We couldn’t agree more

Will Pulos,Time Out New York, writes about a common scourge of the city in “Loud-ass motorcycles in NYC are driving us completely bonkers.” Pulos talks about how they thunder out of the blue, “disrupting the peace of everyone in their nefarious paths,” all in a shameless attempt to get attention. He describes the assault of the erupting sound “that echoes through the streets with fury and arrogance,” and with a perversely exquisite sense of timing–striking just as you put the baby down in its crib or you pour yourself an end of the workday adult beverage. VROOM.

What adds insult to injury is the motorcyclist loudly screaming down an otherwise quiet residential street, setting off car alarms in his wake. We instinctively know that is not an accident. Which leads one to wonder when U.S. cities will embrace something akin to an ASBO for what is obviously anti-social behavior.

There is no social utility in purposefully loud motorcycles, so we might as well go after the low hanging fruit.

 

Do noisy leaf blowers drive you mad?

You are not alone. Linda Robertson, The Miami Herald, writes about the scourge that is gas-powered leaf blowers. Robertson interviews south Miami resident Vicki Richards, a violinist and “connoisseur of sound” who is tormented by them. Richards laments,”You can’t play over it and you can’t play with it. I used to have house concerts, but nobody wants to hear ‘String Quartet with Leaf Blower.’” Indeed.

The problem isn’t just their ubiquity–and in southern Florida they are a year round menace–it’s also the quality of their sound. As Robertson writes:

Maybe it’s the oscillating pitch of the snarl or the persistence of the whine. Maybe it’s the sheer volume that puts [Richards] over the edge. Leaf blowers. Can they even be said to produce sound? Or merely an abomination of sound?

Robertson explains that leaf blowers were meant to be a labor-saving device, but now have turned into the thing that many people hate–but not the landscaping company owners who fight efforts to ban the gas-powered models. No, they claim that costs would escalate and their livelihoods would be adversely affected if gas-powered leaf blowers were banned, in whole or in part. There is no evidence that this is the case, however. In fact, according to Quiet Communities, there are more than 100 landscape companies now operating with electric equipment and manual tools at prices that are competitive. Just recently, BrightView, the largest landscape company in the U.S. purchased 200 commercial grade electric mowers, citing the environmental and health benefits. It may only be a matter of time before electric is the new norm for both mowers and handheld equipment.

In the end, the economic arguments against banning these loud and filthy instruments of torture are likely to lose ground, because electric counterparts are getting better and better and more than pay for themselves over time. On the other side, there are very real concerns about air and noise pollution and the impact gas-powered leaf blowers have on workers’ and residents’ health and the damage they do to a neighborhood’s soundscape and eco-systems. Recently, the state medical societies in New York and Massachusetts passed resolutions about the dangers of gas leaf blowers, and the Centers for Disease Control and Prevention raised a warning about the noise levels and adverse health impacts of leaf blowers. As Vicki Richards asserts, “nothing compares to the dissonance of two leaf blowers going simultaneously that cuts through you like a serrated knife. That’s how you drive a person insane.”

The battle has just begun.

Are health concerns about gas-powered leaf blowers (GLBs) gaining momentum? On April 29th, the Massachusetts Medical Society (MMS) became the second in the nation to approve a resolution against GLBs, following the lead of the Medical Society of the State of New York (MSSNY). Other physician groups, such as Utah Physicians for Healthy Environment and Fresno Madera Medical Society, have also issued warnings on the use of GLBs and other fuel-powered lawn and garden equipment. The resolution brought by the society’s Committee on Environmental and Occupational Health and its chair Heather Alker, MD, MPH, recommends that the MMS:

  • Recognize noise pollution as a public health hazard, with respect to hearing loss;
  • Support initiatives to increase awareness of the health risks of loud noise exposure;
  • Urge the maximum feasible reduction of all forms of air pollution, including particulates, gases, toxicants, irritants, smog formers, and other biologically and chemically active pollutants; and
  • Acknowledge the increased risk of adverse health consequences to workers and general public from gas-powered leaf blowers including hearing loss and cardiopulmonary disease.

The growing concern on the part of the medical community over leaf blower noise is welcome news. Commercial GLBs can produce noise of 95 decibels and higher at the ear of the operator. This noise level exceeds safe occupational levels by an order of magnitude. The close proximity use of these powerful engines exposes both workers and others in the area to prolonged periods of excessive noise, not to mention toxic air pollutants. The presence of a low frequency component in the leaf blower’s frequency band distribution (i.e., the device’s sound signature) enables it to travel over long distances and through walls and windows.

