What is CPA?
Conditioned Play Audiometry
43
What is Behavioral Observation Audiometry?
Audiologist watches child for behavioral change Shows lowest level of responsiveness not hearing threshold (Some babies may react to 20 dB HL sound levels and others will not react until 60 dB HL) Can be highly subjective: i.e. observers expectations can basis outcome
44
What are the two categories for Responses to Sound?
REFLEXIVE (Startle, Limb jerks, Eye blinks) ATTENTIVE (Quieting or increased activity, Change in breathing rate, Onset or cessation of vocalizations, Onset or cessation of crying Eye widening, brow furrowing or expectant look, Smiling, Head turning – searching or localization)
45
When is Visual Reinforcement Audiometry used?
6 Months to 2 ½ years of age
46
What is Visual Reinforcement Audiometry?
Consists of stimulus/response conditioning A conditioned response is a new or modified response to a previous neutral stimulus
47
How accurate is Visual Reinforcement Audiometry?
High accuracy when conditioning achieved Minimal Response Levels obtained are within 10dB of true thresholds Speech Detection Thresholds (SDT or SAT) used as a cross-check to the audiometric thresholds obtained
48
What is happening in Auditory Development at 0-6 weeks?
Normal hearing children startle, eye ​ | blink or widen eyes to sounds at 40-80 dB HL
49
What is happening in Auditory Development at 4-7 Months?
Head turn laterally toward a sound, responds to speech at 20 dB HL tones at varying levels
50
What is happening in Auditory Development at 7-24 months?
Level of signals needed to elicit a head turn drops
51
What is happening in Auditory Development at 24+ months?
Conditioned play audiometry possible
52
When is Conditioned Play Audiometry used?
2 to 2 ½ and older
53
What is Conditioned Play Audiometry?
Child is trained to perform task in response to sound using a fun activity Motivates child to perform listening task Can pick a variety of games to keep child’s interest (e.g. block in bucket, peg board, puzzles, computer PowerPoint)
54
How is reliability in Conditioned Play Audiometry?
Good reliability when child is engaged in listening Speech Recognition Thresholds (SRT or SAT) used as a cross-check to the audiometric thresholds obtained

Determining the type and degree of hearing loss
