to double that.

Bring it down we have a decibel meter at the store.

Bikes are away for the winter It's not so much because of the cold than it is the salt/sand and now downed trees in the road. I might have to borrow/rent/buy/lease a db meter from you just to see how loud it really is

Yea after hearing your bike at Ted's place, i am pretty sure you would get a ticket from a mile out

You were there I was half asleep that night and was busy staring at all the stuff on the walls anyway. Next time let me know who you are, I'd like to shake your hand just because you tea bagged Noels bike and made him lick it right after

[ultraTwist]

Not sure but I thought the 80db limit was already the law, what do they need another one for?

Looks like the existing law in MA is pretty restrictive, and anyone w/out an OEM pipe can be ticketed. However, I'm not sure if this applies to motorcycles, since there are more rules about motorcycles which I'll also post.

http://www.mass.gov/legis/laws/mgl/90-16.htm

Chapter 90: Section 16. Offensive or illegal operation of motor vehicles

Section 16. No person shall operate a motor vehicle, nor shall any owner of such vehicle permit it to be operated, in or over any way, public or private, whether laid out under authority of law or otherwise, which motor vehicles are prohibited from using, provided notice of such prohibition is conspicuously posted at the entrance to such way. No person shall operate a motor vehicle, nor shall any owner of such vehicle permit it to be operated upon any way, except fire department and fire patrol apparatus, unless such motor vehicle is equipped with a muffler to prevent excessive or unnecessary noise, which muffler is in good working order and in constant operation, and complies with such minimum standards for construction and performance as the registrar may prescribe. No person shall use a muffler cut-out or by-pass. No person shall operate a motor vehicle on any way which motor vehicle is equipped (1) with a muffler from which the baffle plates, screens or other original internal parts have been removed and not replaced; or (2) with an exhaust system which has been modified in a manner which will amplify or increase the noise emitted by the exhaust. No person operating a motor vehicle shall sound a bell, horn or other device, nor in any manner operate such motor vehicle so as to make a harsh, objectionable or unreasonable noise, nor permit to escape from such vehicle smoke or pollutants in such amounts or at such levels as may violate motor vehicle air pollution control regulations adopted under the provisions of chapter one hundred and eleven. No siren shall be mounted upon any motor vehicle except fire apparatus, ambulances, vehicles used in official line of duty by any member of the police or fire fighting forces of the commonwealth or any agency or political subdivision thereof, and vehicles owned by call fire fighters or by persons with police powers and operated in official line of duty, unless authorized by the registrar. No person shall use on or in connection with any motor vehicle a spot light, so called, the rays from which shine more than two feet above the road at a distance of thirty feet from the vehicle, except that such a spot light may be used for the purpose of reading signs, and as an auxiliary light in cases of necessity when the other lights required by law fail to operate.

No person, except a duly authorized person driving an emergency fire vehicle, shall operate a motor vehicle equipped with metal studded tires upon a public way between May the first and November the first; provided, however, the registrar may authorize the use of such tires before November the first, if weather conditions require the use thereof. Whoever violates the provisions of this paragraph shall be punished by a fine of not more than fifty dollars.

First, we've got the specifications here
http://www.mass.gov/legis/laws/mgl/90-7s.htm

Chapter 90: Section 7S. Motorcycle sound emissions; definitions

Section 7S. The following words used in this section twenty-four A to twenty-four C, inclusive, unless the context otherwise requires shall have the following meanings:—

“A-weighted sound level”, the sound level in decibels as measured on a sound level meter using the A-weighting network. The level is designated dB(A).

“Decibel (dB)”, a unit for measuring the volume of a sound, equal to twenty times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure; which is 20 micropascals or 20 micronewtons per square meter.

“Motorcycle”, any motor vehicle having a seat or saddle for the use of the rider and designed to travel on not more than three wheels in contact with the ground, including any bicycle with a motor or driving wheel attached, except a tractor or a motor vehicle designed for carrying golf clubs and not more than four persons, an industrial three-wheel truck, or a motor vehicle on which the operator and passengers ride within an enclosed cab.

