Teach for America is an organization that attempts to address the inequities in our educational system by providing a select group of outstanding scholars the opportunity to teach for at least two years in a low income school. TFA believes that teaching in these low-income schools will instill a lifetime commitment in these scholars to advocate for an excellent education for all children regardless of economic status.

Familiar with TFA’s goals, I was delighted to be asked by Holly Lebowitz Rossi, a freelance writer, to assist her with an article she was writing for the organization that focused on the importance of the soundness of school facilities, especially in low-income communities, on the education that took place within them. She knew that one of the problems in our school buildings is that too many of them lack the quiet that is most conducive to learning. Loud sounds may exist within the school buildings themselves because of faulty construction or may come from outside sources, especially when windows are opened, e.g. nearby traffic, construction, etc. She was familiar with my research and writings on the impact of noise on classroom learning and that is why she asked for my input.

Rossi’s article quotes Janelle Dempsey, a civil rights attorney, who says that by having young people go to rundown facilities “sends a message to kids that we don’t value their education, we don’t value them.” My research on noise and classroom education was conducted over forty years ago and it pains me that we are still faced with public school buildings that impede school learning. I applaud Rossi and Dempsey for highlighting the need to provide learning spaces that facilitate rather than hinder our children’s education.

Birds changed their tune during the Covid lockdown

In several blogs I have written recently, I commented that the pandemic’s effect on the soundscape did not just impact humans but other species as well, e.g. birds, whales. A recent article on a study of birds in San Francisco found that birds started singing differently during the silence of the COVID-19 Lockdown, noting that male white-crowned sparrows in San Francisco have begun to sing more softly and with an improved vocal range. The article says this change in singing may make them “sexier to females.”

The article cites a paper that has studied how animals, including whales and birds, have changed their behaviors during the pandemic shutdown. Before the pandemic, cities characterized by loud noises, especially from traffic, forced birds to sing louder to be heard by other birds. The authors reached this finding by comparing birdsong data collected previous years at the same sites they collected data during April and May 2020. Their data allowed them to conclude that birds “can adapt to changing environments.”

Erik Stokstad, writing for Science, states that birdsong “recaptured its former glory,” referring to the white-crowned sparrows of San Francisco. He adds that when birds sing louder in noisy environments the stress created “can speed aging and disrupt their metabolisms.” With the noise also preventing birds from hearing their own chicks, there is the possibility that bird diversity is less in many cities. Furthermore, by demonstrating that some birds can adjust their songs to their environment, it might be that birds who could not adjust, and as a result left noisier cities, might return to places that are now quieter. But the quieter time of the pandemic has passed as cities have been returning to noisier times. Thus, the birds that have quieted down will very likely have to increase the volume of their songs. Also, may I add, that it is unlikely the birds who left will return.

Stokstad interviewed Elizabeth Danberry and her behavioral ecologists who have studied white-crowned sparrows in and around San Francisco for more than twenty years. Their research has clearly demonstrated the impact of noise pollution on the health and well-being of these sparrows. Similarly, long standing research has also clearly found that noise is hazardous to human hearing, health, and well-being. So I ask, how much more research do we need linking noise to adverse effects on humans and other species before we begin to lower decibel level in our environment?

Brooklyn Navy Yard gives birth to quiet electric motorcycle

Founded in 1801, Brooklyn Navy Yard’s sprawling 350-acre site overlooks Manhattan and has seen a lot of innovation—including construction of the Civil War ironclad, USS Monitor https://brooklynnavyyard.org/about/history. At it’s peak during WWII, the yard employed 70,000 people. But ship building at the Yard ended long ago, and now it’s home to hundreds of innovative enterprises including a movie studio.

Among those companies is a young company called Tarform funded by a California venture-capital firm and conceived by a young New Yorker, via Stockholm, Sweden, named Taras Kravtchouk, an industrial designer who is building an absolutely gorgeous, all-electric motorcycle using sustainable materials. Even the motorcycle’s “leather” seat is made from plant materials, not animal hide, and there’s no conventional plastic either—because he’s found substitutes made from biodegradable, natural materials.

