When Congress returns from its August
recess, one of the tasks on the agenda is
confirming President Obama’s pick to head
the National Park Service. If confirmed,
Jonathan Jarvis will have some tough
decisions to make about what kinds of tourist
attractions to allow in the parks. Jessica
Robinson reports on the latest proposal to
add aerial sightseeing tours at a National
Park in Oregon:

Nearly 8,000 years ago, Mount Mazama spit out ash and lava and collapsed in on itself, leaving what became Crater Lake.

Park Superintendent Craig Ackerman says the stillness of the blue waters is matched only by the stillness in the air.

“You can stand on the east flank of Mount Scott and you can absolutely hear the wind whispering through the white bark pines and the hemlocks.”

It’s true – there are moments when it’s just your footsteps, the wind, and the birds.

But then, at the popular viewpoints, there are the other species you find at many national parks: like Toyotas, Winnebagos, and Harleys.

Now, a company up the road in Bend, Oregon, has a proposal that could add one more sound to the mix.

(sound of a helicopter)

Leading Edge Aviation has put in an application to offer as many as 300 helicopter tours a year around the edge of Crater Lake. Travis Warthen is the company Vice President.

“I mean, it really is a majestic sight to see. And, the noise level is less than that of a car – you know, definitely motorcycles, RVs, the bus tours. I mean, it’s difficult for us to understand the huge opposition.”

At 1,000 feet up, he says, the choppers sound to someone on the ground, about as loud as a normal conversation.

“So you say, ‘it’s already compromised by the motorcycles and the motor-homes, so what’s wrong with a little more?’”

That’s Scott Silver. He’s executive director of Wild Wilderness, a group he started with a friend to monitor motorized recreation on public lands.

Silver sits in his back yard, just across town from the aviation company proposing the tours. He says National Parks should provide a respite from some of the noise we’re used to in everyday life. As he explains this, a passing helicopter interrupts our interview.

(sound of a helicopter)

“That’s actually the helicopter from the hospital. But, okay, it’s no big deal really in town. It’s just a distraction. But everyone still stops and looks up if it’s flying over a national park. And really, why should visitors have need to look up to listen to sounds over head?”

National Parks advocates worry that helicopter flights at the Grand Canyon, Glacier National Park, and others are making commercial tours the norm for parks visitors. They’re hoping Obama’s pick to lead the National Park Service, Jonathan Jarvis – a former Crater Lake biologist – will reverse the trend.

But here’s the rub: there’s nothing stopping you from flying over any National Park right now – if you have a private plane.

And Jeff Allen, head of the Crater Lake Trust, wonders if that’s fair.

“There’s a part of me that feels like, if you’re going to allow it at all, I’d rather see regular folks be able to have that experience, than have you have to go out and own a plane or know someone who owns a plane.”

Aerial tours of Crater Lake won’t be offered any time soon though. There’s a hefty backlog of similar requests at other parks – and they’ll all have to go through not one but two federal bureaucracies: the National Park Service and the FAA.

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:

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.

Driving Down Road Noise

Whizzing tires, whining engines and booming car
stereos are just about everywhere. Those sounds are a
form of pollution, and can affect the way we feel. Kyle
Norris has this story:

The engineers at Chrysler are hard-core about noise.

Right now they’re inside a high-tech studio.
And there’s a car on rollers.
The engineers are trying to pinpoint the noises that a driver would hear.

Inside the cabin it’s pretty quiet (quiet sound inside cabin).
But outside, well… Engineer Taner Onsay explains.

(yelling over whirr of tires) “This is how it sounds outside. See, I cannot
communicate with you, with this sound. Inside this would be totally unacceptable.”

Cars that are quiet are the inside are a huge selling point in the auto biz.
But what about the sounds that a vehicle puts into the world?

Like road noise.
What are people doing about that?

Not a whole lot.

Story goes, there used to be a federal office that dealt with noise.
It was the EPA’s Office of Noise Abatement and Control.

But President Reagan shut that baby down in 1982.
Basically to save on cash.
The idea was that state and local governments could deal with noise.

The noise office did a lot of good things just to help protect our ears.
It had noise standards and regulations – on the books.
And the office was just a really good resource for state and local organizations, and also for people who were just having problems with road noise.

But since it’s been gone…

“Well a lot of the local noise-control programs at the city and county level just dried up
and blew away. It’s hurt the noise program tremendously throughout country.”

