Addressing the danger of too-quiet electric cars, with a little help from Blade Runner

By | September 21, 2009, 8:01 AM PDT

The problem with electric cars? They’re too quiet.

The growing popularity of the electric car may be beneficial for the environment, but their near-silent operation means the vehicles may also be a dangerous threat to pedestrians.

Some groups, including advocates for the blind, children and the elderly, say pedestrians may fail to notice approaching electric vehicles. To address those safety concerns, transportation agencies in the U.S. and Japan may mandate artificial sounds for the vehicles, reports Bloomberg.

Car makers such as Nissan and Toyota are researching sound as silent models continue to enter the auto marketplace. But instead of simply reincarnating the sound of a gasoline-powered engine, car makers are consulting musicians to invent something new.

Bloomberg reports on Nissan’s activity:

The company consulted Japanese composers of film scores. What [engineer Toshiyuki] Tabata and his six-member team came up with is a high- pitched sound reminiscent of the flying cars in “Blade Runner,” the 1982 film directed by Ridley Scott portraying his dystopian vision of 2019.

“We wanted something a bit different, something closer to the world of art,” Tabata said.

The sound system would automatically activate when the car starts, and shut off when the vehicle reaches 12 miles per hour, according to the engineer in the article.

The U.S. National Highway Traffic Safety Administration is currently analyzing data on crashes involving pedestrians and hybrid vehicles and plans to issue a final report by January.

The National Federation of the Blind has urged car makers to incorporate noise into the designs of hybrids and plug-in electric vehicles.

But with little oversight, it’s anyone’s guess what the engine of the future will sound like.

Tokyo-based electronics manufacturer Datasystem Co. makes a device selling for about $140 that emits 16 different sounds, including a cat’s meow, a cartoon-like “boing” and a human voice saying, “Excuse me.”

Despite a lack of regulation, Nissan said it may equip its Leaf electric car with a sound system in time for the car’s introduction next year. The addition will increase the car’s sticker price, which has not yet been announced and will begin sales next year in the U.S., Japan and Europe.

General Motors has said it will introduce its Volt plug-in electric car by November 2010, and Toyota said it will introduce a battery-powered vehicle in 2012.

RE: Addressing the danger of too-quiet electric cars, with a little help from Blade Runner
the person who wrote this article has too much time on his hands; worrying about something that really does not exist. the deaf don't hear cars coming now. we just have to look about us and keep our eyes open. the blind rely on guide dogs. if they go out alone thay are really taking a chance and listening for auto sonds is not going to cut it.

there are so many really tough problems tpo solve in our everchanging society, why waste tiime and energy on this nonproblem.

Contrary to STILT21, this is very dangerous and not only for the blind.... most people rely on sound as a directional safety device.

Speaking from experience, in both times I have had with electric cars, it was the drivers that assumed I could hear them coming.

These incidents did not occurr on a main road, but in parking lots, where the drivers were pulling into parking spots.

stilt21: The article never mentioned the deaf. I have seen the blind navigating streets without a guide dog.

I'm not sure how Nissan's sound system would help much of the stated problem in the article when it turns off at 12 mph...I don't know of anyone driving around slower than that. Sounds like that is just a warning system that the car is starting to move, doesn't help once you are driving down the street. Of course I wouldn't want to drive an electric car that makes an annoying sound while I'm driving. Maybe they should play ice cream truck music just to be equally annoying to everyone.

The sounds of silence............whatever sound should become the recognizable melody for an on coming electric car, it will still be the sweet hum of progress.

RE: Addressing the danger of too-quiet electric cars, with a little help fr
What a dumb article. It would be wonderful to have silent cars, the
great curse of any city is traffic noise. I'm living in China and most
people ride electric bikes - can't hear them, but people get used to that
and look out for them. Haven't seen an accident yet. But are electric
cars being made any safer to drive than petrol, no, of course not, that
would be too sensible. They'll kill and maim just as many of us as the
good old piston jalopies. And are electric cars going to stop pollution?
No, they're just going to remove it to the coal power stations. Are
electric cars a good idea? No, there's the recharge problem and unless
you have a battery exchange machine in your home you're stuck with a
recharge time of several hours. Plus they are not cheap to make. The
real answer has been around for a long time and it is free - air.
Compressed air vehicles are already showing they can match petrol
driven vehicles in all aspects and there is no pollution associated with
them whatsoever. Air is free, and if you have to use a compressor,
solar cells are enough to power such devices. Why not spend some
time writing an article on that. Obviously governments and car
manufacturers are ignoring air vehicles because it is difficult to make
money selling them and there is no fuel infrastructure to tax. This
planet is going into meltdown, threatening the survival of billions, so do
we really care if a dumb pedestrian wearing an ipod doesn't look both
ways before stepping onto a road? Or do we care if we don't make
power stations burn even more coal so that we can drive electric cars?

Cars are already pretty quiet: with a lot of road surfaces, I hear the tires before the engine. So if this gimmick is necessary for electric cars (doubtful) it is needed for the old kind too.

Another ridiculous waste of money.

Sighted persons should do what they're supposed to do; Stop, look both
ways and proceed when safe. The blind should have a guide dog anytime
they are close to a highway.

