Will orcas sink whale-watching boats because of noise pollution?

            Even if they haven't read the novel, most everyone knows the ending of Moby-Dick: the white whale sinks Captain Ahab's whaling boat, the Pequod, and all perish save Ishmael, who survives to tell the tale. So it may not have been entirely surprising to hear recent news reports of orcas (killer whales) attacking and seriously damaging fishing boats--already twelve boats this year. As it happens orcas have been well studied by not only by biologists but also by ecomusicologists interested in the sounds they make. Orcas find their food by echolocation; that is, by sending out sound signals and listening for the echoes to located prey. Orcas, like other whales, also communicate with one another via sound.

            Ecomusicologist Mark Pedelty made a documentary film, Sentinels of Silence, about how the propeller noise from powerful whale watching boats in the Salish Sea (the waters off the northwest coast of the United States and the southeast coast of Canada) upsets the orcas that live there, making it impossible for them to locate their food or one another. Whale-watching is a major tourist business in the area, but orcas are an already endangered species. This intrusion into the ocean sound commons undoubtedly makes it more difficult for orcas to survive. Animal rights activists fought the whale-watching industry and, with the help of Pedelty's film, were able to convince the government to regulate the noise pollution from the whale boats.

            The dozen orca attacks this year all occurred off the coasts of Spain and Portugal. Some scientists hypothesize that these orcas may be attacking those fishing boats for vengeance: either because the boats are interfering with the orcas' food supply, because the orcas get entangled in the fishing gear, or even because one of them was struck by a fishing boat. None of the scientists mentioned the possibility that propeller noise was a reason for the orca attacks. The scientists attribute agency to the orcas and have observed a female named White Gladis "teaching" the other orcas to attack the boats. This behavior hasn't yet been observed in the Salish Sea, but it's not beyond possibility.

BLAST: a citizen initiative to stop noise pollution

"Ban Leafblowers And Save Our Town"

How can noisy machines help clean the world, when noise itself is a form of filth?--Ashleigh Brilliant, BLAST "leader by default"

On the evening of the Santa Barbara municipal elections, self-described BLAST "leader by default"Ashleigh Brilliant paraded about the election station. Brilliant was armed with a push broom and a victory statement reinforcing Santa Barbara's disgust for "the noise, dirt, and pollution of a device which should never have been permitted in our city in the first place." Finally, three tries at a referendum and fifteen years of work to ban leafblowers won out for Brilliant and his coalition. According to Brilliant, leafblowers are "...the least justifiable and most obnoxious technological monstrosity I can think of. And it's not really a leaf blower, it's a dirt blower. I mean, how many fallen leaves do we have to deal with?"

"A ban is a very easy law to understand," he says. "You just can't do it at all with that machine." Before the ban was in effect, Brilliant resorted to self-help measures, once physically removing the leafblower from a nearby gardener's back. One year later, Brilliant grabbed the leafblower from the gardener and repeatedly smashed it to the ground, but only after begging the gardener on bended knee to stop using the blower.
Leaf blower decibel count. LOUD!
It is no surprise that forty cities in California alone, and over three hundred cities nationwide, have banned leafblowers. There are as many ways to describe the noise that leafblowers emit as there are people who are disturbed by them. From fifty feet, gas-powered leafblowers create up to 70 decibels of noise. Most would identify with the high grinding whine we know so well, not to mention other environmental hazards created by leafblowers such as exhaust fumes and swirling clouds of airborne debris.

Leafblowers grew in popularity since the 1970's. Santa Barbara has "regulated" leafblowers for the past ten years, but the city still suffered with lack of enforcement and regulations that were not restricitve enough. At one time the city tightened existing regulations, but to no avail. BLAST was formed in February 1997, and fifty unpaid volunteers collected more than nine thousand signatures asking to put the issue on the ballot in November of 1997. In early November, 54.5 percent of voters elected to place a total ban on all leafblowers within the Santa Barbara city limits.

Some of the resources that BLAST used to quiet the neighborhoods include an official "ballot argument" stating BLAST's position, bumper sticker, an "initiative measure" containing the ordinance purpose, summary and language; and the "notice of intent" to circulate the initiative petition, containing a statement of the reasons for the ban. To view these items, click on the links from each phrase.

