Havana mystery: Weaponized sound or ‘spooky action at a distance’?

Albert Einstein never accepted quantum physics, proving that geniuses don’t know everything. One phenomenon he couldn’t explain—now known as “quantum entanglement”–he simply dismissed as “spooky action at a distance.” But it has lately (decades after Einstein’s death) been proven.

Something else that’s not understood yet is the odd case of “weaponized sound” that appears to have sickened people at the U.S. embassy in Havana, Cuba. This piece in Wired Magazine, as well as this article in The New York Times, are by far the best so far on this mysterious and unexplained situation.

If you, like we, have been pondering this, wondering if an LRAD was involved or perhaps some secret source of weaponized infrasound or ultrasound, don’t expect a definitive answer just yet. Adam Rogers, the author of the Wired piece, and Carl Zimmer, of The New York Times, dug deeper than most and even talked to some scientists (in the U.S. and Russia) to see what, in anything, anybody knows. The answer is this: it’s still a mystery, but stay tuned because they’re gradually eliminating possibilities. The most probable scenario involves a combination of ototoxic chemical exposure with some form of weaponized sound. Yes, there are many ototoxic chemicals and drugs, that is, chemicals and drugs the exposure to which can destroy your hearing, including several chemotherapy drugs.

Is this kind of lethal combo possible? Probable? Likely?

Whatever it is, it apparently is NOT an LRAD. Yes, it’s true that LRAD’s are being distributed to and used by police forces since 2009, but whatever has been going on in Havana, that’s not the answer. Stay tuned.

Researchers confirm cheaper hearables work as well as hearing aids

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

Several Johns Hopkins researchers reported some research in the Journal of the American Medical Association that tested the notion that a cheap ($200-$400) unregulated “hearable” (also known as a personal sound amplification product or PSAP) may be a convenient and inexpensive alternative to a hearing aid.

The researchers tested a handful of the new hearable products just coming on the market and, sure enough, they perform as well as, or nearly as well as, expensive ($2000-$5000 per ear) hearing aids made by the “Big Six.” The Big Six are six companies that have controlled the hearing aid industry; their products are regulated in the U.S. by the Food and Drug Administration.

Recently legislation passed by Congress and signed into law just before the August recess, about which we have written earlier, requires the FDA to de-regulate, i.e. to take a hands-off approach to this new class of high-tech hearing devices. As a result, these new products can be sold over the counter, without a prescription.

Will you need to take them to an audiologist to get them fitted? Certainly you may choose to do so, and that may be the best option, particularly if you are concerned that improper use might endanger your hearing. But with a conventional hearing aid, patients were required to pay professional fees to an audiologist for fittings, etc., resulting in a bundled price that made the hearing aids unobtainable for many people who needed them. You can certainly expect to read articles claiming that these new devices pose a danger. Henceforth, it’s up to the consumer to decide—as he or she already does with regard to many other healthcare products, including over-the-counter drugs that formerly required a doctor’s prescription.

We say caveat emptor (buyer beware), but welcome these new products that cost 1/10th the price of conventional hearing aids. They are suitably priced to be able to meet the needs of 48 million Americans with noise-induced hearing loss, many of whom cannot afford the $4000 to $10,000 price tag for conventional hearing aids. Voters seem to want de-regulation—this is it!

Tracking those noisy airplanes flying over your house

by Daniel Fink, MD, Chair, The Quiet Coalition

As The Quiet Coalition has reported, people living all over the country have complained about airplane noise in the last few years. This is a result of flight path changes promoted by the Federal Aviation Administration’s (FAA) NextGen program, which guides airplanes on more direct flight paths, saving time and fuel and making flying safer. Unfortunately, the FAA forgot to consider what happens to the people living below these newly concentrated flight paths, who are subjected to a barrage of aircraft noise.

The screenshot above shows the concentration of aircraft over the Los Angeles, California area.  Not surprisingly, newspaper and television reports have documented these problems in Washington, DC, Baltimore, Boston, Phoenix, San Francisco, and several cities near Los Angeles, and Orange County, California. I’ll stop there, but there are many more complaints in and around the 86 major airports in the U.S. In fact, the FAA just reported that it has received over 40,000 complaints of airplane noise from residents living near Washington DC airports.

In dealing with government agencies and elected officials, I have found that the best way to get someone to act is to document a problem as completely and as often as possible. For aircraft, that means reporting the date and time of the overflight, and ideally identifying the airline and flight number of the plane. I didn’t know that was possible until I was walking with a friend who pulled out her cell phone as an airplane flew far overhead, pointed it at the plane and said, “that’s the Qantas flight from Sydney.”

