38 Multiple choice questions

  1. Click ABR
  2. - Reference equivalent threshold sound pressure levels

    - What SPL each transducer needs at each freq. to be calibrated to 0 dB HL
  3. • Do not require behavioral (voluntary) responses

    • Directly measures real-ear output levels across freqs.

    • Can make predictions based on ear canal levels for amplified speech across freqs.

    • Takes less time than behavioral measures

    • Tests at more "real-life" intensities

    • Realize the kid must still be calm; have several things to distract
  4. difference in output of HA between the real ear and 2-cc coupler. Comparison of exact same signal of the 2cc coupler and the signal measured in the canal
  5. Ensure meeting patient needs/targets

    • Aided SII

    • Functional Measurements
  6. -Aided SF speech
    • Age-appropriate material

    -Functional measurements, such as:
    • SIFTER, Pre-school SIFTER
    • Listening Inventory for Listening Difficulties
    • Parent's APHAB
    • Functional Auditory Performance Inventory
    • Meaningful Auditory Performance Integration Scale; Infant-Todder Meaningful Auditory Performance Integration Scale
    • PEACH, LittlEears
  7. -The only thing that checks for auditory neuropathy.

    - Clean waveform and easy to interpret.
  8. Speech stimuli
  9. - FM compatible battery door (HA is FM compatible or DAI)
    - Tamper proof (age dependent)
    - Pedi earhook
    - Water-resistant HAs
    - Flexibility of having on omni/directional
    - Turn off volume control buttons
  10. - Doesn't give you any lows

    - Clicks are based on the best threshold in 2000-4000 Hz.
  11. No because it's not ear specific; only getting one ear. Could potentially get too much lows or highs.
  12. • Confirming behavioral responses if child's developmental age is <6 months
    500 Hz; more freq. specific
    • Argument for slope of click-evoked wave V latency-intensity function tells configuration of the loss
  13. independent measures
  14. REAG
  15. DSL: children
    NAL: adults
  16. 2cc coupler SSPL90 +RECD
  17. dB eHL obtained + RETSPL + RECD = dB SPL
  18. To provide children with amplified speech that is consistently audible, comfortable, and undistorted across the frequency spectrum. Flexible in what intensity reference is used.
  19. • More helpful for counseling

    • Good cross-check
  20. No! Youngest is 3 months, dependent on how quickly services go.
  21. 2000-4000 Hz

    ABR clicks.

    Minimum Click at 500 Hz, and then try to get 2000 and 4000 Hz to continue to work on the fitting.
  22. neurologic status
  23. RECD and ear canal response
  24. - Binaural fittings unless contraindicated
    - Programmable aids
    - Minimum of 2 year warranty
    - Soft ear mold materials (silicone)
  25. • 500: 15-20 dB
    • All other freqs.: 10 dB
    • nHL - correction factor = eHL
  26. True!
  27. Ear canal length

    -Ear canal occluded volume

    -ME impedance

    -Earmold acoustics

    -Head & body diffraction effects
  28. BTEs
  29. Adults don't have growing ears. Fitting will continually change for children. Kids don't also have a base for language.
  30. - The HAs will think the tones are noise.

    - Never use Behavioral thresholds to fit HAs

    - Not taking ear canal acoustics into account

    - If testing at loud levels, compression could kick in
  31. Real ear to dial difference

    -Difference in SPL in ear vs. dial on the audiometer
  32. RECD, the bigger the RECD, the greater chance of oversimplification
  33. Test boxes
  34. BTE because compatibility for FM systems, they having growing ears (easier to switch out the ear molds), durable, and better retention.
  35. RECD
  36. adult size ear canal
  37. SII of <0.65 correlates w/ greater delays in vocabulary development for losses up to moderately severe
  38. Confirm behavioral responses with electrophysiology (ABR)
