- Audiologist has the critical role because of brain access
- Everyone in a child's life needs to be involved in communication
- Hearing is access to auditory brain
- Sound must be clear
- Kids need more brain development with more repetition
- SNR is critical - FM is key
- Repetition in classrooms of what other kids say by teacher
- Any unoccupied class should be no more than 35dbs
- Need single events in classrooms for kids to hear
- What is the important sound going on in the classroom. Don't have two groups at the same time.
- Dominant tissue in brain is auditory designated tissue. Must be stimulated
- Earlier is better = brain had plasticity
- Earlier= more practice
- Brain is a probability organizer
- Typical babies are born with 20 weeks auditory development
- 20,000 hours of listening as a basis of reading
- Children with hearing loss need three times the exposure to learn new words and exposure
- Eyes open, technology on
- A child with four hours of aids will need six years to equal one year of an ordinary hearing
- Must have all three -Perfect technology, good program, and parents
- The real ear is the brain
- Must use a pediatric audiologists - All audiologists are not the same
- Children with profound loss at age 5 - 44% are progressive
- 40% of hearing aids were under fit (mp)
- Plan for a progressive loss
- Use FM at home
- Auditory access is not just at home
- Always suspect technology first if something is wrong
- Use Ling6 and 44 phonemes ****** (We heard test with phonemes multiple times)
- Noise noise noise - infants should have FMs
- Turn the music off unless it's adult directed
- Always walk out with a copy of the audiology report
- Behavior tests are more important than objective testing
- Do speech perception testing after mapping
- How does kid hear at 50db, 35db and noise at 5db - thresholds and discrimination each ear and binaural
- If you are not sure if your child is hearing they are not
- CIs should be mapped between 15 to 20 db
- Record specific phoneme errors
- Distance hearing
- Voice quality is an indicator
- Do lings naturally
- Speech perception qualifiers
Excellent 90-100
Good 80-89
Fair 70-79
Poor <70%
- Mild hearing loss places child at 10 times risk