That’s Bill Bowlby.
He’s president of an engineering company that consults about road noise.
He’s also worked for state departments of transportation and for the Federal Highway
Administration.

He says that state departments of transportation are concerned about road noise.
And that they’re thinking about things like quieter tires and quieter pavements.
And about not building residential areas near highways.

But states are only required to do so much about road noise.

For example, when states are widening or building highways and using federal money –
which they almost always are – they’re required to study road noise and obey certain
standards.

But when it comes to road noise coming from an existing highway, it’s totally voluntary if
a state wants to deal with it.

So you get a range of how different states deal with it, which they call retrofitting.

Bill Bowlby that says although some states take the issue very seriously…

“…other states have had little interest in idea of retrofits usually because they’re looking
to spend their limited amount of money on highway related projects.”

And the kicker about road noise is that it can seriously, seriously affect people.
For people who live near noisy roads, it can make their lives miserable.
Plus it can make it hard to concentrate as a driver.
And to hear the vehicles around you, like motorcycles and other sounds, like sirens.

Dennis Weidemann is a guy who’s thought a lot about all this.
He wrote his thesis about road-noise.

He says that road noise isn’t dramatic or flashy.
So it doesn’t grab our attention.
And road noise does not have a villain, so we’re all responsible.

Weidemann says it can seem hopeless to people.

“They know they don’t like it but they don’t know how it effects them. And if you don’t
know that, you just get the impression, well, it just bothers me, I’m weird, I’ll let it go.”

Noise experts say we need to re-open the federal noise office.
Or something like it.
And we’ve got to figure-out how to make things quieter.

This is starting to become a hot topic in the pavement industry, where different
businesses are trying to one-up their competitors by making the quietest pavement.

But for car companies there’s really no incentive to make cars that are quieter on the outside.
And right now there are no regulations of how quiet a car needs to be when it comes off
the assembly line.

Although that’s not the case in Europe,
where vehicle noise regulations are much more strict.
And where the whole subject of road noise is taken a lot more seriously.

The Foibles of Suburban Lawn Care

  • Although a well-manicured lawn offers certain benefits... not everyone thinks it's worth the effort. (Photo by Ed Herrmann)

One of the great rituals in suburban America is mowing the lawn. A
manicured lawn seems to say that the house is well cared for, that it belongs
to the neighborhood. Great Lakes Radio Consortium commentator Ed
Herrmann wonders whether this obsession with the perfect lawn is worth the
effort:


(sound of evening insects)


It’s a late summer evening and at last I can go outside and enjoy the
sounds of the neighborhood. There’s a little breeze, the air is cooler. The
chorus of insects is soothing, gentle but insistent, an ancient throbbing
resonance. Much better than during the day…


(roar of lawn machines)


Summer days in the suburbs are the time of assault, when people attack their
lawns with powerful weapons from the chemical and manufacturing
industries. Anyone who uses the words “quiet” and “suburbs” in the same
sentence has never been to a suburb, at least not in summer.


It takes a lot of noise to maintain a lawn. Besides the mower, you’ve got edgers, trimmers,
leaf blowers, weed whackers, core aerators, little tractors, big tractors, slitting
machines. I don’t know whatever happened to rakes and hand clippers. One
thing’s for sure. This quest for lawn perfection wouldn’t be possible without
the industrial revolution.


(machines stop)


So where did we get the idea that a house should be surrounded by a field of
uniform grass kept at the same height?


Well, with apologies to the Queen, I’m afraid we must blame the British. It
seems that, along with our language, our imperial ambitions and our
ambivalent morals, America also gets its notion of what a lawn should look
like from the English. Of course, the estates of the English aristocracy were
tended by a staff of gardeners. England also has a milder climate, and the
grass that looks so nice there doesn’t do as well in North America. In the
1930’s the USDA came up with a blend of imported grasses that would
tolerate our climate. Since these grasses are not native, they need help, and
that calls for fertilizers, pesticides and lots of extra water. Since normal
people can’t afford gardeners who trim by hand, that means lawn machines.
American industry to the rescue.


(mower starts up, fades under next sentence)


A quick Google tells me that today we have 40 million lawn mowers in use.
Each emits 11 times the pollution of a new car, and lawn mowers contribute
five percent of the nation’s air pollution. Plus more than 70 million pounds of
pesticides are used each year and over half of our residential water is used
for landscaping. Don’t you love those automatic sprinklers that come on in the
rain? Add to that all the time that people spend mowing and edging. Of
course the two billion dollar lawn care industry is thrilled about all this
enthusiasm, but I gotta ask, “Is it worth it?”


