Caterpillars hate noise too

Erica Tennenhouse, Scientific American, writes about new research that shows traffic noise makes caterpillars’ hearts beat faster. Eventually, the article notes, the caterpillars become desensitized to the noise, but that comes at a price. Andy Davis, conservation physiologist at the University of Georgia, tells Tennenhouse that:

[The] desensitization could be problematic when the caterpillars become adults, Davis says. A rapid stress response is vital for monarch butterflies on their two-month journey to spend winters in Mexico, as they narrowly escape predators and fight wind currents. “What I think is happening [on roadsides] is their stress reactions get overwhelmed when they’re larvae and [could be] impaired when they travel to Mexico,” Davis says.

Every living thing is getting stressed out by our noise.

 

Noise is bad for your heart

by Daniel Fink, MD, Chair, The Quiet Coalition

Dr. Nandi, a health news commentator for television station WXYZ in Detroit, Michigan, explains why loud noise is bad for your heart.

Here’s a hint: it causes stress, and that causes high blood pressure, heart attack and heart failure, stroke, and death.

Dr. Nandi didn’t reference a recent article by Dr. Thomas Münzel from Germany in the current Journal of the American College of Cardiology, but I’m pretty sure that’s where he got his information. The Washington Post did speak with Dr. Münzel for its coverage of this topic.

Dr. Münzel’s new article is behind a paywall so only the abstract is available for free, but in it he and his colleagues updated information he wrote about in the European Heart Journal in 2014.

Dr. Daniel 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 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.

 

The CDC issues report on noise-induced hearing loss

and the facts are frightening. The Centers for Disease Prevention and Control’s (CDC) current issue of Vital Signs focuses on the dangers of noise on hearing health.  Among other things, the report states that:

  • 40 million Americans aged 20-69 years old have noise-induced hearing loss (NIHL). Hearing loss is the third most common chronic health condition in the US, and almost twice as many people report hearing loss as report diabetes or cancer.
  • 1 in 2 American adults with hearing damage from noise did not get it exposure to noise at work. Noise outside of work can be as damaging as workplace noise.
  • Too much loud noise, whatever the source, causes permanent hearing loss.
  • 1 in 4 Americans who report excellent hearing have hearing damage.  You can have hearing loss without knowing it.
  • The louder the sound, and the longer you are exposed to it, the more likely it will damage your hearing permanently.
  • Continual exposure to noise can cause stress, anxiety, depression, high blood pressure, heart disease, and many other health problems.

This fascinating if distressing report comes with easy to understand graphs and charts that clearly explain the dangers of noise exposure, who is most at risk, the high cost of hearing loss, how hearing loss occurs, and, most importantly, what can be done to prevent NIHL.  Because, in the end, one point is crystal clear: noise-induced hearing loss is 100% preventable.

As if air and water pollution weren’t enough:

Noise pollution from fracking may harm human health.  Brett Israel, UC Berkeley News, writes that “[f]racking creates noise at levels high enough to harm the health of people living nearby, according to the first peer-reviewed study to analyze the potential public health impacts of ambient noise related to fracking.”  What kind of health impacts?  The researchers found that “noise from fracking operations may contribute to adverse health outcomes in three categories, including anxiety, sleep disturbance and cardiovascular disease or other conditions that are negatively impacted by stress.”  One more reason to end fracking.  Click the link for a detailed description of the “complex symphony of noise types” associated with fracking activity.

Dying in noise:

Death. I fear dying – in noise.  An interesting article by Mai-Britt Beldam, who designs/manages acoustics in health care, about her father’s time in hospice, a Cambridge professor reduced to tears by a noisy hospital as he was dying, and her fear of dying in noise.

 

 

Why everyone–except the bean counters and upper management–hates open plan offices:

When All’s Not Quiet On the Office Front, Everyone Suffers.
