  1. 1. HEARING AID 101 Session 1 www.fixmyhearing.com [email_address] Welcome to…
  2. 2. Introductions… <ul><li>Any new hearing aid users?? </li></ul><ul><li>Reasons for getting hearing aids?? </li></ul>
  3. 3. Outline for Session 1: <ul><li>HOW WE HEAR </li></ul><ul><li>REALISTIC EXPECTATIONS OF HEARING AIDS </li></ul><ul><li>INTERPRETING HEARING LOSS </li></ul><ul><li>ADJUSTING TO HEARING AIDS </li></ul><ul><li>DO’s/DON’Ts OF HEARING AIDS & BATTERIES </li></ul><ul><li>TROUBLESHOOTING TIPS </li></ul>
  4. 4. HOW WE HEAR…
  5. 5. How we Hear… <ul><li>We have 3 major parts to the ear that work together to send sound to the brain where it is interpreted </li></ul>
  6. 6. Outer Ear <ul><li>Job is to collect sound waves and funnel them along the ear canal to the eardrum </li></ul>
  7. 7. Middle Ear <ul><li>When the sound waves hit the eardrum, they cause the eardrum to vibrate </li></ul><ul><li>The vibration causes the 3 bones of the middle ear to move </li></ul><ul><li>The middle ear space is a sealed, air-filled cavity. The Eustachian Tube connects the middle ear to the back of the nose. This tube equalizes pressure changes to the outside air. </li></ul>
  8. 8. Inner Ear <ul><li>The movement of the 3 middle ear bones sets the fluid of the inner ear into motion </li></ul><ul><li>Fluid movement shears thousands of microscopic hair cells </li></ul><ul><li>Shearing of a hair cell stimulates the auditory nerve </li></ul><ul><li>The auditory nerve sends </li></ul><ul><li>an impulse to the brain </li></ul><ul><li>where the signal is </li></ul><ul><li>interpreted </li></ul><ul><li>The inner ear also houses the balance organs! </li></ul>
  9. 9. In a nutshell… 1. Fluid movement shears hair cells… 2. The sheared hair cells activate the auditory nerve – telling it to send a signal… 3. The signal reaches the auditory center in the brain where it is interpreted! Cochlea Auditory Nerve Brain
  10. 10. A view from the front…
  11. 11. How DOES hearing loss occur? <ul><li>A hearing loss can result from disruption of normal function ANYWHERE along the auditory system </li></ul>
  12. 12. 3 types of hearing loss can occur… <ul><li>CONDUCTIVE HEARING LOSS : A hearing loss resulting from disorders of the OUTER &/or MIDDLE EARS </li></ul><ul><ul><li>Sound is prevented from entering a normal functioning inner ear </li></ul></ul>
  13. 13. Conductive Hearing Loss <ul><li>What causes this “blockage” of sound? </li></ul><ul><li>Middle ear infection </li></ul><ul><li>Fluid in the middle ear (with no infection) </li></ul><ul><li>Ruptured eardrum </li></ul><ul><li>Unhinging of the middle ear bones </li></ul><ul><li>Stiffening of the middle ear bones (otosclerosis) </li></ul><ul><li>Tumor in the middle ear space </li></ul><ul><li>Wax build-up </li></ul>
  14. 14. Some examples of conductive losses… <ul><li>Can usually be treated medically or surgically </li></ul>
  15. 15. Types of loss (continued)… <ul><li>2. SENSORINEURAL HEARING LOSS : A hearing loss resulting from disorders or damage to the inner ear (cochlea) &/or the auditory nerve. Commonly referred to as “nerve loss”. </li></ul>
  16. 16. What causes a sensorineural hearing loss?? <ul><li>Noise exposure </li></ul><ul><li>Advancing Age </li></ul><ul><li>Hereditary </li></ul><ul><li>Ototoxic medications </li></ul><ul><li>Syndromes/Disorders </li></ul><ul><li>Infections </li></ul><ul><li>Head Trauma </li></ul><ul><li>Tumor on auditory nerve </li></ul><ul><li>… or a COMBINATION of the above </li></ul>
  17. 17. Characteristics of Sensorineural Hearing Loss: <ul><li>Usually permanent </li></ul><ul><li>Can continue to deteriorate </li></ul><ul><li>Usually NOT treatable by medication/surgery </li></ul><ul><li>Hearing aids are the solution! </li></ul>
  18. 19. Types of loss (continued)… <ul><li>3. MIXED HEARING LOSS : A hearing loss that consists of BOTH a conductive and a sensorineural component </li></ul><ul><li>Example: A sensorineural hearing loss from noise exposure + a conductive hearing loss from a perforated eardrum = MIXED HEARING LOSS </li></ul>
