Getting Quiet Cars to Make Some Noise

A lot of people who drive gas-electric hybrid cars love how quiet they are. But others say hybrids are so quiet they’re hazardous. People in the blind community say they can’t hear hybrid cars coming… and they’d like to have sound added back into the cars. Rebecca Williams has the story:

(tap tap tap of white cane)

Fred Wurtzel has excellent hearing but he can’t see.

He can tell by the echo from his white cane when he’s gotten to the edge of a building or the corner of a city block. And he knows cars by their engines.

(sound of car rumbling past)

“That car has a tweety bird under its hood, a loose belt or whatever it was. Now, there was a car going the other direction. (sound of truck going past) That’s probably a UPS truck.”

But he can’t hear hybrid cars – at least not until they’re right at his feet. That’s because the electric motor is very quiet. And when a hybrid comes to a stop, the engine shuts off.

“If you don’t know there’s a hybrid car there waiting, it may start turning and you may step into its path and not even be aware that there’s a car coming around.”

Wurtzel is president of the Michigan chapter of the National Federation of the Blind. He says the blind community wants some sound added back into hybrid vehicles.

“’Course I grew up in the 60’s so a nice Mustang or something like that would be good (laughs)… just a sound that would let me know that the car’s accelerating or the car’s decelerating – whatever a normal vehicle would sound like.”

Well that’s one idea.

Patrick Nyeste has several ideas. He’s a researcher at North Carolina State University. He tried out 18 different sounds on his test subjects.

Everything from sirens (sound of siren)… to whistles (sound of whistle) … to engine sounds (sound of engine).

“I had a horn from a Beetle – so it’s, ‘meep meep,’ and I would just get giggles from that.”

But, he says to make a quiet car safer, the sound needs to be continuous – like a traditional car. That means some sounds can get annoying really fast.

(sound of continuous beeping)

Yeah that’s enough of that.

Nyeste says that engine noise we heard earlier was one of people’s favorites. They also liked white noise (sound of white noise), and the hum sound (sound of humming). He says that’s because we’re used to hearing those kinds of sounds when a car goes by.

He says a sound added to a hybrid also has to be loud enough to be heard above lawn mowers and garbage trucks.

“You want to make sure that the noise is heard, especially by the blind around corners, around objects, I mean some of these sounds can get masked and that’s important information to know where an object or a vehicle is.”

But some people are worried about adding sound to our cities and suburbs, they say they’re already so noisy.

Lotus Engineering says it has a solution for that. They added a four cylinder engine sound to a Toyota Prius. But the volume’s adjustable.

Colin Peachey is an engineer with Lotus.

“You could set the sound to be higher in certain circumstances or quieter in other circumstances. We could actually make the sound to be whatever level we fancied.”

And you don’t have to hear the sound inside the car.

There’s also a startup company in California – Enhanced Vehicle Acoustics. It’s designing a similar system for hybrids.

But it’s not clear how soon quiet cars might start making noise.

Spokespeople for Toyota and the Big Three say their companies are working on solutions. And some states and members of Congress have been talking about requiring hybrids to make some minimum level of sound.

Then, automakers will have to figure out exactly what a hybrid sounds like.

A study of more than 18,000 farmers shows a link between neurological symptoms and
long-term exposure to agricultural chemicals. The Great Lakes Radio Consortium’s Erin
Toner reports:


The study by the National Institute of Environmental Health Sciences included data on
farmers in North Carolina and Iowa. The farmers answered questions about lifetime
exposure to herbicides and insecticides, and about their history of neurological
symptoms.


Dale Sandler is chief of epidemiology for the NIEHS. She says 20 percent of the farmers
in the study experienced 10 or more neurological symptoms – some years after the
exposure.


“Dizziness, light-headedness, tremor, loss of vision, headache, fatigue. These are, as you
know, non-specific and people have these symptoms unrelated to pesticides, but they’re
also classic signs of pesticide poisoning.”


Sandler says the goal of the study is to find ways farmers can apply pesticides in a safer
way. She says future studies will look at links to long-term neurological diseases, such as
Parkinson’s.

‘Land Bank’ Reinvests in Inner City

One community is fighting its problems of abandoned lands and unpaid property taxes. Those problems have led to a decaying inner city and increased suburban sprawl.

