Noisy Idling Vehicles

[jyl]

Different types of passenger vehicles seem to have to meet completely different noise requirements. When an typical car is idling on the curb beside you , it is hardly noticeable. When a diesel pickup truck is idling, it is so loud you can't even have a conversation without shouting.

I would like all light duty vehicles to meet the same noise limits, meaning for the diesel p/u to be quieter.

Thoughts ?

This will just add to the cost of all goods for everybody. Can I ask why?

I'm with Fred.... Why?

Diesel pickup emissions have gotten way more complex in the last 5 years, this would only make them exorbitantly more so. Don't like it? Don't stand near a diesel truck.

pull up in a cackling V8 and watch everyone's windows roll up. LOL.....Car forms a dust plume underneath it with straight down dumps and that much volume coming out the pipes....

try THAT with your exotic...

Diesel pickup owners LOVE to let their trucks idle amd make lots of noise.

I guess they all have bad starters. I see them all time just rattling away with no one in the vehicle.

My favorite diesel trick is when they drop a huge black bomb through their 6" exhaust that fills a cubic kilometer. I see that a lot in Wyoming. They are soooooo cool.

You'd guys hate the sound of my Fcar at idle. No cats, straight pipes out of the headers. Loud at idle. Ear piercing at throttle. At WOT, the car registers about 104db.

I'm sure my Ducati 900 Super Sport would reduce you to tears.

I see it as a noise pollution thing.

The diesel p/u pulls to the curb and idles while the driver does whatever, and as long as he is there, everyone in the immediate area is unable to hear or talk normally.

Kind of like if someone sets down an old-style boom box on the sidewalk and blasts loud rap so that you can't hear or talk normally. Or if someone pulls up on a Harley and sits there, revving through straight pipes. Or throws a big party at their house so that you hear the thudding through your bedroom walls.

How much inconvenience is it reasonable to impose on the people around you?

Depends on the cost and trade offs, of course. I don't know how feasible it is to quiet down your typical 3/4 ton diesel pickup that is idling at the curb while its single occupant talks on his cellphone or whatever he is doing?

I'm not talking about actual commercial work trucks, naturally if you stroll onto a construction site or truck stop, you shouldn't expect anything but noise. I'm talking about diesel p/us when being used as around-town putt putts. They can be tolerably quiet inside the cabin, due to all the soundproofing, but there seems to be little effort to make them quieter to the outside world.

Fcars make good noise; and desmodromic noise is veeeeeery special

diesel noise sucks - esp. the wimps powerstroking themselves


Noise exposure studies show that noise can do a lot of different damaging things to your physiology and behavior. Some acute, and some are chronic. It is not just inconvenience!

Congress passed the Noise Pollution and Abatement Act, more commonly called the Noise Control Act (NCA), in 1972 and it gives EPA power to set limits for ground vehicles (but not airport noise). A city can set noise laws on its own (if the state lets it) and many do. Enforcement is a different issue. PDX can splat a noisy vehicle for up to $5,000 each time, for example. City Code Ch. 18.8 - so get on the horn to the fuzz.

I see that European regulations are 74 dB for cars, 80 dB for commercial vehicles. Diesel cars there are less than 1 dB louder than petrol cars. There are, of course, a lot of diesel cars in Europe, and many of those are mass-market cars at affordable prices.

So obviously it is possible to make a reasonably quiet diesel light vehicle motor, at a reasonable cost. Is there some reason why US diesel pickups can't be quiet(er)?

Gee...I'll bet it's fun making all that racket and pissing people off, huh?
Bottom line is, people (mostly men) like to make lots of noise...and it doesn't even have to be good noise. Look at all the Harley riders who'll spend serious money on exhaust systems just to make their bikes as loud as possible, only to have them wind up sounding like some old clapped-out farm machinery.
It also seems that most people really don't mind having a lot of unnecessary noise around them. Witness a couple of the posts above...hey, what's the problem?

You are wrongly assuming that the motors used in the Diesel pickups are light duty engines... They aren't. For example, both the 5.9 cummins and the Powerstroke are used in 2ton trucks. They aren't anywhere near the same as the little 1.8L VW and Merc diesels. A 3/4ton or 1ton is not a light duty vehicle IMHO.

thing to do is to write to EPA on their web site and ask what their regs are

could be an exception for pickups like the subsidies for gas hogs we used to have...

Its real easy to quiet it down. You just shut the engine off.

Talking about me? I have a 93 Cummins diesel (completely stock). It sure makes some noise, and some people are offended by it. I personally hate the sound Vdubs make but can't say I like the sound of diesels. different sound for different folks. I pay commercial plates, and it does visit construction sites and for most of its life, its driven on the streets empty. People give me the stink eye when I pull up to the curb and make a call or look at a map. Yes, a map. Screw them, its only for a moment. I have a very habit of letting my cars or trucks idle at fueling stations. Main reason it to keep AC going.

Seriously, I've had this same conversation with my sister. She is an avid cyclist (hell, I once was too, when I was much younger) hell bent on cyclists' "rights" in Seattle. She berates my loud Porsche, my loud Ducati, and my loud Harleys. They "shouldn't be allowed" because they are "so annoying". She thinks everything should be as quiet as her bicycle. She complains that I am (and others like me are) "ruining her quality of life".

Well, I'm sorry dear sister, but many feel the same way about bicyclists in traffic. They are not only annoying, but they are also a danger to themselves and everyone around them. Yet I'm "intolerant" when I point this out. She's not intolerant, because "no one likes loud vehicles".

"Can't we all just get along?"... Seems anything we do today has the potential to annoy someone else. Some of us put up with these endless little annoyances (or ignore them altogether) and just carry on. Live and let live. (Oh, and before anyone brings up my oft voiced opposition to bicycles on motorways, let me be clear - they can annoy me all they like. My objection is the physical hazard they present to themselves and the liability hazard they present to the rest of us. Being merely annoying has nothing to do with it.) Others start chanting "ban it ban it ban it..." firmly believing they should never be annoyed or inconvenienced. Yet nothing they do could possibly annoy or inconvenience anyone, much less create a hazard to them.

Such a glaring case of hypocrisy.
