Topic: Motorcycle exhaust noise considerations.

[scottly]

The intense sound caused by loud motorcycles easily triggers an involuntary stress response commonly known as "fight or flight." This results in the secretion of adrenaline, with ensuing spikes in cardio-respiratory rates, muscle tension, and elevated blood pressure.

You can download a PDF here from where this was quoted:  http://www.who.int/quantifying_ehimpacts/publications/e94888/en/

So you didn't tell the truth about WHO as the source of the quote? I suggest you read the WHO document again, as it states several times that the data is based on educated guesses, a lack of common test modality between the data sources (such as disregarding the noise from railroad traffic in some studies), the actual noise levels at night in the bedroom vs the living room in the daytime, etc.
The bottom line is annoyance noise is just that: annoying, whether it's a cat-fight or a Chevy truck with blown-out glass-packs if it's just outside my bedroom window at 3:00 AM. My hearing may not be damaged, but my blood pressure will certainly go up!

But, that is exactly what the WHO report identifies and quantifies scientifically as a diminished health effect. 
Did you even read the opening abstract?  Do your own opinions outweigh scientific investigations and conclusions?  Is your evaluation based on the assumption that everyone is healthy and in their most robust prime of their life?

The referenced report establishes and quantifies that increased noise levels cause loss of life.  And, that as the level increases so do the detrimental effects.  It is not a stretch to realize that if your pleasure craft emits noise levels above that of ordinary traffic, it contributes to an elevated and real detriment to persons nearby.

The following is taken from the WHO report abstract, for your convenience.

The chapters contain the summary of synthesized reviews of evidence on the relationship
between environmental noise and specific health effects, including cardiovascular
disease, cognitive impairment, sleep disturbance and tinnitus. A chapter on annoy-
ance is also included. For each outcome, the environmental burden of disease
methodology, based on exposure–response relationship, exposure distribution,
background prevalence of disease and disability weights of the outcome, is applied
to calculate the burden of disease in terms of disability-adjusted life-years (DALYs).
With conservative assumptions applied to the calculation methods, it is estimated
that DALYs lost from environmental noise are 61 000 years for ischaemic heart dis-
ease, 45 000 years for cognitive impairment of children, 903 000 years for sleep
disturbance, 22 000 years for tinnitus and 587 000 years for annoyance in the Eu-
ropean Union Member States and other western European countries. These results
indicate that at least one million healthy life years are lost every year from traffic-
related noise in the western part of Europe. Sleep disturbance and annoyance, most-
ly related to road traffic noise, comprise the main burden of environmental noise.

Can't let the truth/reality get in the way of a good argument .  I learnt that one from the ex-wife.

Have you considered your wife was right? 

You're doing it again TT - taking a scientist "identifying and concluding" something as unequivocal, unchallengable fact and then extrapolating it to make your point. The WHO statements are full of ambiguity. Well guess what, I'm a scientist and I have an opinion too that's just as valid as anyone else's opinion - remember the arsehole comment? And then, in the paragraph above which identifies the affect of traffic noise in Western Europe you cite this as a proof that motorcycle noise is the root of all evil. Well guess what TT, there are other vehicles on the roads and a lot of them a darn sight noisier than bikes so that bit of evidence is about as much use as a wet paper bag in being unequivocal proof of your point.

Stop pedalling all this subjective sanctimonious junk data as fact and accept that it's just your opinion. Sure it's shared by others and that's great but it doesn't make any of it right, it's just an opinion and other people are not wrong, they are JUST DIFFERENT.

Oh and while we're at it as the Olympics have just finished, let's take your "paper bag joke" example a bit further and ban sport too - one of the biggest contributors to regular adrenaline rushes out there and we'll all be healthier....NOT

a few years ago in my work as a rubbish truck driver we were emptying bins of dirt at a house,he wanted clean fill,we did about one a week a total of about four or five,the first time when i was emptying a bin there i noticed an old lady across the road watching me and drinking a cup of tea or something,i waved and said hi,she bellowed at me "why dont you make some more noise?"so i did,i made sure to drop the chains from a greater height and slam the bin over a few more times to make sure it was empty,i then sat there with the cummins idling as i checked in on the two way for my next job,slowly footing the brake and dumping air to make the compressor kick in.

The trade school I was going to last year was one block away from a harley dealer, and EVERY time one went past, my instructor had to stop instructing 'til it was far enough away. Waiting to cross a busy street, I watched two semis and a lot of noise approaching. There was a bike between them, transporting one hairless ape that was drowning out two semis which were hauling useful products for everyone. Defend away.
And Lloyd, you should know by now that logic and homo sapiens don't get along.