One community is fighting its problems of abandoned lands and unpaid property taxes.
They’ve led to a decaying inner city and increased suburban sprawl. The new tool the
community is using is called a “land bank.” It uses a unique approach to try to fix up
properties that otherwise often would be left to deteriorate. The Great Lakes Radio
Consortium’s Chris McCarus reports:


(sound of work crews operating wood chipper)


Cleanup crews are sending downed branches through a wood chipper on a vacant lot.
They’re also removing tires, used diapers, car seats, sinks, old clothes and dead animal carcasses.
The workers are from the Genesee County Land Bank in Flint, Michigan. They’re trying to
make abandoned property useful again. Dan Kildee is the Genesee County Treasurer and the brains
behind the land bank. He thinks this new approach can recover unpaid property tax money and help
improve the Flint Metro area.


“The community gets to make a judgment on what we think we should do with this land. We get
to take a deep breath.”


Empty lots and rundown homes have been multiplying for a generation. That’s left the city of
Flint in a terrible economic state. But the land bank is beginning to change things.


Until just three years ago, Michigan was like most other states. No one had come up with
a solution. The state would auction off a city’s tax liens. Then conflict between the tax
lien buyer and the property owner could go on for up to seven years. In the meantime,
properties were left to neglect and often vandalized.


Under this new program, the treasurer’s office forecloses on a property and hands it over
to the land bank, which acts as the property manager. The land bank might then demolish
a house; it might throw out the owner and let a tenant buy it; or it might auction it off
to the highest bidder. A private investor can’t just buy a tax lien. He has to buy the
property along with it and take care of it.


The land bank is financed in two main ways: through fees on back taxes and through sales
of the few nicer homes or buildings the land bank acquires that bring in relatively big
profits. Treasurer Dan Kildee says it makes sense to take that revenue to fix up old
properties and sell them to people who deserve them.


“There is no system in the United States that pulls together these tools. Both the
ability to quickly assemble property into single ownership of the county, the tools
to manage it and the financing tools to develop that property.”


The land bank program hopes to change the perception of Flint. As thousands of abandoned
homes, stores and vacant lots become eyesores, people and their money go other places,
usually to build more sprawling suburbs. The perception that people are abandoning the
inner city then speeds up that abandonment. Many people who can afford to leave the city do.
And those who can’t afford to move are left behind.


According to data gathered by the research group Public Sector Consultants, Flint has the
state’s highest unemployment and crime rates and the lowest student test scores.


Art Potter is the land bank’s director. He thinks the downward spiral can be stopped.
When it is, those folks in the central city won’t have to suffer for still living there.


“Even though the City of Flint has lost 70,000 people in the last 30 years, the people who
are still here deserve to have a nice environment to live in. So our immediate goal is to
get control and to clean these properties now.”


Urban planning experts are watching the land bank approach. Michigan State
University’s Rex LaMore says Flint is typical of Midwestern cities whose manufacturing
base has shrunk. Private owners large and small have left unproductive property behind.
As the land bank steps in, LaMore says it’s likely to succeed and become an example that
other municipalities can follow.


“They can begin to maybe envision a city of the 21st century that will be different than
the cities of the 20th century or the 19th century that we see around the United States.
A city that reflects a more livable environment. So its an exciting opportunity. I think
we have the vision; the challenge is can we generate the resources? And the land bank model
does provide some opportunity to do that.”


But the land bank is meeting obstacles. For example, the new mayor of Flint who took over
in July canceled the city’s existing contracts. A conservative businessman, the mayor is
suspicious of the city’s past deals. They included one with the land bank to demolish 57
homes. This has slowed the land bank’s progress. Its officials are disappointed but they’re
still working with the mayor to get the money released.


(sound of kids chatting, then lawn mower starts up)


The weeds grow rampant in a neighborhood with broken up pavement and sometimes
no houses on an entire block. It’s open and in an odd way, peaceful. Like a
century-old farm. It’s as if the land has expelled the people who invaded with their bricks,
steel and concrete.


In the middle of all the vacant lots, Katherine Alymo sees possibilities.


“I’ve bought a number of properties in the auctions from the land bank and also got a side
lot acquisition from them for my house. My driveway wasn’t attached to my house when I
bought it. And it was this huge long process to try to get it from them. But they sold it
to me for a dollar. Finally.”


And since then, she’s hired people to fix the floors, paint walls and mow the lawns.
She’s also finding buyers for her properties who want to invest in the city as she has.
Together, they say they needed some help and the land bank is making that possible.