The MMS resolution notes the harms to hearing and health from excessive noise produced by GLBs. Loud noise is known to cause hearing loss, tinnitus, and hyperacusis, as well as other health problems such as high blood pressure and heart disease. In addition, loud noise has negative effects on quality of life, communication and social interaction, work productivity, and psychological well-being.

The burgeoning use of GLBs and other fossil fuel powered equipment around our homes, schools, and other public spaces is a public health hazard, and a growing number of physicians and other health professionals are becoming concerned. The moves made by MMS and MSSNY are to be lauded, and other state societies and medical groups, including the American Lung Association and American Heart Association, need to prioritize this issue.  With the body of scientific evidence on the harms associated with noise and pollution, other state and national medical societies have a critical role to play in educating government officials and the public about the connections between environmental hazards and disease and the actions we can take to reduce risks in our communities.

There’s a booming market for fancy noise-absorbing objects

Want to take a guess why? Yes, open offices. Sarah Kessler, Quartz, examines the world of open offices and the designers who try to fix them, like Aaron Taylor Harvey, the head of Airbnb’s internal architecture and interior design group. So what does Harvey do to control the din at Airbnb? His team hung “a series of banners set two feet apart and made out of recycled cotton” from the ceiling of a large open space, wrapped surfaces with “sound-absorbing panels that look like fabric wallpaper, and strategically placed sound-absorbing walls to separate areas of noisy collaboration from those with quiet focus.”

But these are new, cutting edge tech companies. They aren’t going to be satisfied with those beige fabric covered cubicle frames that traditional corporations use.  No, today’s designers are making the banners like those used at Airbnb with recycled denim. “[T]hey’re ideal for companies, like Airbnb, that want to be environmentally friendly,” writes Kessler. One company makes “sound-absorption panels that look like wood, and sound-permeable paint that can help disguise a panel as a piece of art,” while another “builds sound absorption into lamps, furniture, and room dividers.”

No doubt the cost of all these high-end fixes are cheaper than, say, providing a quiet space to each of Airbnb’s employees, but at what point do corporate executives and their bean counters decide that maybe the best option is to provide employees with an office where they can actually get their work done?

An explainer on noise cancelling headphones:

How do noise cancelling headphones work? Royce Wilson, news.com.au, writes about noise cancelling headphones, the cure-all to our modern noisy world.  But have you ever wondered how they actually work?  Wilson reports that there are “two types of noise cancelling technologies for headphones — passive and active,” and he asked University of Queensland School of Information Technology and Electrical Engineering research fellow and lecturer Dr Konstanty Bialkowski about the different approaches.  Dr. Bialkowski said that the passive technology is “like having a cup around your ear that reduces high-frequency noise” (“people talking or high-pitched squealing”), while active cancellation is for low-frequency noise (e.g., low-pitched hum like a car engine, aeroplane engine or a fan).  With active cancellation, the headset, which has a microphone, “knows the distance between the microphone and your ear and it makes [a] complete opposite noise” to cancel out the distracting noise.

Is your home too noisy? Here’s a useful guide to help make your space more peaceful:

How to solve common sound problems in your home. Kate Wagner, a graduate student in Acoustics writing for Curbed.com, has written an interesting piece on room acoustics that is very accessible for the layperson.  She describes basic acoustic principles and examines common sound problems and solutions.  Whether the issue is your entertainment system or an open plan space, Wagner offers straight forward suggestions you can use to make your home as aurally comfortable as possible.

If you want to learn more about about sound absorption, reflection, diffusion, and transmission to see how they affect the sound quality of a room, watch this short and informative video Wagner linked to in her piece:

 

What’s the one thing never mentioned when discussing drone delivery?

 

Imagine 100 of these, overhead, constantly

Dyllan Furness, Digital Trends, writes about the U.S. military’s successful launch of “one of the world’s largest micro-drone swarms” in October in a piece titled, “The sound of 103 micro drones launched from an F/A-18 will give you nightmares.” Click the link to the piece and hit play on the video at the top of the page. The micro-drones can be heard starting at 2 minutes, 17 seconds.

We’re not sure if the sound will give you nightmares–although it is unnerving–but it did make us wonder about what would happen to our soundscape should Amazon and others succeed in convincing governments that drone delivery is a great idea. What you hear on the video is 103 micro-drones–small drones “with a wingspan under 12 inches.”  Now imagine a battalion of full-size, package-wielding delivery drones flying above your head. Just saying.