I for one am not defending it Tweetie-pie, I'm merely objecting to having subjective twaddle put up in lights as hard fact that I must obey. Each to his own as it will largely be within the law...

+1000.
Probably the same "scientist" that preach global warming.

The Olympics should be canceled not only for the adrenaline rush, but the noise of the crowd.
I'm sure when the crowd yells it is harming all their ears and they will never be able to hear again.
Poor bastards have to be protected from themselves you know.

Tweety-pie, what kind of pie is this?

A pie full of tweeters?

Sports crowds willingly enter an arena to participate in the event and know full well what they are getting themselves into.  It is private property (unless its a stupid state funded college stadium... don't get me started on that). 

The guy sitting outside at Starbucks adjacent to the public road while a pack of straight pipe Harley Davidson motobikes drive by isn't signed up for that.  The damage caused there is completely the fault of the bikers that choose to operate their bikes at an unsafe sound level on public roads...  That is the distinction here and that is when fault is given to a motorcyclist.

Probably the same "scientist" that preach global warming.

I see one of your biggest climate change deniers has jumped ship, the research he did was to disprove climate change and was funded by an Oil Conglomerate, ended up completely changing his mind, its only the fools that think there's nothing happening...

Climate-change denier changes his mind....

The verdict is in: Global warming is real and greenhouse-gas emissions from human activity are the main cause.

This, according to Richard A. Muller, professor of physics at the University of California, Berkeley, a MacArthur fellow and co-founder of the Berkeley Earth Surface Temperature project.

The United Nations Intergovernmental Panel on Climate Change and hundreds of other climatologists around the world came to such conclusions years ago.

However, the difference now is the source: Muller is a longstanding, colourful critic of prevailing climate science, and the Berkeley project was heavily funded by the Charles Koch Charitable Foundation, which, along with its libertarian petrochemical billionaire founder Charles G Koch, has a considerable history of backing groups that deny climate change.

In an opinion piece in Saturday's New York Times titled The Conversion of a Climate-Change Skeptic, Muller writes: "Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming.

"Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct.

"I'm now going a step further: Humans are almost entirely the cause."

The Berkeley project's research has shown, Muller says, "that the average temperature of the earth's land has risen by 2 degrees Fahrenheit (1.1 degrees Celsius) over the past 250 years, including an increase of 1 degrees Fahrenheit (0.55 Celsius) over the most recent 50 years.

"Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases."

He calls his current stance "a total turnaround."

Tonya Mullins, a spokeswoman for the Koch Foundation, said the support her foundation provided, along with others, has no bearing on results of the research.

"Our grants are designed to promote independent research; as such, recipients hold full control over their findings," Mullins said in an email.

"In this support, we strive to benefit society by promoting discovery and informing public policy."

Some leading climate scientists said Muller's comments show that the science is so strong that even those inclined to reject it cannot once they examine it carefully.

Eh? How'd you figure that one out? The guy sitting ADJACENT TO A PUBLIC ROAD, is not signed up to hearing traffic noise? He chose to sit there, is he so dumb he expected the road not to be used, the PUBLIC road that is. If he wants his coffee in silence he needs to go find a library to drink it in.

You see you just underline my point, it's about choices. The Harley riders choose for (some reason) to have loud pipes, probably because the sound is the only redeeming feature of their agricultural steeds    but equally the starbucks man is choosing to drink next to a public road that the public uses to drive itself down. If he doesn't like his choice because it didn't live up to his self made expectations, guess what!? He can choose to move somewhere else. Why should the fact that he made a 'bum choice' measured against his own personal and unique values and beliefs mean that the bikers are in the wrong?

So you're right - this is nothign to do with right and wrong it's all abut choice and opinion and as we all operate in our own unique contexts in this world, there is no conclusion that either "side" in this argument can force the other to reach. The map is not the territory...

I honestly find the landscaping equipment in my neighborhood to be far more annoying on a daily basis. Between the grass cutting rigs, leaf blowers, weed whackers and 2 stroke powered brooms I'm ready to lose my mind. My neighbor (who is an engineer and cannot take a crap without a blueprint and extensive operation analysis) has what has to be the loudest GD grass cutting contraption I have ever heard. It has the jockey set up and uses a large Kawasaki engine with hydraulic drive for the blades and transmission. Christ on a cracker....once that drive is engaged it is unbelievable even at 100 feet away.....sitting in the house! Combine that with the fact has has to go over the lawn in 8 different friggin directions to achieve optimum patterns and blade length. After listening to that thing for an hour every week I would gladly listen to an occasional loud bike.

when he was constipated badly he just worked it out with a pencil and paper?
