1
Noise and You
  • (click on megaphones to hear sound)
  • JOAN FITCH RN/B.S.N

2
Why worry about noise?
  • Of all the pollution concerns
  • Air,water,land, and noise noise pollution is the
    one that has the potential for the most damage to
    humans and wildlife.
  • It is a hidden health hazard that impacts our
    physical, psychological and intellectual well
    being.
  • Our ears never shut down, even while we are
    sleeping, so the input is constant.

3
Noise Pollution
  • Noise pollution has a broad effect.
  • It can excite us
  • Warn us of danger
  • Soothe us
  • Inspire us
  • Keep us in touch with our surroundings.
  • And, harm our well being.

4
Noise is Everywhere
5
Hearing
  • Our ability to hear is one of our great senses
    that connects us with the world around us.
  • Without it, the world becomes a lonely,
    frightening place.

6
Our Magical Ears
7
Those Handles on Our Heads
  • Our ears arent there for decoration!
  • They are amazing neurotransmitters that gather
    and process sound, sending the input off to our
    brain where fascinating things happen.

8
The Ear and Our Brain
  • Our brain processes the sound waves received via
    our ears and makes determinations that effect
    speech, balance, and hearing.
  • Excess stimulation from sound can overload our
    nervous system resulting in many negative health
    symptoms.

9
What does our ear drum do?
  • Sound waves are collected by our ear canal and
    passed to the ear drum, which vibrates. The
    sound waves are then picked up by fluid in the
    inner ear and passed to the inner ear structures
    where the acoustic nerve connects to the brain.

10
The Mighty Decibel
  • Decibels measure the intensity of sound.
  • Hearing loss can occur from a single exposure to
    a loud noise or from repeated exposures.
  • The Environmental Protection Agency has set a
    standard of 70 db in a 24 hour period as safe.

11
The Numbers
  • Stereo - 90 db
  • bagpipes - 90-110 db
  • power saw - 100 db
  • fire cracker - 115-120 db
  • rock concert - 120 db
  • gunshot/train/jet -
  • 150 db
  • Rustling leaves- 10db
  • whisper - 30 db
  • normal speech - 60 db
  • television - 70 db
  • traffic - 75-80 db
  • blow dryer - 85 db
  • noisy hall - 85 db
  • classroom - 85 db

12
Physical Effects
  • Examples hearing loss, digestive disorders,
    birth defects, arthritis, cancer, heart disease,
    fatigue, headaches, asthma, hypertension,
    insomnia, sexual dysfunction, altered immune
    system.

13
Psychological Effects
  • Examples depression, anger, aggression, anxiety,
    increased violence, alcohol and drug use,
    fatigue, increase in suicide, decreased social
    skills, personality disorders

14
Communicative Effects
  • Examples decreased learning capacity, memory
    loss, poor language skills, decreased speech
    development, decreased academic performance,
    decreased cognitive ability

15
How much is too much?
  • Damage to health begins at 75 db.
  • Hearing damage begins at 90 db and can be
    permanent with one exposure of 120 db or more.
  • The average decibel levels at Montpelier High
    School are 70-86 where damage to physical,
    psychological and communicative health begins.

16
Music To Your Ears?
  • As a bagpiper I am acutely aware of the impact of
    noise on my well being. The average bagpipe
    generates 90-110 db.
  • It is important in any of our health arenas that
    we make deliberate choices about how to protect
    ourselves.

17
Shhhhhh
  • How can we stop the constant bombardment to our
    ears and protect our over all health?

18
Stopping the Noise
  • It cannot be done!
  • Even during sleep our ears are absorbing sound
    waves that are then processed by our brain.
  • What we can do is seek practical ways to diminish
    the noise OR protect our ears from receiving too
    much damaging input, i.e. decibels.

19
Know Thyself
  • Respecting sounds and how they can impact your
    health involves knowing yourself. We all have
    different thresholds of what we can handle.
  • What kinds of sounds stimulate you, soothe you,
    irritate you?
  • Do you find you have ringing in your ears after
    certain sound exposures?
  • Is there a family history of hearing loss?

20
So, Now What?
  • How do you balance what you enjoy with what is
    healthy?

21
Controlling the noise in your life is not
hopeless, but does require determination on your
part to respect and alter the level of noise.
  • Carpeting, pictures and plants will absorb sound.
  • Increase trees and shrubs around property.
  • Be aware of your surroundings and do whatever you
    can to reduce the noise level.
  • Find quiet time daily.
  • Limit your time in a noisy environment
  • Wear ear plugs in very loud places. Filtered ear
    plugs, such as Sonic II can be purchased in any
    music or gun shop. They reduce the damaging
    decibels, whereas foam plugs will muffle sound
    but still allow too high a decibel range to enter
    your ears.
