Are You Protecting Your Child's Hearing Properly?
5.2 million 6-19 year old have hearing loss directly related
to noise exposure*. Don't let your child be part of this unfortunate
group.
PEACE & QUIET
"Offer your child peace and quiet," says the Noise
Center. "Noise poses a serious threat to
children's hearing, health, learning and behavior." (And
I can't think of an adult who functions well in a noisy environment
either.) "Peace" and "quiet" usually go
together because without "quiet" there can be no "peace."
Aside from turning down the TV and stereo, lowering your voice,
and providing the
opportunity for quiet time in both their work and leisure,
take a look at the toys you allow your children to play with.
Fortunately my children didn't suffer hearing loss from the
obnoxiously loud toys they played with, but I must admit I told
them to quit for my sake, not theirs, and I was always
standing a good bit father away from their toy than they were.
One father I know immediately disarms any noise-making function
on a toy his child receives, and this may not be a bad idea.
And because they're young doesn't work in this case. You might
assume, for instance, that your teenager can take that 85 decibels
(dB) music because he's a teenager, but that isn't the case.
Children's ear canals are shorter than adults, and therefore
more vulnerable to damage in this way.
A study conducted by the Henry Ford Health System found that
many current toys, including tape recorders, bike horns, cap
guns, and toy telephones, are not safe for your child's hearing.
Of the 25 they tested, more than half of them made sounds higher
than 115 dBs.
According to The National Institute for Occupational Safety
and Health, at 110 dB, the maximum undamaging exposure time
is one minute and 29 seconds.
NOTE: In researching this article I found a variety of decibels,
as well as length of exposure before damage and also read studies
saying that individuals varied in their tolerance for noises.
The data is not consistent, but will give you a range. Should
you be wondering what protection to take when, ask your personal
healthcare professional for medical advice.
PERMANENT INSTANT DAMAGE
The ear is more unforgiving than you may know. A loud enough
noise can cause instant, permanent damage, some noises can cause
damage if heard long enough, and there is also cumulative effect
over time. Prevention is crucial because noise-induced hearing
loss can't be corrected, and hearing aids don't do much good.
Sound is vibration and has three properties: intensity, frequency
and duration. "Intensity" is what is measured in decibels
(dBs). A measure called dBA indicates damage to hearing. The
higher the dBA number, the greater the risk of damage to hearing.
This is because intensity translates to pressure on the eardrum.
What sound has what dBs? There is a long list of dBs (which
they equate with dBAs) on the League for the Hard of Hearing
website ( http://www.lhh.org/noise/decibel.htm ), including
various recreational and work situations. A noisy squeeze toy
rates an alarming 135dB from them.
"Noise levels above 85 dB will harm hearing over time,"
they caution, and "noise levels above 140dB can cause damage
to hearing after just one exposure." 140dB is also the
pain threshold; most of us hearing a sound at this level will
feel it as well. All values are approximate.
According to www.dangerousdecibels.org , harm can occur with
103 dBs after 7.5 minutes, 106 dBs after less than 4 minutes,
109 dBs after less than 2 minutes, and 115 dBs after around
30 seconds.
Here is a list of sounds and the decibels to give you an idea:
·0 The softest sound a person can hear with normal hearing
aka "hearing threshold" ·10 normal breathing
·20 whispering at 5 feet, broadcasting studio, rustling
leaves ·30 soft whisper, library ·50 rainfall,
light traffic, average home ·60 normal conversation,
air conditioning unit ·80 alarm clock ·85 noisy
restaurant ·90 city traffic ·110-120 rock concert,
speedboat, headphones on maximum ·110 shouting in ear,
baby crying, many power tools ·120 thunder, jet takeoff
at 200' ·130-140 firecracker, gunshot, powerful car speakers
·180 rocket launching According to the Noise Center,
musical toys measure over 110 decibels, comparable to many power
tools.
TEENS
With your teenagers, pay special attention. So many of the
things they love are not advisable:
Clubs and discos, 91 - 96 dBA + Dance floor, 85 - 100 dBA At
the bar, 90 dBA or more Personal stereo systems. 60 - 114 dBA
Rock concerts, 100 dBA or more average Car stereos, up to 154
dBA in the car!! Home stereo, 80 - 115 dBA
If you take your kids hunting or to the shooting range, take
the hearing protectors along. Firearms are all high and a single
exposure can cause permanent hearing loss. Examples, 12-guage
shotgun, 150-165 dB, shotgun, 163-172 dB, rifle, 143-170 dB.
Most firearms start at 100 dB and can go as high as 190 Db.
You may also assign your older child or teenage chores involving
power tools which require supervision for safety, including
hearing safety.
Also note than a firecracker can cause immediate damage.
RECREATION
Two other things children and teens like should be monitored.
Noise levels at video arcades can exceed 100 decibels (similar
to factory machinery), and computer games and stereo systems
can go as high as 135 dB (the level of a jackhammer), with car
stereos reaching up to 154 dB, and an action movie is generally
beyond 90 dB.
No one knows exactly what level damages a child's ears, but
the Noise Center's Rule of Thumb is: IF YOU HAVE TO SHOUT TO
BE HEARD THREE FEET AWAY, THE NOISE IS TOO LOUD AND IS DAMAGING
TO YOUR HEARING. Don't let your child become a statistic. According
to Dangerous Decibels, approximately 30 million Americans have
hearing loss, and 50 million have tinnitus, an early indicator.
According to a study done by Montgomery and Fujukawa in 1992,
"Over the last 10 years, the percentage of 2nd graders
with hearing loss has increased 2.8 times; hearing loss in 8th
graders has increased over 4 times."
Check with your child's pediatrician for specific information.
This is not medical advice.

Survey [Niskar, 2000]. Reported on DangerousDecibels.
WHAT CAN YOU DO?
1.Educate yourself about noise levels
2.Provide your child with peace and quiet
3.Make it clear you value peace and quiet
4.Counteract that "loud is cool"
5.Ask your local theater to lower decibel levels
6.Provide ear protection
7.Model good hearing protection
8.Include instruction the same way you do when you tell them
brushing their teeth twice a day prevents tooth decay
9.Turn down the volume of everything at home and tell your child
why you're doing it
