Implantable Hearing Devices
The DEGREE of hearing loss that must be present in an INFANT (9-24 months) to receive a cochlear implant
Profound
____% of children with hearing loss are born to hearing parents
90%
According to the Joint Commission on Infant Hearing, a hearing screening should be completed by this age:
1 month
Which test uses electrodes?
True or False: You need to have a hearing loss to benefit from ALDs
False
This implantable device would be most appropriate if the patient had a damaged, abnormal, or missing auditory nerve
Auditory Brainstem Implant
This is the most important factor that impacts language development, according to Mary Pat Moeller (2000)
Family involvement
Newborn Hearing Screenings, universally implemented from JCIH, must be conducted using one of which two types of objective tests?
ABR or OAE
True or False: Both of these tests can be used in screenings and evaluations
True!
An ALD system that uses an FM receiver to send the signal to the student's ear but is NOT a hearing aid is called
Self-Contained FM System/ FM Amplifier
A BAHA can be anchored to the head using these THREE methods
Magnetic attachment, softband and an abutment
True or False: Signed Exact English and Cued Speech use their own syntax and grammar, separate from English
False
Before 3 months of age, an infant with a hearing loss should have what?
Diagnostic Evaluation
This is the most clinically important Wave in an ABR tracing
Wave V
This is the optimal SNR for children with normal hearing
+15dB
What type of BAHA uses osseointegration to ensure stability of the device?
Bilingual/Bicultural "bi-bi" learning approach is a significant aspect of which communication method?
American Sign Language (ASL)
And infant with hearing loss should be fit with hearing devices before what age?
6 months
This test is measuring an "echo" that is generated by the hair cells within the cochlea.
OAE
For every doubling of distance, sound level decreases by:
6 dB
A middle ear implant would be appropriate if a patient had a large, benign tumor removed from their middle ear space which resulted in damaged ossicles. What is this benign tumor in the middle ear called?
Cholesteatoma
Name the 5 communication approaches we discussed in class
Auditory/Oral, Signed Exact English, Cued Speech, ASL and Total Communication
Behind-the-ear (BTE)
These are disadvantages to which test?
-Sensitive to noise
-Only tests to the level of the hair cells (not higher)
OAEs
The 3 Factors that degrade SNR are noise, distance, and:
Reverberation