The incompetent will have a shorter lifespan; as has been the case for
millenia.

Make them sound like cars
If the point is to make the world safer by activating the cues that rell us a cars is around and moving, them make them sound like existing cars, don't make them sound like dozens of other things.
like, Duh.

RE: Addressing the danger of too-quiet electric cars, with a little help fr
stilt21 - ignorance is one word that comes to mind... "the deaf don't
hear cars coming now" - Yes, but the deaf can also see. "We
just have to look about us and keep our eyes open" - They can't
because they are blind. "The blind rely on guide dogs" - No, very
few in fact due to the expense - most rely on the sounds around them
and their canes - actually they call the technique "Cane Travel".

What we are discussing here demonstrates why we need to be more
concious about our enviroment. Here we have an example of how
changing the enviroment or introducing "new species" has an impact on
the Eco-system, in this case the human eco-system. Electric cars are
growing in numbers - and becuase of this more people (particularly the
blind, children and the elderly) are failing to notice the approaching
electric vehicles and are being injured.

There is a lesson in this for all of us...

Cheers

RE: Addressing the danger of too-quiet electric cars, with a little help from Blade Runner
The concern is real, last year I saw an interview with Diane Keaton who accidently drove over her very large cat with her prius, it was so quiet the cat didn; hear it coming, (cat is OK just a few bruises).

S in the interiim we need some sound to alert people and animls of the presence of a vehicle

RE: Addressing the danger of too-quiet electric cars, with a little help from Blade Runner
I agree with cjcronin, while the sound from cars is one issue the whole nature and hype of the electric car is joke. It's meant to reduce pollution - NOT, it's meant to reduce relaince on fossil fuels - NOT.

Electric cars need recharging normally from coal powered electricity generation. So pollution goes from the exhaust pipe to the power station, no reduction in pollution and no reduction in reliance. How quiet are governments and cars manufacturers aboput this obvious flaw? VERY!! Why? Because for them it is nothing to do with real concerns about pollution, its about image and profit always!!

And as for this "sound idea" it is not a sound idea to have a whole confusion of different sounds available. As some one put it, just use the normal sounds we are currentl used to and everyone will instantly recognise this. Playing tunes and other sounds will just confuse people, especially those disabled or old and easily confused. Tyre noise and a soft engine noise is enough and is readily recognisable. Just KISS it ( Keep It Simple Stupid!) - complicated solutions just complicate things.

RE: Addressing the danger of too-quiet electric cars, with a little help from Blade Runner
Has the author of this silly article ever heard of those SILENT KILLER BICYCLES. You know the ones with 2 wheels, pneumatic tires and pedals to propel them forward. Is there a conspiracy suppressing the statistics of all those people killed and maimed by these silent killing machines and their blind drivers?

A poorly written article
Too bad the author blew it in his article about who would benefit the most. He had the right intentions, but lousy delivery.

Bottom line is, I use my sense of hearing as well as sight to be on the lookout for oncoming vehicles when I'm walking. I'm sure I'm not the only one who does this. Electric cars are a danger since they no longer give an audible signal to their presence. People are going to get hurt, or even die, because no one addressed this problem before now.

In this regard, the deaf have an advantage over the rest of us. They only depend on their sense of vision to warn them and will be taken surprise by an electric like the rest of us can.

RE: Addressing the danger of too-quiet electric cars, with a little help from Blade Runner
It would be a dream for me in to have a all the cars to run silent. Being in india and in bangalore, every single person over here would like all the veichele to go silent.. When we are thinking here in tht way, and car manufacutrers spending money to increase noise in a car..... No words to express....

RE: Addressing the danger of too-quiet electric cars, with a little help from Blade Runner
Some sort of standard warning sound is a good idea. A high-pitched sound is not the best choice,however; that's the first part of their hearing people lose. Use something Grandpa can hear, too!

As for the idea that electric cars don't reduce fossil fuel use, that's totally wrong. Electric motors are far more efficient for the way power is needed to propel a car - starting and stopping, running at variable speed, needing high torque from a standing start. Plus, electric vehicles can use regenerative braking, recapturing power and putting it back in the battery when they slow or stop.

Electric power plants are vastly more efficient at converting fossil fuels to power than internal-combustion engine vehicles. These efficiencies, taken together, far outweigh the loss incurred by converting kinetic energy to electricity, then back to kinetic energy. Even if fossil fuels are burned to produce the juice to charge electric cars, a lot less is burned than would be if the cars directly burned fossil fuel.

Not all electricity is produced by burning fossil fuels, anyway - and more is coming from clean, renewable sources all the time. As this trend continues, the carbon footprint of an electric vehicle will get smaller - something that will never happen with your old gas-guzzler.

They had it right in the "good old days."
Have someone walk in front of the vehicle carrying a lantern...
Maybe they should equip these vehicles with those little devices that are supposed to warn deer of oncoming vehicles.
Then, of course, there are those pesky kids with scooters, skateboards and skates, not to mention those with battery operated scooters.

ASSOCIATES AT JADE MT. APPROPRIATE TECHNOLOGIES, IN 1996, CAME OUT WITH A BOOK WITH PLANS THAT WILL ALLOW AHANDYMAN BUILD AN ELECTRIC CAR FOR UNDER $1000!!!
