    Auditory Neuropathy/dys-synchrony
  34. T or F
    AN/AD is missed during a OAE only screening
    True

  50. When testing younger children, it is noted that a ___________ frequency range will catch their attention sooner.
    broader
  51. What is the danger of using a broad frequency range stimulus?

  53. BOA (Behavioral Observation Audiometry) is used during the first ____________ to ________ months of age. Uses ______ clinicians to direct and test the child. Observes the _____ and ______ movements of children when responding to sound

  54. T or F
    On BOA's you can use noise makers that are calibrated? This works on the childs ___________ but does little to specify the configuration of the hearing loss due to lack of _____________ __________.
    False, you can use ones that are NOT calibrated.

    instrument calibration
  55. Sound Field Audiometry process:
    • 1. child placed in sound suite wth 2 calibrated speakers for testing

    • 3. The is of BOA is advantageous due to the calibration of the sound source
    • 4. the use of voice, pure tones,and noise are used to obtain responses.
  56. VRA stands for
    Visual Reinforcement Audiometry
  57. (VRA) the use of sound field audiometry is still employed, but now with __________ reinforcement to obtain responses.
    Visual
  58. (VRA) A stimulus is played thorugh one of the speakers and a _________ reinforcement is used to reinforce the child's response.
