  1. 1. Hearing Aids<br />Air conduction<br />Behind the ear (BTE)<br />In the ear (ITE)<br />In the canal (ITC/CIC)<br />Bone conduction<br />Traditional<br />Implantable (BAHA)<br />Electronic stimulation<br />Cochlear implant<br />
  2. 2. Hearing Aids<br />Air conduction<br />Behind the ear (BTE)<br />In the ear (ITE)<br />In the canal (ITC/CIC)<br />Bone conduction<br />Traditional<br />Implantable (BAHA)<br />Electronic stimulation<br />Cochlear implant<br />Most common<br />Few contraindications<br />
  3. 3. Hearing Aids<br />Air conduction<br />Behind the ear (BTE)<br />In the ear (ITE)<br />In the canal (ITC/CIC)<br />Bone conduction<br />Traditional<br />Implantable (BAHA)<br />Electronic stimulation<br />Cochlear implant<br />Most common<br />Few contraindications<br />Used for conductive loss<br />
  4. 4. Hearing Aids<br />Air conduction<br />Behind the ear (BTE)<br />In the ear (ITE)<br />In the canal (ITC/CIC)<br />Bone conduction<br />Traditional<br />Implantable (BAHA)<br />Electronic stimulation<br />Cochlear implant<br />Most common<br />Few contraindications<br />Used for conductive loss<br />Used for severe to profound loss<br />
  5. 5. Hearing Aid<br />Behind the ear<br />most common for children<br />Components<br />Battery<br />Earmold<br />Tubing<br />Earhook<br />Battery Door<br />Microphone<br />Processor/Amplifier<br />Receiver<br />
  6. 6. Hearing Aid<br />Troubleshooting<br />Battery<br />No sound<br />Replace battery<br />
  7. 7. Hearing Aid<br />Troubleshooting<br />Earmold<br />Blocked with cerumen<br />Pick out<br />Tubing<br />Blocked with moisture/cerumen<br />Blow out<br />
  8. 8. Hearing Aid<br />Troubleshooting<br />Earhook<br />Plugged with moisture<br />Blow out or replace<br />Battery Door<br />Broken?<br />Replace<br />
  9. 9. Hearing Aid<br />Troubleshooting<br />Microphone<br />Weak or no amplified sound<br />May hear buzzing or interference if put near computer screen or fluorescent light<br />Try cleaning microphone port with a brush<br />Otherwise send in<br />
  10. 10. Hearing Aid<br />Troubleshooting<br />Processor/Amplifier<br />Weak, distorted<br />Send in<br />Receiver<br />Distorted or no sound from hearing aid at all with earhook removed<br />Send in<br />
  11. 11. Hearing Aid Fitting<br />Pediatric considerations<br />Size<br />Compliance<br />Communication<br />
  12. 12. Hearing Aid Fitting<br />Size<br />Smaller ear canal volume<br />Higher sound pressure level<br />Importance of real ear measurements<br />Growth<br />Ear canal volume increases<br />Real-ear aided gain decreases<br />Earmold fits loosely<br />
  13. 13. Hearing Aid Fitting<br />Compliance<br />Hearing aid retention<br />Habituation schedule<br />Incentives<br />Volume control deactivation<br />
  14. 14. Hearing Aid Fitting<br />Communication<br />Daily listening checks<br />Familiarity with child’s typical response to sound<br />Training child to report issues<br />
  15. 15. Cochlear Implant<br />External processor<br />External coil<br />Internal coil<br />Electrode array<br />
  16. 16. Cochlear Implant<br />External processor<br />External coil<br />Internal coil<br />Electrode array<br />
  17. 17. Advanced Bionics Auria<br />
  18. 18. Advanced Bionics Auria<br />FireFly™ lights up to provide visual confirmation that the processor is communicating with the implant and the power source is operating. <br />When first on, it will flicker either 1or 2 times depending on which program is active.<br />It will illuminate a steady amber light if the system is functioning properly.<br />It will flicker rhythmically if the processor is not communicating with the internal implant.<br />It will not illuminate at all if the battery is depleted.<br />
  19. 19. Cochlear Nucleus 5<br />
  20. 20. Cochlear Implant<br />Pediatric considerations<br />Compliance<br />Retention<br />Habituation<br />Communication<br />Monitor child’s response to sound<br />Daily integrity checks<br />
