The flashcards below were created by user Wesleypjones on FreezingBlue Flashcards.

  1. Lyric/Deep fit extended wear
    • -analog processing/minimal fine tuning,¬†can only amplify signal
    • -best for adults
    • -moderate to severe loss
    • -device removed and replaced every 4 months
    • -expensive
    • -not suitable for small ear canals
  2. IIC invisible in the canal
    • -small so less features
    • -natural resonance is maintained
    • -mild to moderate hearing loss (not severe)
    • -removed at night
    • -less powerful and prone to wax build up
    • -prone to feedback,
  3. CIC completely in the canal
    • more powerful than a IIC, and better for people with smaller canals
    • -mild to moderate loss
    • -same cons as IIC
  4. ITC (In the Canal)
    • -fit mild to moderate
    • - same cons as CIC and IIC
    • -bigger battery
  5. half shell
    • good for someone with more moderate to severe hearing loss
    • -less occlusion¬†
    • -more features
    • -wax build up, feedback
  6. in the ear/half shell
    • -good for someone who needs more power or has oxygen or wears glasses
    • -up to severe losses
    • -lots of features
  7. BTE with ear mold
    • -most powerful HA
    • -compatible with FM
    • -more durable, can change earmold
    • -harder to localize sound
    • -best option for kids
  8. BTE with open fit
    • -less occlusion
    • -more prone to feedback
    • -can fall out easier than other options
    • -better for high frequency loss
  9. RITE receiver in the ear
    • -normal low freq with high freq loss
    • -more discrete
    • -less prone to feedback
    • -poor durability with receiver in ear canal and prone to wax build up
  10. what dictates style
    • severity of hearing loss
    • dexterity
    • personal preference
    • accessories needed
    • cognitive deficits
  11. Linear amplification
    all sounds are amplified a set amount regardless of the intensity-better for speech in quiet
  12. non-linear amplification
    • the amount the sound is amplified depends on the intensity of the incoming sound. Softer sounds are amplified more than louder sounds-does the same job as outer hair cells
    • -better for speech in noise
  13. sensorineural loss causes
    • -loss of clarity
    • -loss of sensitivity
    • -loss of temporal and spectral resolution
  14. Trouble shooting: feedback
    • -is there ear wax
    • -tube cracked or moisture in it
    • -fitting properly
    • -is it inserted properly in the ear
  15. Trouble shooting: no sound
    • -check battery and if the hearing aid is on
    • -is the end plugged with wax
    • -is the tube plugged with wax or moisture
    • -has the wire been kinked
  16. listening check: check for
    ambient noise, interference and static, intermittent signal, distorted speech/sound quality, Ling 6, low battery signal
