Flashcards in praxis audiology Deck (31):
1

acoustic neuroma

tumor on acoustic nerve:
normal ability to detect pure tones,
normal speech recognition in a quiet room,
unilateral facial tingling
& ringing,
slight dizziness,
mild balance problems

2

carharts notch

reflects specific loss at 2000 Hz
as indicated by bone-conduction testing,
often reflected in otosclerosis audiogram

3

conductive hearing loss

outer or middle ear malfunctions

4

CN VIII

vestibular & auditory-acoustic branches,
carries electrical sound impulses from the cochlea to the brain

5

presbycusis

hearing impairment in older people,
resulting in a sloping, high-frequency loss

6

menieres

causes sensorineural hearing loss,
accompanied by vertigo & tinnitus

7

signal to noise ratio

separating
signal of interest (speech)
from background noise

8

homophenous pairs

visible labials that look the same & may be confusing
"man-ban"

9

tensor palatini

exerts the pull that allows the eustachian tube to open
during yawning & swallowing

10

cleft palate hearing problems

frequently eustachian tube dysfunction
bc of oral-facial anomalies

11

SRTs

(speech reception thresholds)
lowest level of hearing
at which a person can understand
50% of words presented

12

aural/oral method emphasizes

making use of residual hearing through amplification,
& helping learn to communicate to be comfortable in mainstream settings with hearing people

13

deaf speech characteristics

omission of /s/ in all word positions,
cons cluster reduction,
occasional irrelevance of speech
including non sequiturs,
improper stress patterns
including excessive pitch inflections

14

outer ear

auricle/pinna
& external auditory canal

15

middle ear

air-filled cavity,
separated from outer ear by tympanic membrane,
contains ossicular chain,
eustachian tube connects to nasopharynx

16

hearing loss

normal: 15
mild: 16-40
mod: 41-55
mod-severe: 56-70
severe: 71-90
profound: 90+

17

communication training
approach emphasis

verbal (total communication & aural/oral approach)
or nonverbal (sign language)

18

communication training

auditory training,
speech reading,
cued speech,
training in subsystems

19

reflexive response techniques

used to assess infants & children with hearing loss

20

aural rehab

implemented by team
to help people with HL achieve their full potential

21

HL severity

depends on age of onset,
& degree of the loss,
communication disorders may manifest in 1+ subsystems

22

retrocochlear damage

employs electrophysiological audiometry & medical imaging,
damage usually caused by tumors
which can grow slowly
& make diagnosis challenging

23

acoustic immitance testing

involving tympanometry or acoustic reflex testing,
used to assess middle ear function

24

hearing impairment assessment procedures

depends on nature of the problem,
pure-tone & speech audiometry
carried out through air- or bone-conduction testing

25

auditory nervous system impairments

manifested by central auditory & retrocochlear disorders,
challenging to assess

26

oral training

language stimulation programs teaching successful expression,
functional words, structures & concepts, pragmatic skills,
important to use visual cues

27

auditory training

teach person to listen to amplified sounds,
recognize their meanings,
& discriminate sounds from each other

28

hearing aid types

eyeglass variety,
body aids,
BTE,
in the canal,
completely in the canal,
in the ear,
disposable

29

severe hearing loss

difficulty understanding even loud & amplified speech,
significant difficulty in learning & producing intelligible oral language

30

sensorineural hearing loss

inner ear malfunction,
damage to hair cells of the cochlea
or acoustic nerve

31

inner ear

most complex,
oval window in temporal bone,
vestibular system contains semicircular canals,
cochlea filled with endolymph,
basilar membrane floor contains organ of corti
