Advances in Audiology and Hearing Aid Technology Presentation Transcript

  • 1. Advances in Audiology and Hearing Aid Technology …presented by: Dr. Thomas R. Goyne Aberdeen Audiology _______________________________ www.AberdeenAudiology.com www.DoctorTomGoyne.com
  • 2. What’s an Audiologist?
    • A professional, often with a doctoral degree (Au.D.), who is trained in the diagnosis and treatment of hearing and balance disorders.
    • Treatments include hearing aids, aural rehabilitation or counseling, and certain exercises for balance.
  • 3. Dr. Thomas R. Goyne
    • An eastern Pennsylvania native, Dr. Goyne earned degrees from James Madison University (B.S. and M.Ed.) and the University of Florida (Au.D.).
    • In addition to his duties at Aberdeen Audiology, Dr. Goyne also serves on the clinical faculty at the Pennsylvania Ear Institute.
  • 4. gj
    • A private audiology practice. Services include hearing diagnostics of both adults and pediatrics, hearing aid prescription and fitting/programming.
    • Offices located in Wayne, PA, just off of Sugartown Road. (610) 688-6003
  • 5. The Inner Workings
  • 6. The Inner Workings
  • 7. The Inner Workings
    • If the cochlea were stretched out, the sensory cells, nicknamed “hair cells”, would be visible under a microscope in rows.
    • Noise exposure, age, and drug interactions can cause the loss of these cells.
  • 8. Hearing Assessment
    • At Hear Well Again Centers , we employ and extensive battery of tests in order to gain as much information about a patient’s hearing and needs. [testing is covered by nearly all insurance plans]
      • Otoscopy : A thorough visual examination of the ear.
      • Traditional audiometry : Determining the softest sound a patient can hear.
      • Speech testing : Determines how well a patient can understand speech in quiet and in background noise.
      • Tympanometry : Measures how well the ear drum moves.
      • Otoacoustic emissions : Inner ear sensory cell integrity.
  • 9. The Essence of the Problem
    • “ I can hear just fine, but I can’t make out the words…”
    • A typical hearing loss filters out the consonants of speech [s,f,p,b,t, etc.] while allowing the vowels [a,e,i,o,u] to pass through.
  • 10. Hearing Is One Thing, Understanding is Another…
    • With a hearing loss:
      • “ _ill __e __illie_ _i_ __e Worl_ _erie_ _i_ _easo_?”
  • 11. Hearing Is One Thing, Understanding is Another…
    • With a hearing loss:
      • “ _ill __e __illie_ _i_ __e Worl_ _erie_ _i_ _easo_?”
    • Corrected hearing:
      • “ Will the Phillies win the World Series this season ?”
  • 12. This ain’t grandaddy’s hearing aid.
    • Today’s hearing aids are significantly better than what has been available in the past.
    • Through digital signal processing, hearing aids have become quite sophisticated while at the same time, they are often much more automatic for the user than ever before.
  • 13. Behind the Scenes
    • The best method for alleviating competing noise for hearing aid patients is for the hearing aid to have directional microphones. In many of today’s devices, the directionality is adaptive.
  • 14. Directional Mics Made Simple
    • A hearing aid with a directional microphone is analogous to a miner’s headlamp…
    • Just as the lamp sheds light to the front, the hearing aid will “illuminate” or amplify sounds in front of you, while sounds to the rear and sides are attenuated or “darkened”.
  • 15. But How Does It Know?
    • Nearly 100% of today’s hearing aids can be adjusted on a computer by an audiologist.
    • Patients can hear the changes made to the hearing aid while they are in their ears.
  • 16. How Does It Know?
  • 17. How Does It Know
  • 18. Remember…
    • … Today’s hearing aids, while more sophisticated,
    • are much easier
    • for patients to use than ever before.
  • 19. The Latest Trend
    • For decades, audiologists and hearing aid specialists spent countless hours attempting to relieve users of amplification of the sensation of feeling “plugged up” or “underwater” or “in a barrel”.
    • Today’s open-ear devices virtually eliminate that issue and have now become one of the most popular types of hearing aids dispensed today.
  • 20. The Latest Trend
    • Patient’s report greater comfort, more natural sound, and significantly greater reliability.
  • 21. Future Trends
    • One week away : Rechargeable hearing aids.
    • Six to 12 months away : Hearing aids incorporating “Blue Tooth” technology.
    • One to two years away : Artificial intelligence and data-learning.
