Can You Hear Me Now? Hearing Aids: What You Need to Know Presentation Transcript

  • 1. Can You Hear Me Now? Stephanie K. Born, AuD Springfield Clinic Audiology
  • 2.
    • Audiologist- can prevent, identify, evaluate, and treat hearing disorders.
    • Audiologists also assess balance disorders.
  • 3. Hearing Loss Statistics
    • 36 million people in the United States have hearing loss.
    • It is present in all ages.
  • 4.
    • Hearing Loss is just another chapter
    • in your life.
    • However, do not let it define you.
    • You hearing loss is more noticeable than hearing aids.
  • 5. Your Job
    • Now, before we get started….if you have a hearing loss, you MUST have a sense of humor!!
    • You miss things and hear strange things that people didn’t really say.
    • You have to be able to laugh at it sometimes or it will drive you crazy!
  • 6. Anatomy of the Ear
    • Outer ear- pinna and external auditory meatus (ear canal)
    • Middle ear- tympanic membrane (eardrum) and middle ear ossicles (bones)
    • Inner ear- cochlea and vestibule (balance system)
    • (Discuss hair cells)

  • 7. Inner Ear Cochlea
    • The inner ear cochlea contains hair cells.
    • These hair cells stimulate the acoustic nerve by sending electrical signals to the nerve.
    • The sound is then processed in the brain.

  • 8. Anatomy of the Ear
    • Virtual Tour
    • Better Hearing Institute
  • 9. Types of Hearing Loss
    • Conductive hearing loss- Hearing loss due to a pathology in the OUTER or MIDDLE EAR .
    • Ear infection
    • Wax accumulation
    • Otosclerosis
    • Tympanic membrane (eardrum) perforation
    • Malformation of the outer or middle ear
    • (Note: There is no damage to the inner ear)
  • 10. Sensorineural Hearing Loss
    • Sensorineural Hearing Loss- Hearing loss due to a pathology in the INNER EAR .
    • Occurs when there is damage to the cochlear hair cells or auditory nerve.
    • Noise exposure
    • Presbycusis (age related)
    • Medication- chemotherapy, aminoglycoside antibiotics, etc.
    • Virus
    • Acoustic trauma (blast)
    • Genetics
    • Autoimmune
    • Meniere’s disease
  • 11. Cochlear Hair Cell Damage
  • 12. Sensorineural hearing loss
    • Sensorineural hearing loss is the most common hearing loss in adults.
    • The damage to the inner ear hair cells can also cause distortion of sound.
    • This causes speech to be unclear, even when sound is amplified.
    • (That is why hearing aids can increase volume, but cannot make
    • speech clearer.)
  • 13. Sensorineural hearing loss
    • Damaged hair cells become permanently damaged in the inner ear.
    • These hair cells are unable to regain function.
    • *There are current studies to regrow hair cells on chinchillas.
  • 14. Audiogram

  • 15. What can hearing aids do?
    • Hearing aids are programmed specifically for your hearing loss.
    • Hearing aids do not cure hearing loss.
    • Hearing aids are an aid and will HELP improve communication.
    • Limitations:
    • They will make sound louder, but CANNOT make it clearer.
    • *They can reduce background noise, but CANNOT eliminate it.*
  • 16. Hearing Aids
    • Before receiving hearing aids the patient will need:
    • 1) Audiological evaluation to determine
        • -Is there a hearing loss?
        • -Type of hearing loss
        • -Severity of hearing loss
        • -Word understanding ability (%)
        • -Is the patient a hearing aid candidate?
    • 2) Medical clearance from physician.
    • 3) Hearing aid consultation to determine best
    • hearing aids for pt.
  • 17. Hearing Aid Choices
    • Major Things You Have to Decide
    • 1. One hearing aid or two?
    • 2. What size or style of hearing aid?
    • 3. What features and price level will I need to best address your problem areas?
    • Some will affect the cost….
  • 18. One or Two Hearing Aids?
    • Advantages of two hearing aids
    • 1. Ability to hear to the left and right
    • 2. Ability to localize where sound is
    • 3. Sound clarity is better
    • 4. Understand better in noisy environments
    • 5. Most say “it’s easier to hear” with two
    • hearing aids
  • 19. One Hearing Aid or Two?
    • When Is One Hearing Aid Enough?
    • 1. Hearing loss in one ear
    • 2. When finances are a concern
  • 20. Style and Size of the Hearing Aids
    • Hearing aids come in 4 basic sizes
    • Which size is best for you depends upon:
    • 1. Size and shape of your ear
    • 2. Your hearing test results
    • 3. What features you want in the hearing aids to address your problem areas
    • 4. Your ability to put the aid in your ear.

