Speech audiometry Flashcards
1
Q
What Tests are associated w/ speech audiometry
A
- SRT
- MCL
- WRS
2
Q
What does speech audiometry measure?
A
- Sensitivity
- Acuity
3
Q
Volume units meter
A
- to monitor the intensity of input source
- set up calibration so monitor peaks at 0 when you’re speaking
4
Q
Response types
A
- Oral (most common)
- Written
- Picture ID (for children, ELL, developmental, etc.)
5
Q
False positives
A
- possible when you don’t cover your mouth
- otherwise, not very common
6
Q
False negatives
A
- common
- may need to reinstruct
7
Q
Speech detection threshold (SDT)
A
- measure of sensitivity
- lowest level in dB that a subject can detect speech
- does NOT need to be understood
- not very useful, can get same info from pure tone test
8
Q
Speech recognition threshold (SRT)
A
- measure of sensitivity
- lowest level in dB that a subject can barely understand speech
- obtained with spondees
- good check for validity of pure tone thresholds
9
Q
Spondee
A
- two syllable word w/ equal emphasis on both syllables
10
Q
How to test SRT
A
- like pure tones
- 10 down, 5 up
- familiarize pt w/ words first
11
Q
Performance-intensity functions
A
- as you go up in intensity, you don’t have to go very high before people suddenly start getting 100%
- someone who plateaus (e.g. SNHL) won’t get 100%
- if they plateau then get worse, red flag for retrocochlear hearing loss
12
Q
Most Comfortable Listening level (MCL)
A
- use to find out what’s the most comfortable level for someone to listen to speech at
- use cold running speech
- measure of sensitivity
13
Q
Measures of acuity
A
- WRS
- use the level of MCL
- % correct rather than dB like in sensitivity
14
Q
Acuity
A
- to determine the person’s suprathreshold speech recognition abilities
- how well can a person distinguish the acoustic cues of speech above threshold?
15
Q
Word recognition scores (WRS)
A
- often called speech discrim but is NOT discrim task
- identify a word that was just spoken
- cannot be predicted from puretone audiogram
