Speech audiometry (final exam) Flashcards
Where is testing for speech audiometry done?
In a sound treated room
What type of audiometer is used for speech audiometry?
Diagnostic audiometer
What is the stimuli for speech audiometry?
Speech
How can the stimuli for speech audiometry be presented?
Live voice or recorded
Which stimuli presentation is more standardized and more easily compared?
Recorded
Which stimuli presentation allows for more flexibility?
live voice
How is live voice stimuli presented?
The audiologist wears headphones and presents the words through a microphone
In what scenario is recorded stimuli not the best option?
Geriatrics or kids. You do not have flexibility with time so anyone with a processing delay will struggle.
Describe giving the patient instructions before testing.
Be specific as to what you want the patient to do
Can be verbal or written instructions
use hearing aids when you are giving instructions and remove for testing
Gestures can be used during instructions
What are 3 ways a patient can respond during testing?
Verbal, written, or gesture/point to a picture
What is an advantage and dis advantage of verbal responses?
Advantage- quick
Disadvantage- variations/accents
What is a disadvantage to written responses?
prolongs the test
What is an advantage and disadvantage of gesture/point responses?
Advantage- good for people who are non-verbal
Disadvantage - prolongs the test
What does SRT stand for and what is it?
Speech recognition threshold
lowest intensity where spondaic words can be understood 50% of the time they are presented
What is a carrier phrase?
Let’s the client know to focus/ that the word is coming
“Say the word…”
“Can you say…”
“You will say…”
When doing SRT testing, what should you do if the client can see you? Why?
Cover your mouth
Someone with HL can probably read lips well
They may be looking for cues to see if they are right or wrong
What is the recommended SRT procedure?
Start at 30dbHL, present a spondaic word with the carrier phrase, if the person repeats correctly you will decrease by 10dbHL, present another spondaic word with carrier phrase, if they get it correct decrease by 10, if they get it wrong, increase by 5dbHL, you want 2 correct responses at a certain dbHL level
How can you check for intertest reliability?
If SRT and PTA are within 10dbHL then there is intertest reliability.
What does SDT stand for? What is it?
Speech detection threshold
The lowest intensity level where speech is barely detected as speech; patient recognizes the stimulus as speech
Done in discourse rather than single words
Which is lower in intensity? SDT or SRT? why?
SDT because the person just has to recognize that it is speech, they don’t have to repeat back a word
Why is bone conduction SRT beneficial?
A child will not participate in pure tone testing
Verify or rule out middle ear involvement
With bone conduction, the better ear is responding
What does MCL stand for? What is it used for?
Most comfortable loudness
It is used to fit hearing aids
What does UCL stand for? How is it presented?
Uncomfortable loudness level
Running discourse is used “Hows my voice sound here?” fine.. increase by 5dbHL. Continue until they say stop
How do you find range of comfortable loudness?
SRT + MCL + UCL
What test looks at a patients ability to understand monosyllabic words at MCL?
Word/speech Recognition Test
What are the 4 speech audiometry tests?
Speech recognition threshold testing
Most comfortable loudness
Uncomfortable loudness level
Word/speech recognition test
Describe word recognition testing. What type of words are used? Size of lists? How do you keep track?
Monosyllabic words
50 word lists, phonetically balanced
Half lists—25 words to each ear
Presented at MCL
Check off incorrect or unheard words
What are 5 different types of word lists?
PBK lists (phonetically balanced for children)
Spanish lists
Nonsense lists
High frequency lists
Short isophonemic lists
Can you repeat a word you said during testing?
Yes but only if they do not respond or say “i didn’t get that” and you can only repeat once.
How do you score word recognition?
Each word is worth 2 points or 4 point for a half list. Subtract incorrect responses from 100. That percent is your score
Break down the test result scores for word recognition testing and what they mean
90-100% - excellent 80-89% - good 70-79% - fair 50-69% - poor below 50% - very poor
What kind of hearing loss will there still be a good/excellent word recognition score?
conductive HL and normal hearing
Type of hearing loss where the greater the thresholds the worse the WR score (be very specific)
Sensory/neural with cochlear damage
Type of hearing loss where there will be a lower WR score that expected as per the thresholds on the audiogram
Sensory/ neural with neural damage
What is PB - Max
Highest word recognition score obtained with phonetically balanced word lists on a performance intensity function
Predicts the amount of audible speech information for a given audiogram
Audibility index
How do you find audibility index?
Count dots above thresholds. Subtract that number from 100.
Tests that you may give to someone who is not verbal or not verbally cooperating
Closed set tests
Name 3 closed set tests
WIPI (word intelligibility by picture id test)
PIT (Picture identification task)
CCT (California Consonant test)
How does WIPI work?
Given certain choices and the answer is among those choices given
Carrier phrase is given. 6 pictures in front of them and they must point to the card that he/she may have heard
How does PIT work?
Pictures of rhyming words arranged in sets of 4
Patient Points to correct picture of what they heard
How does CCT work?
100 monosyllabic words on 2 lists
Given answer sheet. Patient is given 4 possible choices, marks choice on answer sheet
What is the QuickSin test?
Quick speech in noise test
Estimates the patient’s difficulty hearing with background babble present
Six sentences with people talking in the background, five key words per sentence, no context to words
Is masking necessary for speech tests?
yes