Junk Cars Become Environmental Art

We’ve come a long way since Henry Ford’s black Model T. Cars of every shape, size – and color – now practically dominate American life. Which poses a problem – what to do with the cars once they’re piled high in junkyards. A recent public art project offered one passionate recycler a chance to reuse junked cars in his art.

We’ve come a long way since Henry Ford’s black Model T. Cars of every shape, size – and color
– now practically dominate American life. Which poses a problem – what to do with the cars
once they’re piled high in junkyards. A recent public art project offered one passionate
recycler a chance to reuse junked cars in his art. The Great Lakes Radio
Consortium’s Joyce Kryszak has this story of “Art on Wheels”:


The American landscape is filled with automobiles. Lines of fancy molded steel are everywhere
– in parking lots and bumper to bumper along the highways. Or, as Canadian folk singer Bruce
Cockburn once observed, a kind of “sheet metal ballet.” But, sadly, when the dance finally ends,
there’s nothing left but junkyards of crushed steel. A recent community art project suggested that
re-use could be an answer to the old environmental debate of what to do with all the junk.


(sound of kids at the art show)


Dozens of artists were asked to come up with their own unique ways to re-use at least some of
that automotive scrap for the recent “Art on Wheels” Project. Art teacher Bruce Adams describes
what he and his high school students call the “Environmentally Friendly Car.”


“There’s a picket fence on each side. The front we call the front lawn, because the surface is a
big, grass lawn, with a bird house, so the birds can live there over the summer. Then the back of
it, we call the backyard, it’s a garden, it’s a got a pond, it’s got a stream running down to the pond
– it had fish living in there all summer.”


Adams says they built the car as sort of an ironic commentary on the whole American dream
thing. That’s what many of sculptures in the exhibit were designed to do – to make a statement.
Other sculptures, such as the cement truck chicken, were simply intended to be outlandish. But
for one of the exhibit artists, Doug McCullum, re-use isn’t a novelty. It’s a lifelong expression.
You might even say an obsession.


“My sister broke her femur…I made a lamp out of her steel leg splint. It was a little strange
thinking that, you know, this thing spent six months in my sister’s leg –
but she kind of enjoyed the lamp.”


McCullum is, well, shall we say, passionate about re-use? Okay, so you might even call him the
Dr. Frankenstein of the junkyard. His Gremlin car sculpture from the exhibit features some of
his junkyard creations. They’re popping out of the roof, the hood, the doors and the gas tank.
Come meet Scratch, Knock, Guzzle, and the rest of the Gremlins gang.


“The car is covered in a wide variety of monsters, all named after things that go wrong with your
car – henceforth the name Gremlins. They are all made out of various things like air compressor
tanks, and old recycled drive shafts, and snow blower hoods, and old air tanks.”


No, McCullum isn’t an auto mechanic, or a junk dealer. He’s an architect by trade, who likes to
create recycled art in his spare time. But McCullum doesn’t have to go far for re-use materials
when he begins a project. He just walks downstairs and scrounges around in his basement.
McCullum says he saves everything – and he’s especially partial to automobile salvage.


“I have so much steel, and so much stuff that I’ve recycled in my basement that it would take a
small crew to move that stuff out, and that’s just the way I create.”


McCullum says there are plenty of worn out or broken parts from his own cars down there. And
he’s never one to pass up somebody else’s cast off muffler or tire tread abandoned at the side of
the road. McCullum hauls it all home for his next project. And if he does run into roadblock
while creating? McCullum says he loves to go shopping – at the junkyard of course.


“It’s like shopping at the mall for me. I like climbing through the piles, and digging through
something, and I get a lot of enjoyment out of it. Like, oh… this could be a great head, and sit
that aside… I go looking for a part and I come out with like a couple hundred pounds worth of
steel. Like, yeahhhh, like there was a big sale at the mall and I’m coming out with the spoils of
my labor.”


But make no mistake, for McCullum re-use isn’t an idle past time, it’s a professional and personal
commitment. As both an artist and an architect he says he believes in the beauty and the
possibility of preserving everything. McCullum says things can and should last. He says it’s
purely a matter of vision.


“Basically, anything that is discarded can be re-used in a wide variety of ways, just people don’t
have the vision or that kind of mentality to really think in a different way. And that’s really what
this whole project is about – the Art on Wheels thing in general – you can re-use everything.”


