Is Too Much Noise a Serious Problem?
Noise is probably one of the most common hazards in construction. But it often goes unrecognized because hearing loss creeps up on you. It doesn't happen all at once.
When you are exposed to too much noise, you can lose your hearing. You can also lose your life. On the job:
- Noise can distract you. You may not hear warnings.
- Noise damages the nerves in the inner ear. The nerves cannot be repaired.
After 15 to 20 years in the trade:
- You may suffer permanent hearing loss.
- You may suffer constant ringing (tinnitus).
Some of the most common noise sources in road construction are:
- heavy equipment,
- pile driving,
- pavement breakers,
- compressors,
- other noise sources.

Notes:
Ask trainees: Do you know any
co-workers with hearing loss?
Family members? Grandparents?
Hearing experts say that our ears
have a finite lifetime capacity for
noise exposure. Even lower levels
of noise use up this capacity.
Exposure to higher levels of noise
for continuous periods uses up
your lifetime capacity too soon.
After years of too much noise,
the nerve cells in the inner ear
die. You slowly loose the ability
to hear and understand speech.
Then suddenly you realize you
are hearing impaired.
Ask trainees: What are other noise
sources? Examples: traffic, compactors,
and milling machines.
Discuss non-occupational noise
exposures and the need to protect
from them as well (lawn mowers,
rock concerts, headphones,
motorcycles).
Could Road Work Be Less Noisy?
Yes. There are efforts being made by engineers, manufacturers, and contractors to make road construction more quiet. Noise levels can be reduced by:
- buying/renting less noisy equipment,
- keeping equipment well maintained,
- trying to isolate noisy equipment,
- keeping equipment well maintained, and
- using sound barriers around equipment.
How Do We Protect Our Hearing Now?
Wear hearing protectors. If you must shout to talk with someone 3 feet away, you need protection from noise:
- Use hearing protectors provided by your employer.
- Notify employer if proper hearing protection is not available.
- Make sure hearing protection fits and is comfortable.
- Follow instructions for proper hearing protection use.
- Get a baseline hearing test. Then test about once a year so you'll know your hearing protection is working.

Notes:
DEMONSTRATION:
Use a sound level meter (an
inexpensive meter can be purchased
from Radio Shack for
about $35) to show trainees how
it measures sound levels. Use it
to measure non-occupational
noise sources.
What are some early signs of
hearing loss? Have you ever driven
home with the car radio on
and when you started it up the
next morning it blasts in your
face? You probably experienced
some temporary hearing loss that
previous day. Or do you have to
turn up the TV to listen and your
family complains that it's too loud? Or do you have a hard time hearing conversation in a noisy room or on the job site? If so, these may be early signs of hearing loss.
Hearing loss often comes on gradually and unnoticed. That's why hearing tests are so important.
