No. How?
AutoblogWe've reported on the silent dangers of hybrids before, and it appears that word of their possible threat to blind people has made it to the halls of Congress. A bill is being introduced today in the House of Representatives that calls for the U.S. Department of Transportation to study whether or not the feds need to regulate a minimum sound level for all cars and, if so, what that minimum should be. If passed, the entire auto industry would have two years to comply. The issue revolves around blind people not being able to hear hybrids while they're running solely on battery power, since they produce much less noise than a normal car with an internal combustion engine. We've heard no reports, however, of hybrids being involved in accidents with pedestrians where the vehicle's silent operation was at fault, but clearly there are many who would like to keep it that way.
The state of Maryland actually passed similar legislation last month, and the industry's own Society of Automotive Engineers already has a task force studying whether or not the decibel level, or lack thereof, produced by hybrids is something we should be worrying about.
Our question is that if such a bill were passed, what technology would automakers use to increase the sound a hybrid makes while running on battery power? Might we hear hybrids with external speakers pumping out the soundtrack of a fossil fuel-burning V8?

Too quiet for deaf people now? That's a bit rediculous.
I agree, it is ridiculous that deaf people can't see yet can hear cars!
I think you meant "Too quiet for blind people now?" especially since blind people was written right in the article.
The too quiet for deaf people issue
Why not an adaption of the HGV reversing warnings?How would they solve the problem? It would probably be something ridiculously annoying like a noise maker on the axle or maybe speakers blasting some tree hugging propaganda or some kind of terrible music. I don't see them trying to make their cars sound like the "enemy," big petrol engines.
DANG YOU PHILLY!!!!!!! Now you have me doing it.You seem to have caught a case of the Philly's! The issue is about blind people.![]()
Why not an adaption of the HGV reversing warnings?
"Warning, warning, this vehicle is moving, stand clear." I imagine New York would be quite harmonic with 100s going off at the same time.
It's no secret that car guys like ourselves aren't known for being hybrid friendly, but come on. Too quiet for blind people now? That's a bit rediculous.
as someone who is not blind i cant really comment.
but i can imagine what it is like to be walking across a street where you cant hear a car and then suddenly have a horn going off in your ear. scaring the living daylights out of you because you thought you'd carefully listened for traffic.
i liken your reaction to white people telling me, a black person, that racism doesn't exit. if you haven't lived it, what do YOU know?
i am 100% for it. an array of sounds could be available. from a beeping to a v8 sound. limit it to something that can be heard from 30 yards.
If it sounds like anything other than a car engine and I can hear it from my house it is not cool.i am 100% for it. an array of sounds could be available. from a beeping to a v8 sound. limit it to something that can be heard from 30 yards.

And like I said earlier, I don't see the benefit. No one has been hit because of this yet. So we are legislating against things that may or may not happen now just because a special interest group complained?
This is just a waste of taxpayers money in my opinion.

The thing is thought, it's not the audible sound the blind person would notice, its the lower, bass like frequencies they'd pick up on. So says my mum who works with deaf and blind children.I think the most cost effective solution would be a playing card ticking against the spokes on the wheel...
But seriously... lots of cars are "quiet". Quiet in the sense that you can't really hear them over the din of traffic in the city. Or the airconditioning unit across the street... or...
I remember a time, maybe seven years ago, that I started up a Maxima (Cefiro) V6 in the showroom. The guy standing behind the car walks up and asks me to turn it on, so he can see the gauges lit up. He was pretty surprised that the car was on, already.
Now take a car that quiet... put it on the street, surround it with noisy, barking old cars... isn't that a danger to blind people?
Why don't we ask the blind ourselves?
This made me lol.I think the most cost effective solution would be a playing card ticking against the spokes on the wheel...![]()
I don't think the issue here is in a city full of cars. US cities with these situations have already implemented visually impaired aids, such as audible sounds from crosswalk lights and so forth. In that instance I believe that unless they have DareDevil style sonar vision one car from another won't do any good.Now take a car that quiet... put it on the street, surround it with noisy, barking old cars... isn't that a danger to blind people?

I have noticed that: engine noise is barely audible nowadays. Even without a "Performance" exhaust the Nova and Cabiro make a good deal of their own mechanical noise at Idle. Newer cars kind of make a whine and low purr. I find it terribly irritating.
Every early adopter I know of hybrid technology loves their 1st gen hybrid because it shows they did it before it was trendy and that they care about the environment more than the others.

You know, you are right. And I know tire noise can be affected by hwo well the tread lines up. So, if we mess up the tread pattern a bit it shoudl fix teh problem.I don't understand what the issue is, most of the noise from a car typically comes from the tires, not the engine if the Modern Marvels episode about highways is anything to go by.
Not everyone can have the nice cars we have.Are we talking about modern engine noises being annoying because they don't have all that clanking and banging of an older engine? I personally don't mind the low purr my car gives out at low revs, the whine it gives at higher engine speeds and the growl I get under heavy acceleration. Not hearing the engine when the car is on is an issue though. I was always bothered when I rode in my neighbor's Highlander hybrid that shut the engine off at stops.
AutoBlogGreenHow much energy would the U.S. save if ten percent of the population switched to hybrids
We here at AutoblogGreen are big on technology that can lower environmental impact. Hybrids are widely touted as one way of doing that although some are much better at it than others. With over a million of the most popular hybrid, the iconic Prius, being sold there must be a noticeable decrease in the amount of gas being burned by Americans, right? Have you ever wondered how much gas would be saved if we all drove a Prius? About half, unless we all drive like Danika. OK, that's an unlikely scenario. How about if 10 percent of the car-driving public used some kind of hybrid? With 2.2 percent of the cars sold last year being hybrids it seems we are on our way to that small milestone.
After pulling out my slide rule (and then putting it away after I remembered I never did learn how to use it), calculator and a copy of the I Ching, I set out to solve this problem of the ages. According to the Department of Energy (DOE) we burned through 9,290,000 barrels (390 million gallons) of gas a day in 2007, which is about half of all finished petroleum used - so we're not even talking about diesel or aviation fuel. Using advanced algebraic formulae which required the participation of all of my fingers and toes, I've deduced we could save about 6,285,000,000 gallons each year (around 16 days worth of gas) if ten percent of us drove hybrids. A big number indeed but one I hope we can soon surpass.