BLAST's pre-election opposition came in the form of the City Parks and Recreation Department, professional gardeners and landscapers, garden supply shops, and one of the nation's leading leafblower manufacturers. They formed a coalition to oppose the ban called CORE: Citizens Opposed To Radical Enactments. These parties claim that irresponsible leafblower users are the problem, and recent market innovations include leafblowers that are half as loud as the former machines. They raised more than $10,000 to further their opposition, while BLAST's campaign was so low-budget that they did not reach the threshold requiring that they report their spending. CORE members claimed that owners of commercial and office buildings will be hit hardest, where leafblowers are used on a grand scale to clean parking lots and walkways.

Money is also a consideration, with leafblower advocates claiming that leafblowers save a great deal of time and labor and contribute to the appearance of the city. Brilliant counters this by stating that if all gardeners have to compete under the same restrictive regulations, nobody will have a competitive advantage. Also, "cleanliness" has gotten out of control-- what about the need for a natural setting? Brilliant believes that it is not a matter of right and wrong: "Our opponents are just as interested in a beautiful city as we are. It's just that they have a more narrow vision of that beauty."

The ban takes effect in February of 1998, although the City Parks and Recreation Department stopped using the machines shortly after the election, beginning a process of major change for the City of Santa Barbara.

Noise Pollution and the EPA: Celebrating Earth Day



Planet Earth: the "blue marble" photo.
Today is the 50th anniversary of the first Earth Day and Earth Week. The NASA “blue marble” photograph of Earth, taken from space, was published two years later. The photograph gave us a new perspective. It showed once and for all how all Earth’s creatures were bound together on a journey through the solar system, bounded as we were by Earth’s fragile biosphere.

Environmentalism in 1970 was all about curbing pollution of the commons: air, water, soil. The villains included atomic waste, pesticides, toxic metals, automobile exhaust, sewage, factory smokestacks, plastics, and so on. We were intent on making Earth a healthier place for humans primarily, but also for other species, especially endangered species. In response President Nixon set up an environmental council and, following their recommendations, asked Congress to set up a federal agency to monitor the environment, to organize and coordinate federal programs and to assist states, and to issue guidelines and regulations, all to reduce pollution. Seven months after the first Earth Day, the Environmental Protection Agency was established.

The EPA soon became concerned with noise pollution as well. Although local governments had long enacted noise ordinances, the 1972 Noise Control Act gave the EPA authority to regulate noise associated with construction and transportation. The EPA began to work with aircraft manufacturers, airlines, and airports to reduce engine noise and re-route takeoffs and landings to avoid the most heavily populated areas. In 1979 the EPA established a new noise label program to give home products like vacuum cleaners, shop tools and chainsaws decibel ratings, indicating those to which prolonged exposure was unhealthy. I recall when I bought my first chainsaw in the early 1980s that I also purchased noise-canceling headphones. Coordinating efforts through the EPA Office of Noise Abatement and Control, the EPA also got Congress to establish the 1978 Quiet Communities Act. 

One of the most important things the EPA did in its early days was to encourage scientific research on the psychological and physiological effects of noise pollution. In 1978 the Noise Abatement Office published a helpful pamphlet, Noise: A Health Problem. It summarized research on the effects of noise on hearing loss, heart disease, special effects on children and the unborn, intrusion at home and work, sleep disruption, and mental and social well-being. Among its conclusions were the following:

*Noise can cause permanent hearing damage, and people with hearing loss suffer discomfort and social isolation.

*Noise produces stress that contributes to heart disease and other illnesses.

*The fetus is not fully protected from noise. Noise may threaten fetal development.

*Noise may hinder language development in children.

*Noise hampers work efficiency.

*When sleep is disturbed by noise, work efficiency, health and well-being may suffer.

*Noise can cause extremes of emotion and behavior.

*Noise can obscure warning signals, causing accidents to occur.


In 1981 the Noise Abatement Office published a lengthy and still very useful Noise Effects Handbook: A Desk Reference to Health and Welfare Effects of Noise. Whereas Noise: A Health Problem was aimed at a popular audience, the Noise Effects Handbook included data from scientific research and made a convincing case for the harmful physiological and psychological impacts of noise pollution.

Although funding for the Noise Abatement Office was stopped by the Reagan Administration in 1982, as the federal government gave over noise abatement responsibilities to state and local governments, the Noise Control and Quiet Communities Acts were never rescinded. They remain in effect today, although they are unfunded and unenforced. Meanwhile, a great many state and local citizens groups and NGOs organized in opposition to noise pollution. Among them were HORN (Halt Outrageous Railroad Noise), and BLAST (Ban Leafblowers and Save our Town), a Santa Barbara, CA organization. The next blog entry shows how BLAST became a model for citizen activism through the ballot with petitions, bumper stickers, and other measures. When a majority of the citizens of Santa Barbara voted in favor of the ban in the November, 1997 election, it took effect the following February.