Of course, we’re interested because electric motorcycles do not use petroleum and are extremely quiet—as well as impressively powerful. But this bike is also unbelievably beautiful.

As Karavtchouk say, “[b]eauty is its own form of sustainability; no one want to throw away something gorgeous.”

There are a quite a number of electric motorcycles coming onto the market—including several models from American “hog” manufacturer Harley Davidson, whose company executives are aware that their stalwart customers—Boomers—are aging out of the market and GenX and Millennials are much more interested in quiet, powerful, electric rides. But the new Tarform is a real knockout in the looks department:


We have nothing to gain from praising it but just can’t pass up the opportunity to point it out.

How do we protect quiet?

Noise in Europe has been a concern of health authorities there for some years. In 2011, the WHO’s European office issued a report on the global burden of disease from noise and in 2018 issued Environmental Noise Guidelines.

Despite regulatory efforts, the European Environmental Agency reports that there has been no progress in making Europe quieter. This report from Euronews cites statistics from the EEA that 20% of the European population is exposed to levels of noise considered harmful to health.

Traffic noise is a major environmental problem. The COVID-19 shutdowns, however, caused a wave of quiet to spread across the globe. Scientists are calling this “the anthropause.” We have reported on the effects of reductions in human activity on seismic levels and noise levels in cities and the oceans, and Euronews reports that people noticed birdsong more than before.

How do we protect quiet?

One way to protect quiet is to preserve quiet spaces. The Euronews report also mentions two efforts we have mentioned before, Gordon Hampton’s Quiet Parks International and Dr. Antonella Radicchi’s HushCity app, which Euronews reports is being used by city councils in Berlin, Germany and Limerick, Ireland.

The Environmental Protection Agency was tasked with eliminating noise pollution in the U.S. by the Noise Control Act of 1972 and the Quiet Communities Act of 1978, but federal noise enforcement activities ceased during the Reagan era when the EPA’s Office of Noise Abatement and Control was defunded.

We hope that a future president will recognize the importance of quiet and restore funding for noise abatement and control in the U.S.

Lockdown was a boon for science

As I have written before on Silencity, the COVID-19 lockdown has given city dwellers around the world the opportunity to hear a landscape with less road traffic, fewer overhead jets, and a slowdown in constructions sounds. Yes, one sound was heard more frequently – birdsong. But on June 22, New York City is entering Phase 2 and the “older, less welcoming sounds” could be returning.

Interestingly, the quieter pandemic environment has given the Quiet Project in the UK the opportunity to map out the lower decibel levels that have occurred during the lockdown, writes Philip Ball of The Guardian. In addition to actual sound recordings, the Quiet Project has asked the public to reflect on how the changed soundscape has affected them. According to Lindsay McIntyre, the director of the company involved in this project, “[e]veryone I speak to has got an opinion on how the changes in noise makes them feel.” For example, as I have noted in earlier writings, some people actually miss the more traditional urban sounds, but what they really missed was what their lives were before the pandemic.

The researchers involved in the Quiet Project hope to use their data in ways that may result, for example, in having planners factor in more “tranquil areas” in cities as we move forward. Seismologists are especially interested in how the pandemic altered human activities. With less human activity, and the accompanying noises they are responsible for, seismologists can detect small earthquakes and this information can tell more about the “state of stress and movement in the crust.” Oceanographers, concerned about the impact of low-frequency noise from ship engines on the communications of marine life, found the change in ocean sounds during the pandemic provided the opportunity to study ship factors that harm marine animals. This finding could “help plan ocean transportation so it is less disruptive to marine life.”

With the pandemic resulting in less noise, scientists were given the opportunity to collect the kind of data that may help them find ways to keep our planet quieter in the near future for all its inhabitants. Out of adversity, can come creativity!

