VERIFIED ANSWERS
ELF - Answer-Early Listening Function is used to learn a child's listening bubble (close,
medium and far away) for different levels of sounds. Observations are made by a parent
and kept track of on a form.
COSI - Answer-Client Oriented Scale of Improvement is a subjective hearing aid
outcome measure via patent reports of where they would like to hear better and rates of
change in hearing from the situations they identified previously
Typical Hearing Aid lifespan - Answer-6-8 years
(assuming $6000 a pair --> approx $2.50/day for 7 years)
a cochlear implant improves _________ frequencies, improving ___________ -
Answer--high and speech understanding
hearing aids improve __________ frequencies, improving _____________ - Answer--
low and quality of sound
How do cochlear implants work? - Answer--electrodes are inserted into the cochlea to
electrically stimulate auditory nerve fibers
-microphone picks up sound and converts it to electrical energy
-processor codes electrical signal
-transmitter transforms signal to radio wave
- magnet, antenna, Receiver (under skin) picks up radio signal and changes it back to
electrical
- (16 to 22) electrodes deliver electrical impulses to areas of auditory nerve
Adult requirements in order to receive cochlear implant: - Answer--moderate to profound
SNHL in both ears
children (2-7 years old) requirements for cochlear implant vs children ( 12-24 months): -
Answer--(2-7) severe to profound SNHL in both ears
-(12-24 months) profound SNHL in both ears
MAPPing - Answer-Making a Program for Patient
-translate sounds into electrical pulses that stimulate the electrodes, audiologist uses a
computer to adjust each electrode to levels that allow the patient to best hear
FM system - Answer--Has a microphone/transmitter and a receiver that allows the
listener to use a headset, earphone, or hearing aid which pick up the sound directly
from the transmitter.
- 1 to Many