She showed me the Flightradar24 app that she had downloaded to her phone (a screenshot appears above). It identifies planes flying overhead, including the carrier, flight number, and type of airplane. There are several different levels of technology that can be purchased, obviously with more features costing more, but the basic app is free. There also are other flight tracker apps, but Flightradar24 appears to be best for this purpose.

If airplane noise is a problem in your neighborhood, get the app, start collecting data, and report it to your local council representative, congressional representative, local Quiet Skies organization, the FAA (contact them online here), and your local airport. Include the date and time, airplane identification data, and a decibel reading, if possible, using a sound meter app. At busier airports, flights depart every few minutes from early morning until almost midnight. Enlist a group of neighbors to take designated time slots to document the aircraft noise problem, or make documenting the problem a school science project. It’s hard to argue with the data.

Aircraft noise is a major health hazard, causing hypertension, diabetes, cardiovascular disease, hospitalization, and death. Fighting aircraft noise will require accurate data, and Flightradar24 may be the way to get it.

He serves on the board of the American Tinnitus Association, is the interim chair of Quiet Communities’s Health Advisory Council, and is the founding chair of The Quiet Coalition, an organization of science, health, and legal professionals concerned about the impacts of noise on health, environment, learning, productivity, and quality of life in America.

Here’s the best mass-media article on noise-induced hearing loss

Despite impacting 48 million Americans, noise-induced hearing loss (NIHL) has languished in the shadows for decades. But that’s changing! Check out the 17-page beautifully illustrated article in the September issue of Real Simple magazine*, a Time/Life publication with 8.5 million readers nationwide (that’s eight times larger than the New York Times readership of 1.1 million).

If you’ve been looking for a “quick overview” you can hand to friends and family who fail to understand America’s unrecognized problem with hearing loss—whether it’s your kids’ and their constant earbud (ab)use, friends who can’t understand conversations when you’re dining out, or an elderly relative who’s stopped paying attention and is increasingly depressed—this article should get the conversation started. And if they ask “what else can I read about this?” Tell them to look at this issue of Scientific American, new information from the Centers for Disease Control, and this one-page Fact Sheet on the health effects of noise that The Quiet Coalition (TQC) published in 2016.

It’s clear that NIHL is, as TQC’s chair, Daniel Fink, MD, says, “a growing problem in America nearing epidemic proportions.” But there’s a lot of work to do to get people (including the nation’s leaders) to understand that this is a legitimate public health problem. Frankly, the European Union and Asia are far ahead of us on this issue.

In the meantime, take heart: major media are beginning to notice! Congratulations to the editor of Real Simple for recognizing this growing health crisis. We are extremely grateful that her magazine cited three of TQC’s Steering Committee experts in this piece–Rick Neitzel, PhD, Arline Bronzaft, PhD, and Bradley Vite–and also
described two practical success stories. We hope Real Simple will continue to cover this issue and give it the attention it deserves.

We have only one complaint: the magazine erroneously states that 85 dB is the threshold of hearing damage. In fact, research has shown that permanent hearing damage starts at noise levels as low as 75 dB; furthermore, non-audiological health effects, such as cardiovascular effects, can be caused by noises as low as 55 dB.

*NOTE: the best place to find Real Simple magazine may be at the checkout counter at Whole Foods or a local book store. Or you can get it here.

A Pocket Guide to Soundwalking

By Antonella Radicchi, PhD, Steering Committee Member, The Quiet Coalition

I’m pleased to share “A Pocket Guide to Soundwalking,” my essay on soundwalking written especially for newcomers to soundwalking, such as architects, city planners, and policy makers who are interested embracing a holistic and human-centered approach to “city sense and city design.” But my guide is also dedicated to anyone interested in learning about soundwalks, their purposes, how they are designed, and how they are performed.

In the words of Hildegard Westerkamp, a composer and musician who, since the Sixties, has contributed to the definition and spread of soundwalking, a soundwalk is “any excursion whose main purpose is listening to the environment.” Soundwalks have a long history with a consistent body of literature and established practices, especially in the field of sound studies and acoustic ecology where they have been used as educational tools for enhancing sonic awareness and listening skills. But in the past decade especially, they have also been used as a method of inquiry in urban planning and soundscape research projects, and they have employed both solo and group soundwalks.

Against this background, I’ve traced historical notes and drafted a preliminary list of criteria for designing a soundwalk that will be useful for diverse fields of research. My pocket guide to soundwalking proposes specific and diverse methods of soundwalking, drawn from literature review and my practice, and according to the civic, education, and research goals.

