MIdterm Flashcards
Are Hearing and Understanding the same thing?
No
What tests hearing
puretone testing
what tests understanding
speech testing
What are the two ways for speech testing
CD and monitor live voicing (MLV)
What is speech detection
lowest level detecting a word. Not used all the time.
What is Speech recognition
lowest level you can hear and understand. try to do it
what finds speech recognition
houstin westlake
what is the houstin westlake
5+ 10-
What kind of words are used during a houstin westlake
spondees (hotdog)
how to find the puretone average
500 1K 2K divide by 3 be in range of 7 If it is more they are faking it
what is MCL
most comfortable loudness level
what is UCL
uncomfortable loudness level
What is dynamic range important for
hearing aids
what is the the difference between reliability and validity
validity measures what it says it will measure
reliability every time test is given test will reveal similar scores each time.
what are the three key factors for validity
test will measure what its supposed to
how well a test will compare to similar tests
how tests stands up to alterations of signal that are known to affect other speech test in specific ways
Is word recognition and SRT the same thing?
no
what is SRT
speech recognition threshold
what words do we use to test hearing and understand
monosyllabic
how many monosyllabic words are used when testing
50
When testing comfortable loudness level what do we turn it up to
40db
what are the two types of word lists
Phonetically balanced word lists(W22) and Consonant nucleus consonant word list(NU-6)
what are somethings about the Phonetically balanced word lists
phonetically balanced
not completely valid
took 200 words and made it into 4 lists
What are something about Consanant nucleus consonant word lists NU-6
CVC monosyllabic 4 list of 50 not phonetically balanced more valid reliable
can you mask for speech
yes
what is narrow band noise
noise for nontest ear for masking
when producing low pitches what do we add to accomidate to occlusion effect
15db
what is he scale we test for interpreting speech
90-100 excellent 80-89 good 70-79 fair 60-69 poor 59 and below very poor
what is the purpose for masking
prevent cross hearing
What is Interaural attenuation (IA)
same as cross hearing. Headphones on testing left leaks out and other ear better that can hear it. 40 db
What are Insert headphones db
70db
what method is used with the platoe
hoods
what are the symbols used for masking
mask air right Tringle
mask bone right [
Mask air left square
mask bone left ]
what is bone cnduction
platoe method
look at bone scores of non test ear
what is tympanometry
measure outter and inner ear pressure
too much fluid movement
can break ossicals
when fluid doesn’t move
cause blockage
what are the four components in the ear
ear canal volume
ear canal pressure
static compliance
width
what two muscles contract with acoustic reflex
stapedius and tensor tympani
what are the five results o fa tympanigram
Type A Type As(swallow) Type Ad(deep) Type B Type C look at pics on paper too
what level of sound do the mucles contract?
high sounds
What is Ippsiladeral
same
what is contralateral
opposite
what is OAE
otto acoustic omission
present or absent (screener)
what is ABR
auditory brain stem response
what does ABR do
measures brainstem
what wave is threshold
5th wave
when intensity goes down threshold does what
down
look at the drawing for bonus
the ear thing