Call me old fashioned, but I actually prefer the looks of a meadow with mixed
wildflowers and grasses to the lawn that looks like a pool table. My own lawn
is somewhere between. It’s mowed, but it’s what you might call multicultural.


There are at least five different kinds of grass with different colors and
thicknesses, plus clover, dandelions, mushrooms, a few pinecones, and a
rabbit hole or two. There’s also some kind of nasty weed with thorns, but even
that has nice purple flowers if it gets big enough.


Clover, by the way, used to be added to grass seed because it adds nitrogen to
the soil. Now we just buy a bag of nitrogen fertilizer, so who needs clover?
And what’s wrong with
dandelions? You can eat them, some people even make wine out of them,
they have happy yellow flowers; yet to most people they indicate your yard is
out of control. So I’m down on my hands and knees pulling dandelions. I’m
not sure why, but I hope it keeps the neighbors happy.


One thing I won’t give in to, though, is the chemical spraying trucks, painted
green of course, that roll through the neighborhood.


I can only hold my breath. (sound of trucks and mowers) Try not to listen. And
wait for the evening. (evening insects)


(air conditioner starts up)


Although, with all these air conditioners, even the night’s not too quiet.


But that’s another story.

Carrying the River Within Us

We don’t have to travel far to experience nature. Many of us have special places that connect us to the natural world. Great Lakes Radio Consortium commentator Bob Hamma reflects on the lasting impact those places can have on us:

Transcript

We don’t have to travel far to experience nature. We all have special places that connect us to the natural world. Great Lakes Radio Consortium commentator Bob Hamma reflects on the lasting impact those places can have on us:


One day in early September, my son and I rented a canoe and took a trip down the St. Joseph River where it crosses from Indiana into Michigan. The cloudless sky was a rich, deep blue and the light breeze created just a soft ripple on the river’s surface. Young turtles sunning themselves on logs plopped in the water as we glided by. We spied an occasional blue heron perched on the bank and a few swans moving gracefully through a pool.


The river was surprisingly empty of human presence. There were a few boys fishing under a highway bridge and a single pontoon boat. But they did not rob us of the sense that the river was ours, that on this river so close to home, there was a quiet, peaceful world without the pressures and demands of our everyday life. I like to remember that day, not only for its quiet beauty, but to create a peaceful space within myself. I want to carry that day, that river, within me.


I close my eyes and I am there. The river becomes part of me and part of the bond between my son Peter and me. It flows through my mind, carving a path through my psyche, laying bare the texture of memory. I travel upstream and remember the joys and sorrows that have formed the course of my life. I am carried downstream as I recall the people, places, and things that I cherish, moving always toward the great sea to which every river flows.


As the river becomes a part of me, I sense my life as a whole rather than as scattered fragments. There is a peaceful center, which I need only take the time to connect with. I know that just like this river I come from somewhere and am going somewhere; that I am a part of something greater; that I belong to people and to places.


When you are bruised or troubled, go to that place where you connect deeply with nature. Go to that river, that woodland, that mountain. Let the river carry you, the forest shelter you, the mountain bear you up. Close your eyes and go to that place which is for you a source of life.

Reducing Road Noise

Efforts to reduce noise pollution are making progress in Indiana.
Last year, Purdue University opened the Institute for Safe, Quiet, and
Durable Highways. The Great Lakes Radio Consortium’s David
Naylor reports:


In the past, measuring road noise meant measuring the sound of a
car’s mechanical systems, primarily engine and muffler noise. Now,
with the development of more efficient engines, researchers have
identified the tires and road surface as the newest problem.


So, Purdue researchers are looking for the quietest combination of
tire treads and pavement. They say the most promising surface so far is
one developed in Europe: a thick layer of asphalt, with pits one and a
half to two inches deep.
It reduces road noise by about 50% and does well in the
freeze-and-thaw cycle. But the major problem is keeping oil and dirt
out of the deep pits.
Lab director Bob Bernhard hopes a double layer of pavement will
help.


“One which has the properties that they think are optimal for acoustics, and then put a second

layer below it, which has bigger spacing. In that way, they can flush the dirt and the things that

are plugging, out of the top layer, where the acoustics are affected, in the bottom layer, and

then flush it out.”


Research on the porous pavement continues in Europe and the U.S.
There are no plans yet for commercial production.
