that is battery powered which broadcasts directly to students FM amplifier units. The receiver unit may be powered by a rechargeable battery. This unit can serve as an individual hearing aid to pick up environment sounds only, FM sounds only, or a combo of the two.
- Infrared system: not used in a classroom, but usually auditoriums. Used infrared light, which is not visible to the naked eye. They pick up signals from the microphone. (look at handout)
New Developments in Aural Rehabilitation
· Used in patients with ear pathology refractory to medical or surgical intervention
Receiver/transducer implanted in temporal bone
· Middle ear implants (MEI)- output transducer implanted in middle ear
· Improve acoustics: amplify speech and limit background noise
· Hearing aid uses couple ALD via Telecoils
-internet part is under the scalp connected to an array of electrodes. Once in the cochlea it goes into the 8th nerve.
-external part has an outer unit (transmitter with a magnet that connects to the scalp) (p. 259)
candidacy for cochlear implants (p.262)
- prepare child/family for surgery and follow up
- initiate contact with educational services
-children's implant profile (ChIP)
parental support/level of expectation
educational environment/support services
- communicate pre-implant speech/language abilities
- acts as liaison with the cochlear implant center
- placement of internal receiver and electrode array (facial nerve??)
- air travel (varies with surgeons)
- 3-4 weeks after surgery switch on is completed
- device dispensed and set via computer software unique to the particular implant device – these setting known as the MAP
- counseling family and professionals about wear and tear of implant
- child connected to computer through speech processor via connecting hardware
- no two children will have the same map
- maps must be readjusted periodically
