The best headphones for children? None!

by Daniel Fink, MD, Chair, The Quiet Coalition

This post on the Parentology.com site discusses the best headphones for children in 2019. I disagree strongly. The best headphones for children are none at all! Why? Two reasons, one for auditory health and one for the child’s social and intellectual development.

First, for auditory health, headphones using the industrial-strength 85 decibel noise exposure level as a “safe” volume limit for a child’s tender ears isn’t safe. The UK’s Advertising Standards Authority ruled again Amazon advertising these headphones as safe for hearing because they’re not.

Second, allowing a child to isolate him or herself with headphones, first while watching a video on a device and then when listening to music when older, doesn’t allow the child to interact or communicate with others. And for the older children, the parent has no idea what the children are listening to.

Audiologists already report seeing younger patients with hearing loss and tinnitus instead of the senior population they are used to caring for.

And an epidemic of noise-induced hearing loss and other auditory problems appears to be certain in the near future.

Acoustic vehicle alerts are a problem

The Quiet Coalition’s Jeanine Botta presented a paper on acoustic vehicle alerts, also known as horn-based alerts, on May 13, 2019, at the Acoustical Society of America’s 177th meeting in Louisville, Kentucky.

Acoustic vehicle alerts are a problem because they are capable of disrupting sleep and interrupting concentration. In most vehicles, the alerts can be turned off or can be configured to use flashing lights instead of a sound. But not all horn-based alerts are easily reconfigured.

In 2011, the Society of Automotive Engineers recommended that automakers install “an externally audible or visual alert” to warn drivers of an engine that has been left running, as a means of preventing carbon monoxide poisoning. In response, some automakers used horn sounds to comply with the standard. This decision did not consider driver behavior or technical errors, such as drivers starting a car and getting out to brush snow off a windshield, or a passenger with a second key remaining in a car. This paper examined posts in online forums that include those authored by car owners seeking technical advice about turning off this horn-based alert. One frequently cited reason was concern over waking nearby neighbors.

In February 2019, Senator Richard Blumenthal introduced legislation requiring automatic engine shutoff in all vehicles in certain situations. The Protecting Americans from the Risks of Keyless Ignition Technology Act, or PARK IT Act, is supported by Advocates for Highway and Auto Safety, Center for Auto Safety, Safety Research and Strategies, and Consumer Reports.

And in California, where I live, where there are 14.5 million registered motor vehicles, it’s actually illegal for a horn to be used other than to avoid an accident or as a burglar alarm.

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.

Two thumbs up for noise-canceling headphones

Geoffrey Morrision, writing for the New York Times, casts his vote in favor of using noise-canceling headphones when traveling, and I’ll add mine, too. The only downsides of noise-canceling headphones is that the over-ear ones are a little bulky, they are yet another thing to pack and carry, and it can be hard to find a comfortable head position with them on when trying to sleep. But in return, one has much greater quiet when flying.

Aircraft cabin noise is largely low-frequency noise, from engines and airframe, and most noise-canceling headphones do a good job of reducing low frequency noise.

I often use them on longer train rides, too, where again the predominant noises are low frequency ones.

The best noise-canceling headphones are expensive, of course, but if you are a frequent flyer, they are worth it.

Restaurant noise in the news once again

This article by Ellie Violet Bramley in The Guardian discusses the ongoing problem of restaurant noise. Bramley interviews Greg Scott, founder of the SoundPrint app, who discusses the problems those with hearing impairment encounter trying to understand speech in a noisy environment. But as Bramley notes, the inability to clearly hear one’s companions is a problem for those with normal hearing, too.

Apparently some restaurant operators are getting the message, though. As Bramley concludes, people want restaurants in which they can converse easily with their dining companions.

Why you temporarily hear muffled sound after a loud noise

Noise-induced temporary threshold shift, or NITTS, describes the temporary muffling of sound after a person is exposed to loud noise. This article from the American Association for the Advancement of Science’s Eureka Alert details a report in the prestigious scientific journal Proceedings of the National Academy of Sciences, that provides an explanation for NITTS. Namely, researchers in Sweden found changes in calcium ions in the tectorial membrane of the cochlea.

While NITTS is a real and observable finding, the idea that auditory damage from noise is temporary is most likely false. Research by Liberman and Kujawa and colleagues at the Massachusetts Eye and Ear Infirmary strongly suggests that there is no such thing as temporary auditory damage. And decades of occupational noise exposure studies show that NITTS eventually becomes NIPTS, noise-induced permanent threshold shift, i.e., noise-induced hearing loss. That is, your awareness of muffled hearing following exposure to loud noise is temporary, but the damage caused by the loud noise is permanent.

Noise-induced hearing loss is 100% preventable. Avoid noise exposure and if one can’t avoid noise exposure, use hearing protection devices.

Because if it sounds too loud, it IS too loud!

Lawyer writes about leaf blower hazards

It is well known that leading commercial leaf blowers produce deafening noise levels of 100 dB or more at the ear of the operator and that the low frequency sound and vibration affect overall health. These, coupled with toxic and carcinogenic exhaust, put workers at risk for problems ranging from hearing damage, to irreversible neurological damage, heart disease, and cancer. Nevertheless, many workers do not wear protective gear and may not be aware of the risks they face.

Workers compensation law, a subset of tort law, allows injured workers to sue for medical care and compensation.

In this post at Lawyers.com, attorney Brian Allan Wall from McCann and Wall, Philadelphia, Pennsylvania, reviews the hazards of gas leaf blower use.  His piece shows that the legal community is aware that leaf blower noise can damage hearing and non-hearing health. If state and federal regulators won’t regulate leaf blower noise, maybe a series of workers comp lawsuits will force land care companies to either use battery electric blowers, reduce the use of gas blowers, or force manufacturers to make quieter machines.

Aircraft noise is a problem inside the plane, too

by Daniel Fink, MD, Chair, The Quiet Coalition

This piece in the Wall Street Journal discusses the problem of noise inside the airplane cabin, not just under Federal Aviation Administration’s NextGen flight paths.

Airplane cabins can be made quieter. The Airbus A380, soon to stop production, is the largest passenger airplane and also one of the quietest inside. Maybe other aircraft manufacturers can do more to design quieter planes, too.

Until they do, I will continue to wear my noise-cancelling headphones when I fly.

I recommend that you do the same.

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.

Noise affects children’s learning

by Daniel Fink, MD, Chair, The Quiet Coalition

This wonderful piece by noise pioneer Arline Bronzaft, PhD, one of The Quiet Coalition’s founders, summarizes her work and the work of others on how noise affects children’s learning.

Noise interferes with human function by disturbing concentration and interfering with communication. The EPA determined that “library quiet”– that is, a 45 dBA ambient noise level–is necessary to allow 100% speech intelligibility (see text at Figure D-1). Not surprisingly, when transportation noise intrudes into the classroom, children can’t hear what the teacher says, and this interferes with their learning.

Dr. Bronzaft’s article includes links to her groundbreaking work.

The Acoustical Society of America and the American National Standards Institute developed a standard for classroom acoustics, and more information is available at this link.
