Researchers affiliated with CalPoly University and the Max Planck Institute designed a “phantom sound” method to systematically explore the effects of
exposure to birdsong on the well being of hikers in a natural landscape. Guess what: just the sound of birds singing makes a significant difference!

The method used for this study echoes Jesse Barber’s brilliantly-conceived and widely-acclaimed “phantom road” research at the University of Idaho that showed the effects of highway noise on birds’ migratory and feeding habits.

Both of these research projects brilliantly demonstrate the importance of careful experimental design in doing noise-effects research. Congratulations to the participants in both projects! They will both advance the need for regaining control of the long-neglected issue of noise exposure.

Irish commuters to be serenaded by birdsong at train stations

The Irish Examiner reports that the Irish train system, Iarnród Éireann, will be playing birdsong at train stations between 8:00 a.m. and 9:00 a.m. until November 29. The birdsong  recordings were made in Dublin during the lockdown quiet, which allowed people to hear birds instead of vehicle and train noise.

The newspaper reports that “On Chorus is a public art project by sound artist Christopher Steenson which aims to highlight the dramatic reduction in noise pollution in Ireland during the first Covid-19 lockdown.“ Steenson’s art work asks listeners to reflect on the relative quiet during the lockdown, and also is a gesture of appreciation to essential workers, who in Ireland were the only ones permitted to travel during the lockdown.

The birdsongs will be played from 8:00 a.m. and 9:00 a.m. Irish time here for anyone who wants to listen. Irish Standard Time is Greenwich Mean Time 0. In the United States, Eastern Standard Time is GMT -5, Pacific Standard Time is GMT -8. A series of photographs taken by Steenson will also be available on the site.

What a wonderful idea: making art from the silver lining to the terror and tragedy of the COVID-19 pandemic, as Steenson does, reminding us of the beauty of nature amidst man’s horrors.

Are birds singing more loudly?

by Daniel Fink, MD, Chair, The Quiet Coalition

With markedly decreased road and aircraft traffic due to lockdowns imposed during the COVID epidemic, many observers have noted that they can hear birds, especially in cities. Some have also noted that the birds are singing more loudly. This report from radio station WAMU states that is not the case, however.

It turns out we just hear the birdsong better because they aren’t competing with traffic noise. As ornithologist Sue Ann Zollinger notes:

“Although our perception might be that they’re singing louder, it’s actually likely in places that are typically noisy that they’re singing more quietly than normal,” Zollinger said in an interview with Morning Edition. “But when the noise is gone, they’re probably singing quieter than they do normally.”

I am glad to be able to hear the birds, whether they are singing more loudly or not, and will miss their sweet songs when things eventually get back to a new normal.

Will the pandemic teach us to listen once again?

For an individual who has focused more on her auditory receptor than her visual receptor for the past forty years, I spent much of my time convincing others to pay as much attention to their sonic environment as they do their visual surroundings. I have urged people to recognize the dangers of loud sounds and noise to their hearing and their overall mental and physical health. Similarly, I write about the pleasures of the good sounds around us. The last page of my children’s book “Listen to the Raindrops” (illustrated by Steven Parton) reads:

Moms, dads, girls and boys join together to stop the noise, So that we can one and all, Forever hear the raindrops fall.

As the years passed, I have had more success with my efforts, but now with the coronavirus pandemic it appears that many people who paid less attention to their aural environment than their visual have now awakened to the stimuli that reach into their ears and then impact on their experiences. In “Hopeful birdsong, foreboding sirens: A pandemic in sound,” Leanne Italie writes:

The coronavirus has drastically transformed the world in sound. The routine cacophony of daily life has calmed, lending more weight to the noises left behind. And in those mundane sounds, now so unexpectedly bared, many have found comfort, hope and dread.

Italie goes on to explain how the sounds she is now tuned in to affect the listeners emotionally. Ambulance sirens break ones heart, but the balcony singing in Europe and the applause and whooping at 7 p.m. in New York, saying thank you to our medical care workers, is viewed as uniting people. The increased silence has made people more aware of the snippets of sound in the street when they venture out, Italie writes. She also writes about the visually impaired who depend on the sounds around them to navigate their streets. The article ends with a call to keep listening.

I strongly agree that we should keep listening as I have said for all these years. Become aware of the too loud health-damaging sounds, e.g. aircraft, rail and road noises and advocate to lessen them so that we can all appreciate the quiet that brings comfort as well as allowing us to forever hear the raindrops fall.

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.

This is fascinating:

Plants Have an “Ear” for Music. Matthew Sedacca, Nautilus, writes about Dan Carlson, Sr., who, after his experience in the Korean demilitarized zone in the 1960s, dedicated himself to “increase plant growth and help reduce, or even eliminate, world hunger.”  Carlson studied at the University of Minnesota, trying to learn everything he could about how plants grow.  What he discovered was interesting:

Years later, Carlson believed he found part of his answer. He maintained that “green music”—sounds akin to, or recorded from, those found in nature, like birds singing or crickets stridulating—possesses frequencies that boost plant growth and yield rates. He claimed that when exposed to synthesized birdsong, a plant’s stomata—the mouth-like pores on the underside of leaves that absorb water and nutrients and expel oxygen—widen. Before he died in 2012, he listed growing a Purple Passion (Gynura aurantiaca)—a houseplant that usually grows up to a foot—1,300 feet high to the sound of green music as one of his lifetime achievements. It earned him a Guinness World Record.

Yes, it sounds kind of nutty, and some people in the past relied on pseudoscience, but today “plant bioacoustics is a growing field of interest in science.”  In fact, in “a recent study published in Scientific Reports, a team of researchers from Yeungnam University in Gyeongsan, South Korea, found, just as Carlson did over 30 years ago, that “green music” can cause plants to undergo biological transformations.”