(sound of kid yelling, “Look a bug car! There’s a bug on top!”)


MCullum says the unusual automobile inspired sculptures were fun to make – and to look at.
Mind you, he doesn’t expect to see gremlin cars or cement truck chickens roaring down the
highway anytime soon. But McCullum says hopefully the exhibit will help turn people on to the
possibilities of recycling.

ARTISTS ‘RE-VISION’ THE GREAT LAKES

People who study the natural world often do field research. They go to learn about plants, animals, and the ecosystems we live in. But scientists aren’t the only ones who can make use of time spent studying the outdoors. The Great Lakes Radio Consortium’s Tamar Charney reports.


A group of students from the University of Michigan have stopped spreading sand on the floor and hanging sticks from a gallery ceiling to watch a video….


(video sound of slosh slosh on the trawl line a bass)


The tape is of a trip they took…to sail, to camp, to hike, to learn about the aquatic life in the great lakes….


(video sound of phylo arthro arthrabida crustratia (fade under))


…And to do some field research. But these students aren’t scientists…. they’re artists. And they are in the process of putting together an art exhibit.


“This exhibit is based on a semesters worth of investigation that art class has been pursuing.”


Joe Trumpey is a professor of art at the University of Michigan. He also teaches scientific illustration. And for years he’s been taking those students to the dessert, and even the jungle, to learn in the real world — instead of the classroom — about flora and fauna and the cells and structures they draw. Now he’s bringing this same method to a studio art class – to encourage these students to develop a relationship with the ecosystems of the Great Lakes region.


“Like any interpersonal relationship, a friendship, a marriage, anything you need to spend time and communicate with each other and to sit in a studio and think well I can make this all up in my head and its all fine. I’ve seen it in books. I’ve seen the pictures, but it isn’t the same as being out there and feeling the wind and the smell and the elements and everything else that’s associated with a particular environment.”


But they did more than just experience the land. Gerry Mull is a graduate student in Fine Arts and a member of the class.


“We explored a lot of environmental issues around the Great Lakes, talked to sea grant people and people doing different kinds of about ecological problems with the Great Lakes.


It was only after learning about fisheries, the food chain, the history of the Lake Michigan sand dunes, the economic impact of Great Lakes shipping, and the plants and animals here that the students got down to the business of creating art out of what they learned.


Gerry Moll has hung long pieces of what looks like brown grass from the ceiling. 24 big primitive forms that resemble sturgeon hover over sand he’s spread out on the floor. He says he hopes his piece creates a longing in the people that see it for the huge number of these fish that used to swim in this region.


“A kind of longing, a dream, a vision of something better, of more sturgeon in the Great Lakes, of what its like and how important it is to have these other beings in our lives. And a lot of fields do that but I think art does it in a special way.”


What these students are doing falls loosely under the category of ecological art — there’s a number of branches of this field – There are artists who actually restore the environment – creating fish habitats or cleaning up a Brownfield as their art. Then there are artists like Gerry Mull who are trying to rekindle our concern for nature. The University of Michigan is in the process of developing an art curriculum that focuses on the environment. And the University of Michigan isn’t alone. Environmental issues are popping up in arts schools and art classes of all levels. Don Krug is a professor of art education at Ohio State University.


“I think it is being taught more and more in higher education and I think it finds its way into art education in public schools in terms of units of study but there is a growing interest and I think if you look at universities throughout the United States there are more and more programs addressing these issues.”


Krug along with the Getty Museum has even developed on-line curriculum materials to help teachers get their students involved in creating art that draws on environmental and ecological issues. University of Michigan Art Professor Joe Trumpey says it only makes sense that art would be addressing something as fundamental as the health of our planet.


“The environment is something that all of humankind shares. Contemporary North American Society has moved away from family farms and is spending time outdoors. Long term relationships outdoors mean a weekend here and a weekend there I don’t think is the same sort of relationship as we had 100 years ago. So, for me, to build work that highlights that, and maybe make it become more into the central focus of peoples lives and understanding about where their food comes from and the relationship between them, and the animals, the plants, the land and the air becomes very important.”


And for artists to create meaningful art about the natural world, Joe Trumpey says they are going to have to immerse themselves like a scientist in the field. Studying the ecosystems around us through paint, clay, charcoal, and the other tools of the artist. For the Great Lakes Radio Consortium, I’m Tamar Charney.