A Pocket Guide to Soundwalking” has been recently published in a fantastic book on urban economics, “Perspectives on Urban Economics” (eds Besecke et al.), which “offers a broad palette of perspectives on the multi-layered field of urban and regional economics.” The book pays tribute to Prof. Dr. Dietrich Henckel, who held the Chair of Urban and Regional Economics at TU Berlin’s Institute of Urban and Regional Planning from 2004 to 2017, “and contributed passionately to a wide range of discourses.”

Quiet race cars? Yes! “Formula E racing” is a hot new world sport

Race cars are supposed to be LOUD right? I grew up fascinated by Formula 1, Grand Prix racing and the incredibly loud Indy 500—all of which necessitated the use of hearing protection. But no more. In 2014, a new class of all-electric race cars called “Formula E” emerged and began racing in various venues around the world. France, of course, now holds an annual “ePrix,” and Los Angeles was the first city in the U.S. to host a Formula E race. But on July 16th of this year, Brooklyn hosted an exciting one.

If you’re a car nut like me, who’s also concerned about air and noise pollution, this is the sport for you!

Here’s a list of Formula E events in 2017 and the schedule of races in 2018.

Enjoy!

Quiet motorcycles? Tell your neighbor to buy one of these…

You may be thinking, “quiet motorcycles…how is that possible?” In fact, they already exist—but you might have trouble getting a Harley-riding neighbor to embrace them. For many bikers, noise equals power. But in the case of electric motorcycles there is reason to believe that quiet is powerful too!

Lithium ion battery-powered motorcycles are gaining favor–Consumer Reports is impressed with them. Furthermore, the Department of Defense’s Advanced Research Projects Agency (DARPA) has been working on camo-painted, “stealth” hybrid gas/electric off-road motorbikes.

Motorcycle noise is a serious problem—especially for people who suffer from auditory disorders like partial hearing loss, tinnitus, hyperacusis, and misophonia–for whom the racket from motorcycles can be excruciatingly painful. This may be bikers themselves or people who live in neighborhoods that are regularly exposed to this type of noise. Several years ago, the U.S. National Academy of Engineering (NAE) convened a meeting about the problem of motorcycle noise and issued a report in 2014, though it seems to have fallen on deaf ears outside the NAE.

The noise has become such a problem in so many communities that even Harley-Davidson’s CEO has spoken out about Hog riders who remove their factory mufflers and install ‘straight pipes.’ Officially, the company doesn’t approve of owners tampering with the factory-installed mufflers, but after-market manufacturers are all-too-willing to meet consumer demand for more noise. The best news is that Harley-Davidson is developing an electric-powered motorcycle too.

Motorcycle noise may be a problem that regulation simply cannot fix. Given the current situation, it is unlikely the Environmental Protection Agency will be able to do anything about it. Instead, The Quiet Coalition (TQC) recommends framing motorcycle noise as a public health issue and encouraging a positive, technology-centered approach by businesses:

  • Become familiar with the large body of scientific literature indicating that loud noise is a public health problem. Authorities, including the U.S. Centers for Disease Control, publicize this information on their websites. Like tobacco smoke a generation ago, it will be necessary to engage public health officials before the motorcycle noise be addressed.
  • Urge individuals and groups that oppose motorcycle noise to encourage businesses to develop quieter, electric-powered alternatives. They are cheaper to operate (solar power is getting cheaper by the minute!) and much easier to maintain or repair (fewer moving parts!).

We believe these two steps are the best, most practical way to get action on this contentious issue and can actually lead to results. For example, The Quiet Coalition’s host, non-profit Quiet Communities, has been helping communities make the quiet transition away from fossil-fuel powered devices (namely landscape maintenance equipment) and towards advanced electric equipment and manual tools and emphasizing the compelling business model for users: the new lithium-ion-powered alternatives are cheaper to operate and maintain, they reduce air pollution, and they operate quietly. For some bikers, adopting technologically advanced, non-polluting, quiet alternatives may be appealing, especially if they have had health and hearing problems related to noisy bikes. It would be the start of a movement.

At TQC, we’re cautiously optimistic.

National Parks: Why quiet matters

By David Sykes, Vice Chair, The Quiet Coalition

On May 4, Science and Phys.org™ published news reports about a recent, significant, multi-year study about the pervasiveness of noise pollution in 492 national parks and natural areas across the U.S.

In “Noise Pollution is invading even the most protected natural areas,” Science writer Ula Chrobak notes that:

The great outdoors is becoming a lot less peaceful. Noise pollution from humans has doubled sound levels in more than half of all protected areas in the United States—from local nature reserves to national parks—and it has made some places 10 times louder, according to a new study. And the cacophony isn’t just bad for animals using natural sounds to hunt and forage—it could also be detrimental to human health.