  • 26. What Type of Circuitry?
    • Hearing aids can be made with different circuitry.
    • Basic circuits to advanced circuits (computer chip inside the aid)
    • Prices vary based on what features and options are present in the hearing aid circuit .
    • What’s important is to pick the features and options you need in a PRICE RANGE FOR YOU.
  • 27. What Are the “Special Features” and Options?
    • How precisely the hearing aid can be adjusted to your hearing levels
    • Automatic regulation of volume levels
    • Automatic adjustment for different listening environments
    • Noise block processing
    • Wind block technology
    • Whistle block technology
    • Echoblock technology
    • Duo-phone (hearing phone signal in both ears)
  • 28. What Features and Price Range Are Appealing to You?
    • Decide this and I will recommend which hearing aids should perform well for you in the size you want in your price range.
    • We work with 3 different companies, so I will choose a company and a specific hearing aid model that can best meet your requirements.
  • 29. Decisions…….
    • 1. One or Two Hearing Aids?
    • 2. Size/Style of Hearing Aid?
    • (Note: there may be compromises on size and features)
    • 3. What Features and Price Range?
  • 30. Where Do We Go From Here?
    • Take impressions of your ears (if needed)
    • Audiologist orders the hearing aids
    • You will return in 2 weeks for hearing aid fitting.
    • Begin 60-day trial period. Aids may be adjusted during office visit
    • during and after trial period.
    • Return in 2 weeks for hearing aid follow-up.
    • Begin the course “Be the Boss of my Hearing Loss”
  • 31.
    • Important…
    • Wear the hearing aids all day (except during water activities or bedtime)
    • The more you wear the hearing aids, the faster you will adjust.
    • The brain has to re-adjust to the new sounds.
  • 32. Helpful Hearing Aid Expectations
    • I have just begun the process of adjusting to my hearing loss and the
    • use of hearing aids.
    • 2) My own voice may sound different when I am wearing my hearing aids.
    • I may have a new awareness of footsteps, door closings, newspaper rustling, and so forth.
    • Listening when background noise is present will still be challenging.
    • My hearing aids are only one part of the services my audiologist supplies.
    • I will benefit most from amplification if I use speech reading and positive listening strategies along with it (e.g., I should not judge the effectiveness of hearing aids by asking people to cover their mouths when they speak).
    • From Mormer and Palmer in Counseling for Hearing Aid Fittings (edited by Sweetow, Singular Press, 1999).
  • 33. Bluetooth Technology
    • Wireless
    • Can listen to cell phone, TV, and MP3 player
    • Most companies have Bluetooth technology
    • Photo retrieved from: http://www.hearingaidresource.com/v/vspfiles/photos/ICOM-2T.jpg
  • 34. Expectations from Hearing Aids
    • Expect improved hearing, Not normal hearing
    • Prepare to be patient, it takes time to adjust to hearing aids and hearing sounds again
    • Anxiety and nervousness are fine, but be POSITIVE. 
  • 35.
    • Remember…
    • We are limited by our own auditory system.
    • Damage to inner ear hair cells
    • Distortion of sound
  • 36. Expectations
    • Know what hearing aids CAN and CANNOT do.
    • They are an aid. They cannot listen for you.
  • 37.
    • It’s Not All About Hearing!
    • Hearing:
    • -the capacity to hear
    • Listening:
    • -to make an effort to hear something
    • -to pay attention
  • 38.
    • Hearing aid will help you hear
    • You must be the one to listen

    • Up to 90% of people with tinnitus have hearing loss.
    • American Tinnitus Association
  • 49. Causes of Tinnitus
    • Excessive noise exposure (damaged hair cells)
    • Hearing loss (damaged hair cells)
    • Ototoxic medications (damaged hair cells)
    • Aspirin
    • Jaw misalignment (contraction of various muscles)
    • Cardiovascular disease (hypertension, etc)
    • Other
    • American Tinnitus Association
