PHEOCS INVESTIGATION
OF HEARING DAMAGE
By Matt Krause and Payton Claybaugh
PHEOCS Investigation
PHEOCS Intro
Parents often say that kids listen to their music to loudly. Well
we thought that it was time to test the theory and see if it was
true. To test this theory we used a Vernier Lab Quest and a
Vernier Sound Sensor. By testing a few subjects that are kids
ranging from 13-14 years old we found some information that
could prove the theory right or wrong, here is the
presentation showing you the information we found and
explaining how we did so.
Introduction
PHEOCS Background Information
Almost everybody you talk to is aware
that they should be cautious about the
level of music they listen to, but not many
change the levels they listen to music at.
Everybody is susceptible to have hearing
loss. It is like having vision loss, and
being deaf to being blind. 1 out of 3
babies have hearing loss so it starts at a
young age so you have to be very
cautious for yourself and others. You can
have hearing loss after listening to a
sound at 85 decibels or higher over a
period of time. A sound under 75 decibels
is unlikely to cause hearing loss if
listened to for a short period of time. The
highest decibel level possible of reaching
is 194 decibels.
Background
PHEOCS Questions and Answers

The decibel level is 80 DB.
What is the decibel level of a subway train at 200
feet?
The decibel level is 95 DB.

PHEOCS Questions and Answers
What is the decibel level at which pain begins?
The decibel level is 120 DB.
What is the decibel level of a 12 Gauge Shotgun
blast?
The decibel level is 165 DB.
What is the decibel level in which hearing tissue
dies?
The decibel level is 180 DB.
What is the noise level that earphones or
headphones can reach?
The decibel level is 100+ DB.
PHEOCS Questions and Answers
Nerve cells that carry electrical signals from the
ears to the brain have what type of coating and
what does it do?
Myelin sheath coating helps electrical signals travel
along the cell.
What does exposure to loud noises over 110
decibels do to nerve cells?
Loud noises over 110 decibels can strip cells from
their coating.
PHEOCS Questions and Answers
What are 3 signs of potential hearing loss?
-Three signs of potential hearing loss are difficulty
understanding speech, ringing in ears, or muffled
noises.
What are 4 recommendations for using ear buds
or headphones?
-Four recommendations when using ear buds or
headphones are limit your listening, don’t use max
volume, only use 70% of volume possible, and if you
can don’t use ear buds or headphones.
What happens to people who attend a rock
concert for longer than an hour?
- These people can suffer hearing damage that can be
permanent.
PHEOCS Our live expert
Our local expert that we contacted is Stephanie Long from ABC Audiology. This is
some of the information that she shared with us to answer some of our questions.
Audiologists help everyone from new born babies to very old people with hearing
loss. Most people don’t know that even tiny babies can have a hearing loss. In fact
between 1 and 3 babies born have some degree of hearing loss. Sound is measured
in units called decibels. On the decibel scale, an increase of 10 means that a sound
is 10 times more intense, or powerful. To your ears, it sounds twice as loud. The
humming of a refrigerator is 45 decibels, normal conversation is approximately 60
decibels, and the noise from heavy city traffic can reach 85 decibels. Sources of
noise that can cause NIHL (noise induced hearing loss) include motorcycles,
firecrackers, and small firearms, all emitting sounds from 120 to 150 decibels. Long
or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The
louder the sound, the shorter the time period before NIHL can occur. Sounds of less
than 75 decibels, even after long exposure, are unlikely to cause hearing loss.

PHEOCS Conclusions
Only one of our test subjects would have potential hearing loss, but it would be after 8 hours of listening to a sound at
the same decibel level. The other three subjects that we tested do not have any potential of hearing loss according to the decibel levels in our tests. We discovered that only one
of our test subjects had hearing loss. We figured out that the kids here are doing a good job of listening to music
responsibly and at an appropriate volume. That our test of decibel level test may be slightly louder due to the
background noise. What we could do next time is that we could test a few more people to figure out their hearing loss
potential damage.
Conclusion
PHEOCS Conclusions
Because we thought that one of our friend listened to her music to loud so we wanted to know if she
had hearing problems and we figured out that when she was younger she went to see an audiologist we contacted that audiologist because she helped my friend with her problems. So we used this to help me understand someone better and how much
better it would be if we helped her along the way.
Why We Did This
PHEOCS Conclusions
Because everyone has hearing damage if you are deaf you had damage because you can’t hear I wanted to study the rate of hearing damage of
teenagers and figure out if teenagers have more hearing loss than the rest of us. People said that sticks and stones may break my bones but words
will never hurt me. I figured out that that’s not true words can hurt you by damaging your hearing. By studying the rate of hearing you can predict your
gradual hearing loss. Thus doing so you can your life now for the benefits of later on.
How This Is Useful
PHEOCS Observations
What We Observed Everyone that we tested was willing and ready to find out how they might be damaging their ears. And that due to
background noise the tests might be louder. Also that all of our test subjects had over ear headphones not ear buds.
Everyone’s graph showed that their music volume level was over the talking level of 60 db. We didn’t test kids that might listen to music louder than these four subjects, and we didn’t
test all kinds of music. Also we observed that the subjects listen to music for a long period of music per day.