Making the world a quieter and better place

I wrote the other day about the eerie nighttime silence of a city so jolted by violence that its nightly curfew starts at 1:00 p.m. in the afternoon. We’re approaching the end of the third month of lockdown, with a gradual reopening of the economy in Los Angeles County, now the center of the coronavirus epidemic in California.

The “Groundhog Day” nature of life these days is getting old. When I know the evening schedule for our three Public Broadcasting System stations by heart, this is not a good thing.

But, as I tell my wife, things could be far worse. I’m not getting shot at when I go to the market to buy food, we’re not being bombed, we have food, water, gas, electricity, internet and cable TV, we’re not in a refugee camp. We’re in a house with a yard, not a small crowded apartment, everyone in the family is working, almost everyone from home,

I only knew one person who died from COVID at age 92, and one friend on the east coast who got COVID at work but has recovered.

We miss cultural events, museums, movies, restaurant dining, and travel, but again, things could be far worse.

I recognize that when for the foreseeable future the new normal for the U.S. is 20,000+ new COVID cases each day and another 1,000 deaths, noise concerns fade in importance, but they are still important.

I understand that as our country continues to be unable to control the COVID epidemic, as American democracy hangs by a thread, and the nation tries to deal with job losses not seen since the Great Depression, the environment is a relatively minor concern. But it is still a concern.

Several of The Quiet Coalition’s members have written about the reduction in noise, largely transportation noise, during the COVID lockdown with beneficial effects on people, birds, and ocean life. The only way we will be able to keep the quiet, to eliminate unnecessary noise, is to elect leaders and legislators who are concerned about the environment.

Those of use concerned about the environment should check now that we are still registered to vote. We should encourage everyone we know to do the same. And perhaps to file the papers to get a vote-by-mail ballot if that is possible where you live. I am already signed up to vote by mail.

Meaningful change may come from protests in the street, but peaceful and perhaps more meaningful change will come from exercising our franchise to vote at the ballot box.

Please register to vote and vote in November. This may be the most important election of our lifetimes.

Experts envision post-COVID cities without noise and pollution

Menios Constantinou, Architecture & Deisgn, writes about how the COVID pandemic and lockdown is giving us the opportunity to envision our cities without the twin scourges of noise and pollution. Constantinou interviewed Professor Mark Nieuwenhuijsen, a professorial fellow at the MacKillop Institute for Health Research and a leading environmental epidemiologist, who talked about how he noticed at the beginning of the lockdown that he could hear birds singing as the traffic noise had greatly diminished. Nieuwenhuijsen’s observation led him to reimagine what cities could be.

And he’s not the only one. Nieuwenhuijsen told Constantinou that “[w]hat you see in places like Milan is the policymakers taking advantage of the current situation, and using it as an opportunity to rethink how they plan their cities.” This is also happening elsewhere, with more than a dozen European nations backing a green post-pandemic recovery plan. The money can only be spent once, Nieuwenhuijsen adds, so “we might as well do it in the way that will save more lives in the long term, and create a more just, sustainable and liveable society.”

I’ve been wondering if this flashback we’ve been living in—flashback to what life may have been like before the industrial revolution—would produce any permanent changes when it’s over.

It’s a tough question to answer as we know so little about what happened after previous pandemics. For instance, the Great Flu Pandemic of 1918 was a social cost of the WWI mobilization–hat flu began with animal to human transmission in Kansas, spread east to Army recruitment centers, travelled abroad, exploded there and then returned to the U.S. in the tragically deadly second wave. And, of course the great plagues in Europe during the 14th to 16th centuries continued episodically for over 200 years because they didn’t have a theory of viral or bacterial disease or know they’re transmitted. That one, of course, then travelled across the Atlantic to North and South America with the Conquistadors and their soldiers and crews—ultimately destroying millions of lives and ending lost-established, indigenous civilizations.