Natural Sounds in the National Parks

Scott McFarland demos recorder in the Park
    In an earlier blog entry I mentioned a collaboration with Scott McFarland, biologist at the Great Smoky National Park, who is in charge of their Natural Sounds project. Just yesterday, a long “cover story” by Erin Young was published in the Knoxville Mercury, featuring Scott’s work there. This summer, he has been setting out sound-monitoring digital recorders in several Park locations that will document the soundscapes continuously for thirty-day periods (after which time the batteries must be changed). The recordings will not only measure human-caused (anthropogenic) sounds, such as those made by vehicles, construction, airplane flyovers, and so on, but also those geophonic sounds made by wind and water, and the biophonic sounds made by animals. These recordings will be compared with some made 10 years ago in the same locations, to determine the changing sounds and measure the various noise levels, all with a view to minimizing noise pollution to enhance the visitor experience as well as the acoustic habitat for the plants and animals.
    I was on the phone with Scott a few days ago to obtain his permission for a different recording—the one made of our symposium on music, sound, and environment last April—to be placed in ETSU’s Sherrod Library, where it will be available for educational purposes and fair use. At that symposium, Scott and I, along with ecomusicologists Aaron Allen, Denise Von Glahn, Mark Pedelty, and Chad Hamill, spent an afternoon and evening in a public conversation which ranged widely over that theme. We were especially caught up with the alterations to the soundscape being caused by climate change, and other anthropomorphic changes to the sonic habitat. The symposium was well-attended—seats had to be added for an overflow crowd—with faculty and graduate students traveling from universities out of state, as well as in-state, to hear and then participate in the question-answer period at the end of each of the two sessions.
    This year marks the hundredth-year anniversary of the US National Parks. With the attendant publicity, it is good to have some of it directed to the National Park Service's (NPS) Natural Sounds conservation project. And it is good to have people like Scott McFarland working on it. He was most generous with his time, visiting ETSU twice—once for this symposium, and another time for a presentation in a seminar I was teaching on ethnomusicology and the soundscape ecology of Appalachia—and hosting me when I visited the Great Smoky National Park. On my visits I noticed a few signs on the highway that read “Quiet Walkway,” pointing to trails leading into the woods. I decided to try one and learn how quiet it was. About a mile in, I found a few small streams, the water coursing over the rocks, making the usual pleasant geophony, while mockingbirds sang occasionally. Yet I could still hear the vehicular traffic and construction noise, and I’m sure that the mockingbirds could hear it as well. I’ve mentioned in earlier blog entries the acoustic niche hypothesis, that animal species communicate in particular sound niches so as to minimize interference from other sounds. As they move to different habitats and experience different sounds—including anthropogenic ones—they must adjust their niches to the changes in the soundscape. Experiments with birds and their songs appear to confirm this hypothesis. Evidently they can learn to do this within a generation or two—it isn’t a matter of evolution by natural selection.
    Scott intends to head to coastal Maine with his fiancĂ©e in late September, and we hope to meet up near Acadia National Park, where he will spend some time. Perhaps a NPS Natural Sounds program could function there, as well. Acadia is well known for its partnerships with natural scientists who have been studying the changing animal and plant communities there; could sounds be next?

A Human-Centered Sound Commons?

    In my previous blog entry I suggested that it is helpful to think of the acoustic environment as a sound commons. The usual example of a commons is land that members of an agricultural community use for grazing livestock. New England towns traditionally set aside a plot of land that was called the “town common”; these still exist in some towns, such as Amherst, Massachusetts, very close to my alma mater, Amherst College. Of course, the citizens of Amherst don’t graze their sheep and cattle on the town common anymore; it’s a park, and it’s used for public events. English peasants farmed on commons land until villages were transformed by enclosures (private property), a gradual process that took place mainly in the 1700s. In highland parts of Europe, and also in North America, livestock were let more or less loose to graze and feed on mountain land in season, sometimes with shepherds, sometimes without. Deep water ocean (for fishing) is another example of a commons. In a commons, then, members of a group share a particular resource, and the people who use it assert that they have rights, or entitlements, to do so.
   
