How human-made noise affects animals

As I have written in previous posts, human-made noises have not only adversely affected the health and well being of people, but these noises also affect the well being of many species with whom we share this planet. Human-made noise forces the increased volume of urban bird calls, resulting in stress to some species, and deep-sea mining interests may have disrupted the lives of sea creatures for many years to come.

In her article for Psychology Today, Mary Bates informs us that noise pollution may hamper the communication of animals, “from insects to frogs to birds,” and this may have “potential consequences for mate attraction, territory defense and parent-offspring communication.” In support, she cites a new paper that reported the findings of a large number of studies that examined the impact of “anthropogenic noise,” or noise pollution, on animal communication. These studies found that animals had to make adjustments as a result of noise intrusions, and such adjustments could intrude on their existence. For example, when females had to call louder to attract males, these louder calls also attracted more predators, endangering the very lives of these animals.

The authors of the paper, Hansjoerg Kunc, Queen’s University Belfast, and his colleague Rouven Schmidt, conclude that it is essential for us to track noise pollution because the knowledge gained in such tracking will “ultimately determine the health of both ecosystems and organisms, including humans.” By including humans in this warning, they are cautioning us to protect our natural soundscapes not only to protect other species but ourselves as well.

Dr. Arline Bronzaft is a researcher, writer, and consultant on the adverse effects of noise on mental and physical health. She is co-author of “Why Noise Matters,” author of “Listen to the Raindrops” (children’s book illustrated by Steven Parton), and has written extensively about noise in books, encyclopedias, academic journals, and the popular press.  In addition, she is a Professor Emerita of the City University of New York and Board member of GrowNYC.

The Greatest Threat to Our National Parks?

It Might Be Noise Pollution.  Max Ufberg, writing for Outside, introduces us to Davyd Betchkal, the National Park Service’s soundscape specialist in Alaska, who studies the parks’ natural acoustic environment to determine “the ecological impacts of human-made noise.”  In doocumenting all 54 million acres of Alaska’s parks, Betchkal stated that two things are clear:

[S]ound is crucial to the health of plants and wildlife and everything from airplanes cruising overhead to the roaring of snowmobiles on the ground or the muffled ring of an iPhone in a jacket pocket affects—and often disrupts—the ambiance of our most precious natural areas.

Ufberg adds:

To be clear, in the context of natural places, birdsong isn’t noise; the buzz of an airplane is. Sound, by contrast, is a protected resource under the Park Service’s foundational Organic Act of 1916 as part of the profile of a natural environment. According to an estimate by Park Service senior scientist Kurt Fristrup, a national park goer hears human-created noise, much of it aviation-related, during about 25 percent of his or her visit.

“Noise is just as ubiquitous and broad in its impacts on the continent as air pollution,” Fristrup says.

Ufberg points outs that noise is linked to cardiovascular disease and elevated blood pressure, among other ills, noting that the Environmental Protection Agency classified noise as a pollutant since 1970.  “While [noise] poses a greater risk in cities,” writes Ufberg, “it’s increasingly become an issue in nature, too.”