  19. 20. “ I can hear but I can’t understand ” <ul><li>If the problem is with DETECTING sounds, making the sounds louder will make them clear… this is true for the person with a Conductive hearing loss (remember, they have a normal inner ear) </li></ul><ul><li>LOUDNESS </li></ul><ul><li>LOUDNESS </li></ul><ul><li>LOUDNESS </li></ul><ul><li>LOUDNESS </li></ul><ul><li>LOUDNESS </li></ul>
  20. 21. “ I can hear but I can’t understand ” <ul><li>If the problem is with understanding, however, then making sounds louder will NOT provide normal, clear speech. This is the case with Sensorineural hearing loss . </li></ul><ul><li>CLEARNESS </li></ul><ul><li>CLEARNESS </li></ul><ul><li>CLEARNESS </li></ul><ul><li>CLEARNESS </li></ul>
  21. 22. WHY? <ul><li>Damage to the inner ear/nerve (i.e. loss of hair cells) creates a DISTORTED signal that is sent to the brain. </li></ul><ul><li>This is why individuals with sensorineural hearing loss need to know that hearing aids do not restore normal hearing </li></ul><ul><li>Having REALISTIC EXPECTATIONS of hearing aids is important! </li></ul>
  22. 23. Realistic Expectations… <ul><li>Your voice & the voices of others may sound different </li></ul><ul><li>Background noise will inevitably get amplified in addition to speech, therefore speech may be difficult to understand in noise </li></ul><ul><li>You may have difficulty understanding speech (in general) depending on the severity of your hearing loss, the speaker, and the environment </li></ul>
  23. 24. Realistic Expectations …(continued) <ul><li>It will still be difficult to understand people talking from another room </li></ul><ul><li>Hearing aids are less helpful in rooms with hard floors & walls & no carpet or drapes </li></ul><ul><li>Hearing aids should be a comfortable fit </li></ul><ul><li>No feedback at a comfortable volume setting </li></ul><ul><li>Hearing aids should make soft sounds audible , normal sounds comfortable , and loud sounds tolerable </li></ul><ul><li>Even people with normal hearing find many listening situations difficult! </li></ul>
  24. 25. Do you know how to read your hearing loss?? <ul><li>Sound is made up of pitch & loudness </li></ul><ul><li>Unwanted sound is referred to as “NOISE” </li></ul>
  25. 26. A moderate high-frequency sensorineural hearing loss… NORMAL HEARING = RIGHT EAR = LEFT EAR
  26. 27. Degrees of Hearing Loss: <ul><li>Mild loss : Difficulty with faint speech & speech in “less than ideal” situations </li></ul><ul><li>Moderate loss : Frequent difficulty with normal speech (even in “ideal” situations”); repetition is often necessary; listening is a strain </li></ul><ul><li>Severe loss : May hear loud voice approximately 1 ft. from ear; may identify environmental sounds; may distinguish vowels of speech </li></ul><ul><li>Profound loss : Usually cannot understand amplified speech; hearing is not typically the primary mode of communication </li></ul>
  27. 30. Adjusting to your Hearing Aids… <ul><li>Quiet living room. One person talks about familiar things at different places in the room. </li></ul><ul><li>Go to kitchen. Run the water. </li></ul><ul><li>Radio/TV in a quiet room. Have a person with normal hearing adjust the volume. Begin with the news. </li></ul><ul><li>Wear aids at quiet dinner table. </li></ul><ul><li>Conversation in quiet room with 2…3…4 other people. </li></ul><ul><li>Outside (quiet place). Listen to wind noise. </li></ul><ul><li>Walk along street (quiet neighborhood). </li></ul><ul><li>Church, lectures, play. Sit close to speakers first. Later, try listening from a distance. </li></ul><ul><li>Driving. Listen to background noises. Open the window. </li></ul><ul><li>Shopping trip. </li></ul><ul><li>Party or room where several people are talking. </li></ul>Easier Harder
  28. 31. Above all… <ul><li>BE PATIENT! </li></ul><ul><li>Through time, noise and meaning will begin to sort themselves out </li></ul><ul><li>The more often you wear your hearing aids, the quicker this “sorting out” process will occur </li></ul><ul><li>THE BRAIN HAS TO HEAR WHAT THE BRAIN DOESN’T WANT TO HEAR IN ORDER TO KNOW IT DOESN’T WANT TO HEAR IT!! </li></ul>