Under the study, researchers from the National Park Service and Colorado State University “recorded noise at 492 sites across the country with varying levels of protection, [and] used the recordings to predict noise throughout protected areas in the rest of the country.” They also estimated naturally occurring ambient noise and compared the noise levels with and without humanmade noise. The results were damning: noise pollution doubled sound levels in 63% of protected areas and caused a 10-fold increase in 21% of protected areas.

And the impacts of that noise pollution affect all living things withing these areas.  Phys.org reports interviews Rachel Buxton, the study’s lead author and post-doctoral researcher, who states that “[t]he noise levels we found can be harmful to visitor experiences in these areas, and can be harmful to human health, and to wildlife.” The noise pollution findings means that “noise reduced the area that natural sounds can be heard by 50 to 90 percent,” which “also means that what could be heard at 100 feet away could only be heard from 10 to 50 feet.”

So what is the impact on humans and wildlife?  Phys.org explains:

This reduced capacity to hear natural sound reduces the restorative properties of spending time in nature, such as mood enhancement and stress reduction, interfering with the enjoyment typically experienced by park visitors. Noise pollution also negatively impacts wildlife by distracting or scaring animals, and can result in changes in species composition.

High levels of noise pollution were also found in critical habitat for endangered species, namely in endangered plant and insect habitats. “Although plants can’t hear, many animals that disperse seeds or pollinate flowers can hear, and are known to be affected by noise, resulting in indirect impacts on plants,” said Buxton.

The study results have been widely reported, showing that there is real interest in protecting our national parks and natural areas.  Researchers know that “many people don’t really think of noise pollution as pollution,” but they hope that this study will encourage more people to “consider sound as a component of the natural environment.”

The National Park Service’s huge portfolio of parks and natural areas provides a huge canvas for researchers concerned about the impacts of “noise pollution.” You may be surprised to learn that the National Park Service has a research division called “Natural Sounds and Night Skies Division” that has been looking for several years at the effects of noise not only on visitor experiences, but also on plants and animals. Their work is fascinating and resulted in a 2014 report from the National Academy of Engineering called “Preserving National Park Soundscapes.

Looking for a quiet restaurant? Wall St. values this “quiet” chain at $7.5 billion

By David Sykes, Vice-chair, The Quiet Coalition

Yearn for a quiet spot to dine where you can chat (or read) without clamour? If that seems hopeless in America’s noisy restaurants don’t give up—change is on the way.

It’s true that for decades restaurants in America have gotten louder and more cacophonous on purpose. Why? Restaurateurs and their designers say data show that profits climb when noise levels are high because their patrons are:

  1. attracted by the “buzz,”
  2. drink more alcohol,
  3. consume more food faster, and
  4. leave quickly, allowing more patrons to sit down and repeat the process.

True or not, those crowded, noisy eateries are designed to be that way. The good news is that, just as easily, they can be designed to be quiet. The bad news is that so many restaurateurs still don’t understand that the racket drives away large groups of potential patrons, and also alienates restaurant reviewers, some of whom now even carry sound level meters.

Is there such a thing as a successful quiet restaurant chain? One that profits from allowing patrons to converse with each other or read a book, or put a laptop on the table and work quietly–even at peak dining hours? Amazingly, yes. It’s one that already has 2000 stores, is the hottest “fast-casual” chain in America, and is growing faster than Starbucks. The name? Panera. Panera’s stores don’t pretend to be fashionable bistros nor do they serve alcohol. But the food is healthy, natural, fresh, and tasty and the atmosphere is definitely—and, according to acoustics experts, very consciously—designed to provide a haven where people can enjoy quiet conversations and each other without cacophony.

Quiet dining matters to lots of us—more folks than you might imagine. In fact, about 20% of people in their 20s suffer from hearing disorders (which can include hypersensitivities to noise with names like tinnitus, hyperacusis, and misophonia, conditions that make it impossible for them to enjoy restaurants or clubs). And about 50% of people in their 60s and an extraordinary 90% of people in their 80s suffer from an inability to understand speech when background noise levels are elevated. These are not “fringe” groups. Collectively, there are 40 million Americans who probably avoid dining in restaurants because they literally can’t stand the noise.

Do restaurant owners understand that? If they did, they might create quiet sections to broaden their market appeal. Many apparently do not. For those who do, the market opportunity may be considerable.

It just could be that “quiet dining” is the next trend.  For customers looking for quiet, the prospects are mouth-watering.
