Auditory Rehabilitation Flashcards
decisions regarding the best approach are guided by factors such as ? with the ultimate goal of ?
age of the person and type of hearing problem
improving indiv. quality of life
aural rehabilitation : techniques used with people who are ? these individuals once?
aural habilitation:
hearing impaired to improve their ability to communicate
- demonstrated normal hearing
- techniques used with people who are hearing impaired at birth
only 1/5 people who could benefit from a hearing aid ?
actually wear one
what is a hearing aid? a hearing aid is an ? sound hits ? --> ...--->transmitted to a ----> delivered to some hearing aids use a ? some are ? may be used in ?
electronic device that amplifies sound
microphone , amplification, mini loudspeaker (speaker/receiver), patient’s ear
-bone conduction vibrator
-partially or fully implanted
-conductive, sensorineural, or mixed losses
hearing aids:
3 basic parts
microphone
amplifier
speaker
treatment of hearing loss hearing aids don't just? amplify ? and compress? amplify sounds only for ? -... or.. chunks depending on ? amplify? diminish?
amplify sound signal/ intensity differences frequencies most impaired smaller or larger/sophistication of hearing aid speech/noise
common myths they will ? they get rid of ? my mama hated her hearing aids so ? they will be as easy to adjust as
restore hearing to normal
background noise
i will too
eyeglasses
benefits of binaural amplification
better?
better?
other thoughts…
auditory ? if left unaided
small percentage of patients have ?
clarity in background noise
localization
deprivation if left unaided
decreased performance when aiding the poorer ear
types of hearing aids - - - - older types - -
behind the ear BTE
in the ear ITE
in the canal ITC
completely in the canal CIC
body type aid
eyeglasses
open fit hearing aids type of ? over ? of hearing aid market smaller than traditional ? better ? what design ? often incorporating ? -no/less
BTE 40% of hearing aid market BTEs with thin tube / cosmetics open design ear tip receiver -occlusion
RIC receiver in the canal
many open fit hearing aids incorporate ?
advantages:
receiver into the ear bud that sits in the canal
-reduces feedback, extends fitting range
Bone conduction hearing aids patients with ? patients who cannot use air conduction hearing aids for other? patients with ? the transducer is a? placed on the? vibration of the ? stimulates both ? from a single ?
conductive loss otologic reasons (persistent or recurrent ear drainage, canal abnormalities) single sided deafness (SSD) vibrating receiver/mastoid process skull cochleas BC instrument
Bone anchored hearing aid (BAHA)
works by taking the sound from
outside and transmitting it to inner ear through the bone
Implantable bone conduction devices (BAHA)
surgical placement of a bone conduction aid
Cochlear implants
a surgically implanted ?
cochlear prostheses that bypasses the damaged peripheral auditory system to directly stimulate the VIII nerve for hearing
cochlear implants
works by transmitting signals sent through the skull to an
array of electrodes situated along different regions of the cochlea
cochlear implants auditory nerve must? tiny ? threaded through ? connected to radio receiver under ? signals transmitted from ? signals stimulate ? doesnt sound ?
be intact flexible coil (24 microelectrodes) round window and into cochlea scalp/microphone behind ear AN fibers normal
Treatment approaches: SLP rehabilitation
concerns treatment of the speech and language abnormalities that may ?
these may include
accompany hearing impairment
- language
- articulation
- voice
- prosody
Rehabilitation approaches
speech reading cued speech oral/aural approach SimCom manual approach
Cued speech uses ? talker speaks while ? individually, the hand signals are ? they are used to ? has been adapted to more than ?
phonemically-based hand gestures to supplement speechreading
- cueing message
- uninterpretable/distinguish viseme members
- 60 languages
Aural/oral language
same language used by those with ?
child will speak messages and use ?
children using a multisensory approach use both ?
in small pocket, a unisensory approach is advocated where reliance on ?
normal hearing
speechreading to receive messages
-vision and hearing to recognize speech
-visual speech signal is not encouraged
The tech
current tech allows a child
-to have access to
-to learn to talk through
-to have listening as a major force in their?
the development of spoken language depends upon the individual student’s access to a ?
- spoken language
- listening
- personal, social, and academic development
a maximized and consistent auditory signal
SimCom
comprised of ? corresponding to the words of ?
person speak simultaneously while
called ? the child uses every available means to ?
can ?
manual signs / english sharing syntactic structures
signing
total communication/receive message, including sign, residual hearing, and lipreading
fingerspell those words that do not have a sign
sign language manual system of ? - - - - other countries have
comm. expressed by hands through
-configuration
-orientation
-location in space
-movement
comparable systems