     I raised the idea of a sound commons in the context of an acoustic disturbance, the sounds of helicopters flying, which confuse and upset caribou and cause the herd to change its migration pattern, which in turn impacts Innu people of northern Canada, whose lives traditionally are bound up with hunting caribou. A question immediately arises: is the acoustic environment a commons? And if so, which group am I talking about here in regard to a sound commons: the Innu or the caribou, or both? I think we can assume that the Innu have moral, if not legal, rights in this case, their right as a people to hunt caribou, which is compromised by the helicopter noises that take place in a sound commons shared by all human beings. Of course, the corporations who fly the helicopters and build the roads that make the noise assert opposing rights, to find and extract minerals from the land: that the benefit to humanity realized from mining the minerals outweighs the harm done to the Innu. But does it make sense to say that caribou have any rights in the matter? On what grounds could animals (including non-humans) have rights to a particular kind of acoustic environment or sound-world?
    The concept of commons has been around for a long time in Europe, going back at least to Roman law, which recognized as res communes those things that were incapable of being possessed by individuals and thus were commonly available to all. The usual examples Roman law gave for res communes were water and the atmosphere (the air mantle). The history of the commons has been one of enclosure, or propertization of the commons, whether public property or private. The enclosure of agricultural land in England (and Europe) is the usual example, but in modern history water and air resources have come to be regarded as public property, to be regulated by governing bodies; and some individuals even have claimed water and air rights as private property.
    The Internet has gotten people talking about commons once again: an information commons, with free Internet access (a digital information commons), is a right that is asserted by information managers (librarians) and readers, while there is pushback from authors and publishers. In the same way, digital file sharing (recordings, movies) has resulted in claims (particularly from youth culture) of a media commons, with pushback from artists and the recording industry. In an important book, Common As Air, Lewis Hyde has placed the debate in a larger context, arguing on behalf of a cultural commons of art and ideas, shared by all members of a society. Important ethical questions arise, such as how to mediate between free access to ideas, on one hand, and to protect the rights to their own ideas that individuals, particularly creative artists, assert, called intellectual property rights, on the other.
     One legal solution is the so-called "fair use" doctrine, in which small portions but not entire works are freely accessible. Anyone who has read portions of a copyrighted book on Google Books knows how this compromise works. Hyde supports the original American copyright law, which offers copyright protection for a once-renewable period of 26 years, after which time the property passes into the public domain where it may be used freely by all. These are very lively issues in legal circles today, particularly as global corporations (as “persons”) with enormous financial resources assert rights to movies, recordings, books, and so forth. But although there are many interesting questions involved, such as whether music, for example, ought even to be regarded as property—Thoreau would have thought it preposterous to do so—here, this debate serves mainly as background, at least for the time being.
    The concept of a sound commons is not original with me. Although the idea may be older than the late twentieth century, at that time environmentalists concerned with noise pollution asserted that people have the right to silence, to be free from assaults with noise; and at least two based this assertion on the principle of a sound commons. In 1993 Ursula Franklin gave a lecture at the first international conference on acoustic ecology, in which she said: “I want to come back to the definition of silence and introduce the notion of the commons because the soundscape essentially doesn’t belong to anyone in particular. . . . The notion of the commons is deeply embedded in our social mind as something that all share. . . . Because of the ephemeral nature of sound, silence was not considered part of the commons in the past. Today the technology to preserve and multiply sound and separate it from its source [i.e., what Murray Schafer termed schizophonia] has resulted in our sudden awareness that silence, too, is common good.” (1)
    In a similar vein, in 2000 the acoustic ecologist Henrik Karlsson wrote that “. . . a healthy, unspoiled acoustic environment [must] become something of a common right—a public domain—to which all citizens should have free access, no matter where they live. The acoustic environment will then become something which nobody can sabotage for others or privatise for personal gain. The focus of attention will then be on the individual citizen and his [sic] needs, not on product development or other economic interests, whether individual or transnational. An anthropocentric model of this kind, I am convinced, is the only feasible way of regarding, restoring and preserving the acoustic environment.” (2)
    Both Frankin and Karlsson conceive of a sound commons as “anthropocentric” (human-centered) and would have no argument with Innu asserting rights over their acoustic environment. They do not theorize the sound commons, as I am starting to do here; they simply propose it to be true on the grounds that the acoustic environment belongs to and is shared by all (humans). And although the acoustic ecology movement calls attention to the harm Navy sonar does to whales and dolphins, their main issue is noise pollution and its impact on human beings. The sounds of the natural world are “unspoiled” and must be respected, but their activism is aimed chiefly at the impact of noise pollution on people. In the case of the helicopters, the caribou, and the Innu, the acoustic ecology group would primarily be concerned, as the Living on Earth reporter was, with the Innu, not the caribou. It would be a more radical step to propose that there exists a sound commons for all creatures, but that is what I am suggesting here. In a future blog entry I will argue that the concept of commons leads us to conclude that all creatures, not just humans, have the right to communicate in their acoustic spaces (or niches). An anthropocentric sound commons is too narrow in scope.

