  28. List disadvantages of Click ABR
  29. Speech mapping can be done through____
  30. What is the GOAL for DSL?
  31. ABR Tone Burst
  32. Who do you use DSL and NAL for?
  33. Correction Factors
  34. Differences in RECD
  35. List the cons for aided sound field measures.
  36. Can you base binaural HA fitting on sound field MRL?
  37. Validation
  38. List the pros for aided sound field measures.
  1. a Speech stimuli
  2. b 2cc coupler SSPL90 +RECD
  3. c SII of <0.65 correlates w/ greater delays in vocabulary development for losses up to moderately severe
  4. d Ensure meeting patient needs/targets

    • Aided SII

    • Functional Measurements
  5. e No because it's not ear specific; only getting one ear. Could potentially get too much lows or highs.
  6. f • 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
  7. g independent measures
  8. h • More helpful for counseling

    • Good cross-check
  9. i -The only thing that checks for auditory neuropathy.

    - Clean waveform and easy to interpret.
  10. j • 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
  11. k - Binaural fittings unless contraindicated
    - Programmable aids
    - Minimum of 2 year warranty
    - Soft ear mold materials (silicone)
  12. l dB eHL obtained + RETSPL + RECD = dB SPL
  13. m RECD and ear canal response
  14. n Adults don't have growing ears. Fitting will continually change for children. Kids don't also have a base for language.
  15. o DSL: children
    NAL: adults
  16. p - 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
  17. q RECD
  18. r - Reference equivalent threshold sound pressure levels

    - What SPL each transducer needs at each freq. to be calibrated to 0 dB HL
  19. s No! Youngest is 3 months, dependent on how quickly services go.
  20. t RECD, the bigger the RECD, the greater chance of oversimplification
  21. u Test boxes
  22. v neurologic status
  23. w - Doesn't give you any lows

    - Clicks are based on the best threshold in 2000-4000 Hz.
  24. x -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
  25. y • 500: 15-20 dB
    • All other freqs.: 10 dB
    • nHL - correction factor = eHL
  26. z BTE because compatibility for FM systems, they having growing ears (easier to switch out the ear molds), durable, and better retention.
  27. aa To provide children with amplified speech that is consistently audible, comfortable, and undistorted across the frequency spectrum. Flexible in what intensity reference is used.
  28. ab True!
  29. ac 2000-4000 Hz
