Immittance and Middle Ear Assessment
Immittance is
Assessment of middle ear function
Anotia is
True or False:
CAPD is a nervous system auditory deficit that interferes with auditory information processing that is NOT a result of other high-order cognitive, language disorders
True
Hearing loss accompanied by additional clinical features is
Syndromic hearing loss
What bypasses the natural hearing system
Cochlear implants
True or False
Tympanometry is the measurement of impedence as a fucntion of pressure changes in the ear canal
False, it's a measurement of admittance
Surfer's ear is called
Exostosis
The three major profiles of CAPD are
Decoding deficits, Integration deficits, and Prosodic deficits
What is the most common syndromic hearing loss?
Usher Syndrome
What is the BEST way to measure hearing
aid output?
Real-Ear verification
Admittance is
measure of how much energy passes through a system
What is Presbycusis and what frequency does it start at?
Age-related hearing loss
Starrs at high-frequency SNHL, then moves to other frequencies
CAPD Treatment for Bottom-Up (stimulus driven) could include:
- Auditory training
- Skills remediation
- Environmental modifications including assistive technologies
Describe Usher Syndrome 3
Most rare
Hearing: Late onset, progressive HL until profound (3rd decade of life), vestibular problems vary
Vision: Variable progression of RP
List the hearing aid fitting workflow
Assessment, treatment planning, selection, development, verification, orientation, validation
What is the correct probe tone fo adults?
226 Hz
What is an Acoustic Neuroma and what could this result in?
Benign, slow growing tumor at the 8th Cranial Nerve
Could result in a unilateral high-frequency SNHL with Tinnitus and poor word recognition
Name 3 activities people with CAPD might have trouble with
Hearing on the phone, ability to localize sounds, following directions
What month is distinguished as having the first auditory experience?
July or 7th month
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
What are we measuring during a tympanometry?
1. Pressure
2. Admittance/Compliance (peak pressure) or YTM
3. Ear canal volume (ECV)
What are the 6 (OME) or Otitis Media with effusion?
Effusion, serous, acute, chronic, mucoid, glue ear.
Describe 1 CAPD Testing Measures:
-Temporal Processes – Pattern perception, gap detection
-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
Describe Teacher Collins Syndrome
INHERITANCE = Autosomal Dominant
Affects development of the bones and tissues of the face and often affects jaw
Roughly 1/2 have hearing loss
-Generally conductive hearing loss
Name 3 Digital Hearing Aid Features
Multiple channels/programs, compression, directional microphones, feedback reduction, linked hearing aids, data logging