 

 

Despite complaints, restaurant noise continues unabated

by Daniel Fink, MD

Ever since I developed tinnitus and hyperacusis from a one-time exposure to loud restaurant noise, I have been looking for a quiet restaurant (see the Acknowledgements section at the end of my editorial in the January 2017 American Journal of Public Health, “What Is a Safe Noise Level for the Public?“).

It turns out I’m not the only one complaining about restaurant noise.

Restaurant noise is the number one complaint of diners in New York, San Francisco, Portland OR, and Boston.  In fact, the Boston Globe just recently wrote about diners’ dislike of restaurant noise in a piece titled, “Listen up: Restaurants are too loud!

Restaurant owners may think that noise increases food and beverage sales, and decreases time spent at the table, and they are right.  But what they cannot measure is how many meals are lost because people like me don’t go to noisy restaurants with family or friends, choosing to dine at home, instead, where we can converse as we enjoy our meal. Perhaps restauranteurs should consider that we middle-aged folks are more likely to spend money in restaurants than other demographic groups.  After all, for many of us our kids are done with college, our mortgages are paid off, we’ve been saving for retirement, and we have the disposable income to enjoy a nice meal out more frequently than in our youth.  If there were quieter restaurants, we might dine out more often instead of avoiding them because we would rather not have a side of hearing loss with our steak frites.

I guess that as long as the restaurants are busy, they will stay noisy. But if enough of us speak up–in the restaurants and to our elected representatives, asking them to pass laws requiring some limits on indoor noise–restaurants will eventually get quieter.

Dr. Fink is a leading noise activist based in the Los Angeles area.  He serves on the board of the American Tinnitus Association, is the interim chair of Quiet Communities’s Health Advisory Council, and 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.

Yet another article about the failure that is the open plan office:

Why Open Plan Offices Are Bad For Us. Bryan Borzykowski, BBC.com, examines the modern office worker’s nemesis, the open plan office. Borzykowski introduces us to Chris Nagele, a tech executive who adopted an open plan space because he thought it would encourage collaboration among his team members. But Nagele soon discovered that he made a huge mistake. Instead of a free exchange of creative ideas, Nagele found that everyone was distracted, productivity suffered, and his employees were unhappy, as was he.  And he wasn’t alone.

Borzykowski reports:

Professors at the University of Sydney found that nearly 50% of people with a completely open office floorplan, and nearly 60% of people in cubicles with low walls, are dissatisfied with their sound privacy. Only 16% of people in private offices said the same.

Sound privacy means noise.  Your neighbor’s phone call is noise to you, and your call is noise to him or her.  And in an open office, it’s possible to have lots of neighbors. No surprise then that in the U.S., where about 70% of offices are open concept, there is a growing backlash against them.  And there is research that backs up employees’ complaints.  Specifically, “that we’re 15% less productive, we have immense trouble concentrating and we’re twice as likely to get sick in open working spaces.”  That is, the reason employees hate open plan offices isn’t just a loss of status and exposure to a litany of minor nuisances. Rather, “we can’t multitask and small distractions can cause us to lose focus for upwards of 20 minutes.” That is, we can’t do our work.

In the end, the stated motivation for adopting open plan offices–to encourage collaboration–is a lie.  Many companies claim that motivation when the bottom line is that open plan offices are cheaper.  But even if encouraging collaboration really is the motivation, Borzykowski tells us that “we don’t collaborate like we think.”  Instead, he writes:

[I]t’s well documented that we rarely brainstorm brilliant ideas when we’re just shooting the breeze in a crowd. Instead, as many of us know, we’re more likely to hear about the Christmas gift a colleague is buying for a family member, or problems with your deskmate’s spouse.

So, what to do?  The obvious choice is to ditch the open plan office, but that isn’t easy to do after significant funds have been spent on a new space.  When the floor plan cannot be changed, some sort of accommodation should be made, particularly for jobs that require focus, like writing or coding.  Borzykowski reports that some companies “are experimenting with quiet rooms and closed spaces,” while others place sensors around the workspace to track noise, temperature, and population levels, allowing staff to “log on to an app [to] find the quietest spot in the room.”  Or maybe companies should bite the bullet?  According to Chris Nagele, leaving the open plan office behind resulted in his employees being happier and more productive.
