Earphones!
Earphones provide a very
personal and what may be
termed immersive listening
experience. Almost every
one of us owns them and it
comes at cheap prices. It’s
very soothing to hear music
with earphones.

3. 3
But are we thinking about
the side effects?

4. 4
• At 95 dB, damage will occur after four hours of exposure per day.
• At 100 dB, damage will occur after two hours of exposure per
day.
• At 105 dB, damage will occur after one hour of exposure per day.
• At 110 dB, damage will occur after 30 minutes of exposure per
day.
• At 115 dB, damage will occur after 15 minutes of exposure per
day.
• At 120+ dB, damage occurs almost immediately.
Most portable stereo music systems
produce sound in the range of 95-
108 dB and in excess of 115 dB!!!So can we imagine the danger?

Using earphones for a long period causes:
 Tinnitus-Noise in ear
 Hyperacusis-Sensitive ear
 Severe Ear Infection
 Loss of Hearing
 Affects Your brain
 Ear Pain
 Numb Ear
 Exposed to Radiation

6. 6
So, you can lose your hearing ability for listening
to music in high volumes for a long time.

7. 7
Earphones can cause Life Threatening Accidents!
When a driver wears headphones he or she may be unable to hear the
following:
 Car horns from other vehicle
 Emergency vehicle sirens
 Alarms for crosswalks
 Railroad crossing alarms
This decreased awareness and limited
hearing can make a driver cause an
accident that severely harms another
innocent driver.

8. 8
Some people are unaware while crossing roads and rail tracks.

9. 9
Here what we should do…
• Never Use Music Players at More Than 60% of The Maximum Volume.
• Do Not Use Your Music Player For More Than 60 Minutes A Day.
• Don’t Use Your Earphones in Loud Environments.
• Avoid Using In-ear Earphones.
• Use Noise-cancelling Headphones.
• Avoid Using Earphones While Driving or Crossing Roads or Rail Tracks.

Conclusion
Technology and gadgets are to make our lives
easy, but when used in the limit. We all must
know, How much is too much!
