Noise Pollution: Shhhhhh!

We live in a world that’s filled with noise. But when things get
too loud, the sounds can affect us in all kinds of ways. Kyle
Norris talks to one man who says that loud noises are a health,
ethical, spiritual, and environmental issue:


For Les Blomberg, it all started with a sound like this:


(Sound of Blomberg imitating buzzing)


That’s Blomberg imitating the sound of the street sweeper. It
would clean his street at four in the morning. Blomberg says he
had never thought much about noise pollution…until this
happened, and it made him all tired and cranky. Eventually
Blomberg got the city to change the time of day when it cleaned
the street.


This experience got him interested in the topic of noise
pollution:


“To me kind of at the core, noise is an issue of civility. How
you treat your neighbor. It’s an environmental issue. Noise is a
pollutant that we’re casting out. It’s a waste product. It’s kind of
like second hand smoke. It’s the waste product of our activities
that we’re casting out into the environment.”


Blomberg’s passion for noise pollution grew as he learned more
about it, and he realized it’s an under-rated, under-appreciated
problem. Now he runs the Noise Pollution Clearinghouse. It’s
an organization that tries to keep the peace and quiet, the
organization connects people with noise experts and activists.
It fights for stronger noise regulations and standards, and it tests
consumer products to find out which are the quietest.


Blomberg says people usually contact him with one of three
kinds of noise problems. Jets and helicopters (sound of jet),
highway noise (sound of highway), and noises from electronic
amplification (sound of music) — like loud stereos. People tell
him these noises ruin their sleep, concentration, and quality of
life… and all those things put people in bad moods and can ruin
how they deal with other people.


Loud noises also trigger a physiological response in our bodies.
That’s what Les Blomberg says:


“When we were evolving, when things were noisy it was
usually a warning that something wrong was happening. If the
lion walk through camp and you didn’t hear it coming, you
would be breakfast for that critter. And so we evolved to deal
with that. Our hearing works twenty-four hours a day, it can
wake us up if we hear noises in our environment.”


As humans evolved, Blomberg says that loud noises would
trigger a quick little shot of adrenaline, leading to fight or flight.
He says we still go through this stress response today, when we
hear a loud noise, even though we know it’s only a siren or an
air conditioner and not a lion.


Loud, isolated noises like a street sweeper or a leaf-blower can
be temporarily problematic, but if you’re continuously exposed
to loud noises like these over time, they can lead to serious
damage. Each year in this country 30 million people suffer
from hearing losses.


Paul Kileny is the Director of Audiology & Electrophysiology
at the University of Michigan’s Health System. He says hearing
is the essence of human communication:


“People who have significant hearing loss they have a variety of
emotional problems. They withdraw. They isolate themselves
because they have trouble hearing. They don’t socialize.”


So loud noises aren’t just an inconvenience. They can bring
about real emotional problems. Les Blomberg with the Noise
Pollution Clearinghouse says we don’t have to live in a noisy
world. Technology has the ability to make things quieter.


Noise-cancellation systems and acoustic buffering can make
cars, appliances, and even lawn equipment quieter. Engineers
can make road surfaces quieter to drive on, but these changes
cost money and will have to come from the various industries
wanting to change.


Blomberg says that’s starting to happen, but slowly. He believes
loud noises are also an ethical issue. He says it’s like the golden
rule, of treating people the way you’d like to be treated and that
we can all do a “politeness check,” by making sure we’re not
imposing our sounds on our neighbors.

NEW JET ENGINES EMIT MORE NOx

Although commercial airlines have been replacing their fleets with jets that are quieter and more fuel efficient, the engines actually emit more of certain pollutants. The Great Lakes Radio Consortium’s Lester Graham explains:

Although commercial airlines have been replacing their fleets with jets that are quieter and more
fuel efficient, the engines actually emit more of certain pollutants. The Great Lakes Radio
Consortium’s Lester Graham explains:


The federal government’s watchdog agency, the General Accounting Office, issued a report that
finds many airports have worked to reduce air pollution. Some have converted airport ground
vehicles to cleaner burning fuels. Newer jet engines emit less carbon monoxide and
hydrocarbons. But, they produce higher amounts of nitrogen oxides than engines on the older
models. As much as 40-percent more during landings and take offs. Those emissions contribute
to ozone pollution. That’s helping to keep more than half of the nation’s major airports in
violation of the federal ozone standards.


The General Accounting Office noted there are technologies available to limit nitrogen oxides
emissions from some of the newer aircraft models. Many government officials indicate that will
likely have to be the next step if ozone pollution around the airports is to be reduced.
