BAI – Sound processor attachment has TWO methods of attaching a processor. What are they?
*Extra point* Describe them!!
Percutaneous : an abutment is attached to implant and comes through the skin (Direct Drive)
◦ Provides best sound quality
◦ More prone to infection
Transcutaneous: a magnet is attached to the implant and is completely under the skin (Skin Drive)
◦ Poorer sound quality (less access to high pitches)
◦ Less likely for infection
◦ Prone to fall/be knocked off of the head
When does the best admittance occur?
When the pressure in front of
the eardrum MATCHES the
pressure behind the eardrum

Dichotic Listening (Speech Tests) – Different words or sentences presented to each ear, but patient listens only in one ear
Monaural Low-Redundancy – Filtered speech, compressed speech
Lateralization, localization, or binaural functions
Auditory Discrimination Tests – Frequency, intensity, and duration of speech stimuli
Name syndrome that is the most common Autosomal Recessive and can be noticed by a THYROID dysfunction

CAPD Treatment
Describe the difference between bottom-up and top-down.
Bottom-Up (stimulus driven):
-Auditory training
-Skills remediation
-Environmental modifications including assistive technologies
Top-Down (strategy driven):
-Language, cognitive, metacognitive strategies
-Educational interventions
-Workplace, recreational, and home accommodations
