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.

Scientists say the oceans are
getting noisier. The racket threatens
whales and other marine mammals that
communicate through sound. Nancy
Greenleese reports:


The oceans are already noisy from military sonars and oil and gas exploration. Scientists say it could get worse. Some of the greenhouse gas, carbon dioxide, is getting soaked up by the oceans and seas. The carbon dioxide makes the water more acidic. Sound travels through that acidic water more easily. A UN climate change panel recently issued a report raising concerns about the chemistry change. Mark Simmonds of the Whale and Dolphin Conversation Society says already there’s an “acoustic fog” in the world’s waters.

“The ambient noise levels in the oceans because of pH are likely to rise. This is a very unexpected finding. They’re anticipating that marine mammals will have further problems communicating.”

The noise confuses marine mammals. So, they’re beaching themselves and running into ships more often.

Environmentalists have wanted to
“Save the Whales” for decades. But experts
say that can’t happen until the people
realize whales don’t know if they’re in
American waters, Mexican waters or Japanese
waters. Nancy Greenleese reports whales
cannot be saved until all countries protect
them:

Whales travel off many countries’ coasts and different countries have different laws
about protecting the animals. Chris Butler Stroud is with the Whale and Dolphin
Conservation Society. He told a United Nation’s conference for the Convention on
Migratory Species that international cooperation is key.

“When countries try to take political action to conserve an animal, they often think of
their own borders. Not remembering that animals are able to move beyond those because
they don’t see the lines in the sand or lines in the water.”

(sound of Gray Whales splashing)

Gray whales swarm around fishing boats off Mexico’s Baja California peninsula.
They’ve traveled -without passports – from the Bering Strait in Russia, into U.S. waters,
through Canada, and back into the U.S. before arriving in Mexico. Here they’re
breeding, and providing a water show to rival Sea World for ecotourists.

“Oh…it’s the baby. Right there! Right next to us. And here comes mom! (Splash) Hey,
wow, right at us.”

There’s an international agreement that bans commercial hunting for gray whales. And
the whales draw tourists. That’s pretty important for a poor country such as Mexico.

The whales are safe here, but not everywhere.

And everywhere the whales travel and threat looms: climate change. Many whale species
migrate to the poles where the ice is disappearing. The World Wildlife Fund predicts
30% of the ice will melt away in the next 30 years unless action is taken.

Wendy Elliot says that means the whales will have to travel even farther to get to the ice
and the food they find there.

“So they’re already hungry, tired, they’ve traveled a long, long way and now they are
going to have 500 km extra to go. So how these species are going to adapt is very
unclear and it’s very concerning.”

Another worry is the growing acidity of sea water. Greenhouse gases from burning fossil
fuels mix with the water and make carbonic acid in the ocean. Monterey Bay Aquarium
Research Institute chemists have determined that the altered chemistry will increase the
distances that underwater sounds travel. That disturbs the communications of marine
mammals. The oceans and seas are becoming a headbangers’ ball from rumbling ships,
air guns used for oil and gas exploration and military sonars.

Nicolas Entrup, managing director for the Whale and Dolphin Conservation Society,
lobbied at the UN meeting for an international resolution on marine noise pollution.

“Look, we stressed to the governments that underwater noise is a key threat to whales and
dolphins in the ocean. These animals are acoustic animals.”

The Whale and Dolphin Conservation society says research shows loud underwater
noises causes some whales to beach themselves.

At the UN conference, nations passed watered-down resolution to reduce ship sounds.
They did nothing about the noises made by oil and gas industry and the military. Entrup
is furious.

What we’ve passed is absolutely not enough. And I have to say it’s giving in to the
interests of the military and the industries in that occasion. That’s really bad.”

Officials admit that industrial noise can be reduced but the military, that’s another matter.

The 85 governments at the U.N. conference did agree to provide addition protection for
some small whales. But putting any initiatives into effect will be difficult. The global
financial crisis has drastically limited countries’ contributions to field research on whales
and other migratory species. Entrup with the Whale and Dolphin Conservation Society
says the nations of the world cannot ignore the problems.

“If you care, then start now and do not wait until it’s too late. That’s expensive, that’s
irrational, that’s stupid.”

Wildlife groups say rich countries have to reach across borders and give a hand to poorer
countries if we’re going to save the whales.

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.
