Sounds of Life
Hearing connects us with:
– Family
– Friends
– Sounds in our environment
– Music we love
When hearing loss is present it can
put limits on your life.

Hearing and Hearing Loss…
![Page 8: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/8.jpg)
How We Hear…
The ear is made up of 3 parts:
• Outer Ear
• Middle Ear
• Inner Ear
Each of these three parts has a
special function that allow us to hear.
![Page 9: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/9.jpg)
Outer Ear
Sound is:
• Picked up by the outer ear – pinna
• Sent down to ear canal to the eardrum
![Page 10: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/10.jpg)
Middle Ear
As sound is sent down the
canal to the eardrum• Sound vibrations cause the eardrum
to rock back and forth.• Three tiny bones in the middle ear
send the sound vibrations the inner ear.
![Page 11: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/11.jpg)
Inner Ear
The inner ear contains over 30,000 tiny hair cells
• Vibrations from the middle
ear cause hair cells to move.• Hair cells are connected
to the hearing nerve and
send the hearing signal to
the brain
![Page 12: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/12.jpg)
Three Types of Hearing Loss1. Conductive Hearing Loss
Sound is blocked in the outer or middle ear.
Causes:• Excessive earwax• Damaged eardrum• Ear infection or fluid in the
middle ear• Stiffness in the bones of the
middle ear (otosclerosis)
Solution:• Most often medically treated with high success• Hearing aids very successful if unable to treat medically
![Page 13: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/13.jpg)
Three Types of Hearing Loss2. Sensorineural Hearing Loss
Inner ear hair cells or hearing nerve is
damaged and cannot send complete signals to the brain.
Causes:
• Aging
• Noise Exposure
• Hereditary factors
Solutions:
• Cannot be corrected with medicine or surgery
• Hearing aids can be very helpful
![Page 14: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/14.jpg)
Three Types of Hearing Loss3. Mixed Hearing Loss
Both conductive and sensorineural hearing loss
occur simultaneously
Causes:
• Can be one or several causes
Solutions:
• May be possible to restore some
hearing with medicine or surgery
• Hearing aids can be very helpful
![Page 15: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/15.jpg)

Sensorineural Hearing Loss

Presbycusis: Hearing Loss due to Aging
![Page 23: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/23.jpg)
The Impact of Hearing Loss on Speech Understanding
• Most people with hearing loss have difficulty with high pitched sound like “s” “sh” “f” and “t”.
• For example:
• “eeee”
• “see” “she” “fee” “tee”
sounds all sound alike
• It is common for people with a hearing loss to say “I can hear but I can’t understand” because important sounds are missing.

When Hearing AidsAre the Solution
![Page 32: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/32.jpg)
Are All Hearing Aids the Same?
Hearing aids range in:
• Style and size
• Technology
• Flexibility
• Effectiveness within a noisy environment
All of the above factors are reflected in price.
![Page 33: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/33.jpg)
Size and Style
• In the Ear • In the Canal • Completely in the canal
• Receiver In the Ear • Behind the Ear
![Page 34: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/34.jpg)
Flexibility
Everyone's hearing needs are unique
• Degree and tones affected
• Tolerance to loud sounds
• Listening environments
Hearing aids can be customized to your hearing needs using a computer.
![Page 35: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/35.jpg)
One Hearing Aid or Two?
If there is hearing loss in both ears, you should wear two hearing aids. Why?
• Better sound sensitivity – “Stereo” quality
• Improved ability to locate sound
• Easier to understand speech in noise
• Risk of “auditory deprivation” is reduced
![Page 36: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/36.jpg)
Hearing in Noise
A normal auditory system can:
• Detect and focus on speech
• Tune out unwanted “noise”
• Automatically minimize
annoying sounds to enhance
speech
Hearing impairment disrupts these abilities.
![Page 37: Educational Seminar. 2 Hearing and Hearing Loss 3 Evaluating Your Hearing 4 Reconnecting to Your World 5 When Hearing Instruments are the Solution 6 Today’s.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649da25503460f94a8ec3c/html5/thumbnails/37.jpg)
