Noise and wildlife

Noise pollution impacts many species

by Daniel Fink, MD, Chair, The Quiet Coalition

This article in Smithsonian Magazine discusses a meta-analysis in Biology Letters documenting the adverse effects of noise pollution on animals, ranging in size from small insects to giant marine mammals.

We have recently redefined noise as unwanted and/or harmful sound. Nature is quiet, not noisy. I documented the evidence-based noise levels affecting human health and function, starting with sleep disruption at sound pressure levels as low as 30-35 A-weighted decibels*, in an recent article in Acoustics Today. I don’t think the data exist to write a similar article about specific noise levels affecting non-human animal health and function, but the definition of noise as unwanted and/or harmful sound was meant to include animals, too.

Noise pollution is ubiquitous. A quieter world will be better for most living things, including all animals and plants that depend on animals for functions like pollination and seed dissemination.

*A-weighting adjusts sound measurements to reflect the frequencies heard in human speech.

UK supermarkets leading the way on noisy fireworks

Three UK supermarket chains are vowing to only sell low-noise fireworks after Sainsbury, one of the UK’s biggest chains, has banned sales of fireworks outright. This follows a petition to Parliament seeking to ban fireworks entirely as “a nuisance to the public.” According to The Mirror, over 300,000 signed the petition, which states that the noise from fireworks scares children, animals, and “people with a phobia.”

The Brits do love their dogs, so no surprise many cite their pup’s aversion to firework noise as a reason for the ban. In fact, The Mirror notes that “the Scottish Government earlier this year found that 94% of 16,000 respondents wanted to see tighter controls on the sale of fireworks.”

Hear, hear. But why stop at tighter controls, when they should be replaced entirely. As we’ve posted before, fireworks are a complete environmental hazard. Enough!

The loudest bird in the world

This article in The New York Times discusses a species of bellbird that is the loudest bird in the world. How loud? The white bellbird makes noise at 125 decibels.

Hear for youself (reduce the volume or remove your headphones):

I’m glad it lives only in the Amazon, and not near me.

Want to adopt a pup but don’t want your neighbors to hate you?

Yahoo Lifestyle reports on the 20 breeds of dogs you should consider if you want to adopt a dog, but can’t deal with the noise.

We couldn’t help but notice that one of the suggested breeds is Pekinese, and we recalled–not with fondness–a former neighbor’s Pekinese that surely was the exception. So take the list with a grain of salt, but know that there are options for sound sensitive–and considerate–dog owners.

Exciting research on the biological effects of noise on birds

by David M. Sykes, Vice Chair, The Quiet Coalition

Recently we wrote about real “angry birds”—-research on birds showing that exposure to noise makes them hostile. That called to my mind some very exciting research by Jesse Barber, PhD, at Boise State University that was highlighted at a Public Outreach Workshop in Denver, Colorado, several years ago and has the enthusiastic support of scientists at the National Park Service.

Dr. Barber’s innovative research design got a lot of attention. He has written extensively about the effects of traffic noise on birds and how noise is an invisible source of habitat degradation

Dr. Barber is one of the emerging heroes in research on the biological effects of noise. He recently gave a TEDx talk that provides an overview of his perspective. Watch for more exciting work from his lab in Idaho.

David Sykes chairs several professional organizations in acoustical science: QCI Healthcare Acoustics Project, ANSI Committee S12-WG44, the Rothschild Foundation Task Force on Acoustics, and the FGI Acoustics Committee. He is lead author of “Sound & Vibration 2.0” (Springer, 2012), a contributor to the NAE’s “Technology for a Quieter America” and the GSA’s “Sound Matters,” and co-founded the Laboratory for Advanced Research in Acoustics at Rensselaer Polytech. A graduate of UC-Berkeley with advanced degrees from Cornell, he is a frequent organizer of professional conferences in the U.S., Europe, Asia and the Middle East.

Country File magazine reports on recent research by Manchester Metropolitan University with Manchester Airport that found birds living near airports “are exposed to extreme noise levels from jet engines” which interferes with communication during breeding season. Interestingly, not only is communication affected, but the researchers found that common chiffchaffs living near loud aircraft were five times more likely to attack a speaker playing bird song than chiffchaffs who lived further away from airports. That is, the noise made the birds more aggressive.

We were not entirely surprised that noise would cause aggression in animals, as some studies show that noise causes or exacerbates aggression among humans.

Just another reason to lower the volume, everywhere.

 

 

It’s that time of the year: How to help your pooch on the 4th

Every year around the 4th of July we see a couple of articles on how to help your pet deal with the trauma they suffer during fireworks season. This year the advice is courtesy of the Carroll Count Times, where correspondent Iris Katz dispenses the usual nuggets of useful information:

Owners are advised to slowly inhale and exhale when fireworks and thunder start, play calming music, keep high value treats or toys on within reach to give the dog when thunder starts or a firework goes off and to keep tossing treats and toys. Food puzzle toys, like goody-stuffed Kongs or food dispensing toys, may be pleasant distractions for sound-sensitive dogs.

And every year we report on how fireworks drive dogs, in particular, mad. There’s even a medicine to treat doggy anxiety.

But one thing we in the U.S. don’t often hear is that loud fireworks are unnecessary. Rather, the sound is designed into fireworks displays, and quiet fireworks displays are possible. In fact, some thoughtful towns and cities in Europe and the Galapagos are starting to require quiet fireworks displays to protect pets and wildlife.

Isn’t it time we start doing the same here?

Why noise pollution is more dangerous than we think

The May 13, 2019 issue of The New Yorker magazine has a wonderful article about noise by staff writer David Owen. Complementing the article is this 8-minute YouTube video in which Mr. Owen talks about what he learned writing the article:

It’s well worth spending the time to watch.

Music festival noise stresses out research fish

This report in the Miami Herald discusses how noise from the Ultra Music Festival “stressed out” fish kept at the University of Miami for research purposes. Toadfish, a common species in Miami’s Biscayne Bay, were more stressed than if they had heard the clicking sounds made by dolphins, which are a major predator for toadfish.

“So what we’re talking about here and what our data show presently is that Ultra was causing a short-term acute stress on our fish,” said Danielle McDonald, a University of Miami associate professor. “We don’t know and we cannot conclude whether this stress would have persisted over time,” she added.

I’m pretty sure the stress would have persisted.  Animals evolved in quiet, with sound detection being an important method of finding food for predator species, or avoiding being eaten for prey species.

In humans, noise exposure causes involuntary physiological stress responses, including increases in heart rate, blood pressure, stress hormone levels, and vascular inflammation

The one question I haven’t seen answered is whether voluntary noise exposure causes the same physiological stress responses as involuntary noise exposure. The fish obviously didn’t want to attend the rock concert, but the lab facility in which they lived was close enough to the music festival that they had to hear the music. Did the same changes occur in those who paid their hard-earned money to attend the festival?

If anyone has seen a research study answering this question, please let us know.