“Person”, any individual, association, partnership, or corporation, and includes any officer, employee, department, agency or instrumentality of the commonwealth or any political subdivision of the commonwealth.

“Registrar”, the registrar of motor vehicles.

“Sound level”, the weighted sound pressure level obtained by the use of a sound level meter and frequency weighting network, such as A, B or C as specified in American National Standards Institute specifications for sound level meters (ANSI S1.4-1971). If the frequency weighting employed is not indicated, the A-weighting shall apply.

[Danno]

http://www.mass.gov/legis/laws/mgl/90-7t.htm

Chapter 90: Section 7T. Motorcycle sound levels; testing regulations

Section 7T. The registrar shall adopt regulations establishing test procedures and instrumentation to be utilized for measuring sound levels of in-use vehicles. Such regulation shall include site criteria and moving and stationary vehicle measurement procedures and shall take into consideration accepted scientific and professional methods for the measurement of vehicular sound levels. The measurement procedures shall include adjustment factors to be applied to the noise limit for measurement distances of other than fifty feet from the center of the lane of travel and shall allow the extent feasible sound level measurement and enforcement action to be accomplished in reasonably confined areas such as residential areas of urban cities and off highway locations. Test procedures established by the registrar shall be in substantial conformance with applicable standards and practices established or recommended by the United States Environmental Protection Agency.

[Danno]

And after all the definitions, here's the actual law

http://www.mass.gov/legis/laws/mgl/90-7u.htm

Chapter 90: Section 7U. Motorcycles; maximum sound levels

Section 7U. No person shall operate a motorcycle intended for use on the highways of the commonwealth and registered under the provisions of section two of chapter ninety at any time or under any condition of grade, load, acceleration or deceleration in such a manner as to exceed eighty-two decibels when operated within a speed zone of forty-five miles per hour or less, or in such a manner as to exceed eighty-six decibels when operated within a speed zone of over forty-five miles per hour measured at fifty feet using the prescribed highway vehicle sound level measurement procedure.

No person shall operate a motorcycle intended for use off the highways of the commonwealth and registered under the provisions of section twenty-two of chapter ninety B at any time that exceeds one hundred and three decibels measured at twenty inches, or one-half meter, using the prescribed stationary vehicle sound level measurement procedure. For enforcement purposes a tolerance of plus two decibels shall be applied to all measured sound levels of in-use vehicles to provide for variances in equipment calibration, measurement site characteristics and measurement techniques.

[Danno]

Now that I've (hopefully) found the relevant laws, I can see why the confusion over two levels. One is 45 or below, and the 86 db number is 45 or faster, as on the highway.

Let's take those numbers and apply the open field rule, where halving the distance would lose 6db. We go from 86 db at 50 feet to 92 at 25, 98 at 12 (rounding down), 104 at 6 and 110 at 3 feet, or 106 if we're under 45 (idling? not clear what this means)

I haven't run any tests w/my db meter, but 110 is pretty damn loud. I'd guess that your typical straight pipe cruiser is that loud, but most aftermarket cans that have *any* muffler element will be lower than this number.

Here's a useful chart for comparison.
http://www.gcaudio.com/resources/howtos/loudness.html

Note that a power saw at 3' is 110db - they don't say if it's a chainsaw, portable circular but they also think a motorcycle at 3' is 110db.

Pay particular attention to the OSHA Daily Permissible Noise Level Exposure - for 110db it's a half hour a day.

[banzairx7]

Interesting in the "Perceptions of Increases in Decibel Level" section that to the ear 10db sounds like a doubling. Even though every 3db is a real doubling. Weak ass human ears...

[Danno]

It's well known by musicians and audio enthusiasts, (I'm both) but not at all intuitive.

You double the power to gain 3db and ten times the power to gain 10db.

Though some people can detect a 1db change, 3db is generally the lowest perceptible change for most people.

[DuncanMoto]

So now I see why Two Bros tunes their cans to run at 103 decibels. Now I'm not quite sure how Ducati can have the stock 1098 cans run at 98 decibels, but I do understand the flapper valve thingy now.