This time we have the opportunity to learn from it. And there are encouraging signs that urban planners are embracing the idea that quieter, cleaner cities are possible, and what’s more, they’re highly desirable. Will that spur an acceleration in interest among city planners and others in doing more to regain that which has been lost to pollution and noise?

We can only hope that what Professor Nieuwenhuijsen comments will be heeded everywhere!

The quiet of the curfew

The protests over the death of George Floyd literally in the hands of the police have turned violent in many communities, including mine. The last two days the curfew has begun at 1 p.m., lasting until 5:30 a.m. the next morning.

Last night there were demonstrations and some looting and fires two miles to the east, and three miles to the west, but fortunately nothing happened in our city.

Once the low-flying helicopters stopped, and the distant sirens stopped, perhaps about 10 p.m., it was eerily quiet.

There were no passing cars or motorcycles or sirens heard though the open window.

As those who follow this blog post know, I am a passionate advocate for quiet.

But I wanted a little more noise last night. Just a little more noise…..

While some humans are complaining about the enforced, stay-at-home quiet we’re living through now, biologists are embracing this once-in-a-lifetime opportunity to research the impacts on other mammals, in particular, marine mammals.

I think it’s wonderful that scientists are using this window in time to compare how other species are doing while we’re locked indoors. Turns out, the researchers say, many animals are doing just fine!

This article in the New York Times provides glimpses into the “re-wilding” of cities around the globe as other species emerge to take over the world we’ve temporarily abandoned. And other videos actually prompt a sense of hope that the planet can heal itself if we’ll just give it a chance.

UK research shows trees help quiet your neighborhood

Ever wonder if trees actually help create quiet neighborhoods? Lots of people assume that if they plant a hedge or a row of shrubs that will help control noise. Professional noise control experts usually say, “no that doesn’t work.” But the UK’s BBC reported recently on some research showing that trees—particularly larches and conifers—actually help screen out noise.

The researchers tested 76 samples from 13 different tree species. Co-author Jian Kang, University College London, said that “[b]eside emphasising the effects of vision and shade, urban greening should be considered as well to achieve noise reduction during propagation.”

Here’s the catch–it’s not the trees’ leaves that are performing that service, it’s their bark. In other words, the noise they help control is actually noise traveling horizontally, like road traffic noise. They won’t do much at all for aircraft noise.

Since it’s the trees’ bark that’s performing the service, trees need to be planted pretty closely together to offer much real shielding from noise. Of course, trees also provide other kinds of relief: they screen out visual distractions like passing vehicles, nosy neighbors, etc., and they provide shade from hot sun in the summertime. So if what you really want is to have a quiet, pleasant front or back yard, do two things: put up a solid wall to stop the noise and other intrusions–wooden boards fitted tightly together will do–then put a row of trees or a hedge between you and the fence.

I lived for three and a half decades in Cambridge, Massachusetts, and even though it’s home to two universities, Harvard and MIT, it’s an intense urban environment with
an incredible amount of urban noise. I have had an eight-foot-high board fence on all sides of a relatively small property (houses in Cambridge are spaced pretty closely together).
That wall provided privacy, security, and a measure of solitude, even when we could hear noise on the other side of it.

One subsequently famous architect, Philip Johnson, built himself a simple, private house when he was a grad student in 1940 (he had a lot of money and it was his thesis project). He started by building a 10 foot high wall right at the property line that ran all the way around the property. Into the wall he inserted two tightly fitted, locking, windowless doors one at the front, one at the side. Then inside the fenced enclosure, he divided the whole lot into a flat-roofed indoor area and an open garden separating them with a glass wall that enabled wide open views of the garden from any place inside the house.

Simple, elegant, actually quite remarkable. That’s how you achieve solitude and privacy in an urban area! The house still stands today. In other words, wooden boards work even better than trees if you really want to screen out the noise and bustle of the city! Put in some trees for shade and green space and you’re done!