The Sound Commons

Caribou
A new sound has come to the George River in Labrador, northern Canada, where the Innu traditionally relied on hunting caribou for food and clothing. It is the sound of helicopters flying through the air bringing in engineers and prospectors exploring the area for minerals. According to George Rich, an Innu elder, “the sound of the choppers really is a devastating sound because they [the caribou] don’t know where to look, all these choppers are going flying all over the place.” The result is a declining herd and a changed migration route, away from the traditional hunting grounds. “One of the mineral exploration companies is trying to build a road right in the heart of our territory. Right in the heart of [caribou] calving grounds,” Rich said.(1)   
    One thing leads to another as an intrusive new sound threatens what is left of a way of life. Besides their importance for diet and clothing, caribou “is our identity,” Rich said when interviewed recently for a radio broadcast. “It’s our culture, it’s our way of life. It’s also a part of the big spiritual awareness of what’s going on in the animal world. And without the caribou we don’t think the Innu will be able to survive.” The Innu are so isolated in their northern fastness that without as many caribou they are getting food shipped to them in the summer when the waters are open, or flown in to them in winter. “And then that’s created a lot of problems in diet and eating junk food. . . . A diabetes epidemic is one of the things that we are facing right now,” Rich concluded.
Traditional Innu camp
     There are 850 Innu living in a village 150 miles north of Goosebay, Labrador. They were not always villagers. Until about fifty years ago Innu were nomads, living in camps and following the migration routes of the caribou. The caribou herd, then estimated to have numbered as many as 900,000, has declined to less than 28,000. Of course, the sound of helicopters and road construction isn’t the only thing affecting the caribou. Global warming is doing its part. Caribou bear their calves in cool weather, and they forage for food beneath the powdery tundra snow. The warmer weather brings black flies, makes it more difficult to calve, and covers the ground with rain that freezes to ice and prevents browsing. And the Innu way of life underwent profound change when they were forced to settle in villages. But they still hunt caribou, though now subject to Canadian law which forbids them to hunt in certain places and at certain times. When they violate the law--as they sometimes do--they are subject to arrest.
    But for George Rich, it was the noise pollution from the choppers that most clearly--and most recently--affected the herd. We are not used to thinking in terms of sound-worlds when we measure the environmental effects of development. We usually limit our gaze to the visible landscape: forests cleared for timber use, farmland covered with factories and shopping centers. Sound? It seems so ephemeral. The warnings coming from acoustic ecologists about noise pollution in urban environments seem trivial by comparison. But are they? It isn’t just that sirens and jackhammers are deafening; they cause anxiety and confusion in humans as they do in caribou.
    Not unexpectedly, the Innu have music about the caribou, hunting songs that were passed from one generation to the next. What would a hunting song be about? The strength and prowess of the hunter? A boast or a threat to the prey? A triumphant enactment of the kill? None of the above. Instead, they establish relationships with the caribou. George Rich translated one of them: “You are so far away, I cannot reach you. I’ll catch up with you and call my friends.” This is how music evokes, and shapes, the “big spiritual awareness of what’s going on in the animal world,” as Rich put it. The music of the Innu is not only a critical part of the Innu sound-world, but it embodies Innu worldview.
    “I do hope the caribou come back soon,” the radio host said, somewhat lamely, in ending the interview with George Rich. Rich could not help but agree. They were hoping for resiliency. Beyond hope, though, we might try management: get those helicopters out of there, stop building the road, stop exploring for minerals, and understand that the effects of climate change will be felt not only by vulnerable peoples in remote areas but by every creature everywhere on the planet. Music, sound, nature, culture: again, it’s all connected. A sound-world is not simply an acoustic environment, a container for music and noise. Incidents such as this one with the caribou among the Innu show how a sound-world is a common-wealth, a commons shared by all. Managing the sound commons starts with understanding its nature and significance.
