How Noise Can Harm Your
Hearing
by: Jane Lake
The good news is that you don't have to lose your hearing as you age.
The bad news is, you will - unless you limit your exposure to high noise
levels. The most preventable cause of hearing loss is the cumulative
effect of noise. The following suggestions and decibel (dB) chart will
help you gauge your exposure to noise and reduce your risk of hearing
loss:
- Wear ear plugs when
operating noisy equipment (i.e. lawn mower, motorboat or power
tools).
- Set car, home and
portable stereos to below half volume. Beware of music levels in
exercise classes, concerts and bars.
- Look for a product
recommended for quiet operation when shopping for a fan, air
conditioner or other household appliance.
- Don't buy noisy toys.
Some toy musical instruments emit dangerous sound levels, while cap
guns and firecrackers, exploding near the ear, can damage hearing
even if you only hear them once.
- Any noise which makes
your ears ring, a condition called tinnitus, is too loud.
- Protect your ears if
you hunt or shoot guns. Acoustic trauma - immediate, severe and
persistent hearing loss - is directly linked to gunfire.
- If your workplace is
noisy, ensure that ear protectors are provided, and wear them.
- Make sure printers,
copiers and other noisy office machines aren't grouped together.
- Wear ear plugs at rock
concerts.
- Avoid places where you
cannot talk comfortably with another person who is three feet away.
- Wear ear protectors
for loud hobbies like snowmobiling or woodworking.
How Loud is Too Loud? Use
this Decibel Chart to Gauge Noise Level Effects
- Normal breathing, 10
dB - Just audible
- Quiet office,
refrigerator, 50 dB - Comfortable
- Vacuum cleaner, hair
dryer, inside a car, 70 dB - Intrusive, interferes with telephone
conversation
- Average city traffic,
alarm clock, 80 dB - Annoying, intrusive, interferes with
conversation
- Electric razor, many
industrial work places, 85 dB
Level at which hearing
damage (8 hours) begins
- Subway, motorcycle,
lawn mower, 90 dB - Very annoying
- Average portable cd
player set above half volume, 95 dB - Repeated exposure risks
permanent hearing loss
- Chain saw, subway
train, garbage truck, 100 dB - Damage after 15 minutes exposure
- Inboard motorboat,
power saw, highly amplified rock music, pneumatic drill, 110 dB
Regular exposure of 1
minute risks permanent hearing loss
- Thunderclap (nearby),
jet engine (at take off), very loud nightclub, 120 dB - Threshold of
pain
Shotgun firing, air-raid siren, 130 dB - May cause acoustic trauma

Noise pollution is
increasing, with city noise doubling every decade. However, by limiting
the noise that you and your children are exposed to, you can help
protect yourself, and them, from future hearing loss.
