Q

Sensorineural Hearing Loss (SNHL)

A

Hearing loss resulting from inner ear or auditory nerve damage (cochlea, hair cells, or auditory nerve)
difficulty in sound perception and clarity, especially in noisy environments
May experience tinnitus and/or dizziness
Possible causes: NIHL, presbycusis, ototoxicity, acoustic neuroma, meniere’s disease, etc.
Treatment: hearing aids, cochlear implants
AC and BC abnormal, with NO ABG
Impacts HIGH frequencies most

Q

Cookie Bite Audiogram

A

A characteristic dip in the mid-frequency range (1000-3000 Hz), often associated with SNHL
Symptoms:
Difficulty understanding speech in noisy environments
Muffled or distorted sound quality in the mid-frequency range
Intact high frequency hearing (birds singing or children’s voices) and low frequency (thunder)

Q

Cochlear Implant Candidacy

A

Age: 9–12 months old, with earlier implantation (before 3 y/o) showing better outcomes for speech and language
Degree of Hearing Loss: Severe-to-profound bilateral sensorineural hearing loss (>70–90 dB HL) with limited benefit from hearing aids after a 3–6 month trial.
Medical Factors: Adequate cochlear and auditory nerve anatomy confirmed via imaging, with no contraindications for surgery.
Speech and Language: Delayed development despite appropriate amplification and intervention.
Family Commitment: Active involvement in therapy, realistic expectations, and willingness to manage the device long-term.

Dynamic Assessment

A

model of assessment that evaluates a child’s ability to learn and generalize after being taught.
Test: Initial evaluation of skills.
Teach: Targeted teaching.
Retest: Re-evaluation to measure progress.

Q

AAC Participation Model

A

Everyone can communicate!
External factors considered as potential barriers to be addressed, not restrictions
Assessment is ongoing
intervention facilitates meaningful communication and participation, identifies actual and opportunity barriers
Technology does not make a competent communicator

Q

AAC strategies

A

most efficient and effective ways to convey symbols

17
Q

AAC techniques

A

how messages are physically transmitted (e.g. scanning)

18
Q

AAC direct selection

A

touch, point or use eye gaze to pick options - do it with your own body
Fast, can use key guards to help with precision
For users with good motor control

19
Q

AAC indirect selection

A

The patient relies on a secondary method to make a selection.
Visual/Auditory Scanning, Partner-Assisted Scanning

20
Q

core vocabulary

A

common words to age matched peers; used across all communication environments

21
Q

fringe vocabulary

A

specific and unique vocab based on the AAC user; allow expression of ideas, mostly nouns

22
Q

AAC static display

A

“fixed” symbols in location, typical low tech

23
Q

AAC Dynamic display

A

electronic visual symbols, computer screen display

24
Q

AAC visual scene

A

picture/photo that represents a situation/experience within a scene
