Speech Audiometry Flashcards
What is the purpose of Speech Audiometry?
It determines the degree of disability in speech communication caused by hearing loss
For speech audiometry, what test equipment is used?
- Audiometer
- 125-12000 Hz
- -10- 120 db HL - Transducers (mostly air conduction equip)
- Speakers
- Earphones
- Bone oscillator
Which equipment is not typically used for Speech Audiometry?
Bone oscillator
Why is a bone oscillator not used for Speech Audiometry?
- It’s not typically calibrated for speech
- Is unreliable for assessment purposes
- It’s not comfortable since a patient can get a vibrotactile response
What background information regarding Speech Audiometry is like Pure Tone?
- Testing environment
- Testing Chambers
- Criterions to keep in mind for patients
- Positioning
- Response (first 6)
For Speech Audiometry, regarding the patient’s speech-language, what should an Audiologist know?
- The patient’s speech-language difficulties
- Patient’s receptibility to understand
- Tester’s ability to understand response for scoring purposes
Between Speech Testing and Pure-tone Testing which one is a bigger problem for the patient?
Speech testing
For Speech Audiometry, what are the types of responses?
It depends on the test
1. Hand raising
2. Finger raising
3. Signal button
4. Vocal response
5. Conditional Play Audiometry
6. Visual Reinforcement Audiometry
7. Pointing to pictures
8. Writing
For Speech Audiometry, can false response occur?
Yes
How can a false positive response occur for Speech Audiometry?
- For awareness task - it can happen if they happen to press the button at the right time
- Word identification - if pictures are used, pt can potentially guess the right answer?
What does monaural mean?
An audiologist testing each ear individually
What does binaural?
An audiologist testing both ears simultaneously
What are the benefits of using binaural testing?
- Two ears are better than one demonstrates binaural benefit
- Important for hearing aid candidates
For binaural, why is 2 ears better than one?
There’s a boost when they’re both working together vs working in isolation
With binaural testing, why is this test done for hearing aid candidates?
- To convince people to get 2 hearing aids when they have a HL in both ears
- Occasionally, the test can prove that the pt does not need 2 hearing aids
From a binaural test, why might a hearing aid candidate be turned away from receiving 2 hearing aids?
The poorer ear may bring the better ear down. The poorer ear hears noise and junk, and this will affect the better ear from processing sound
What are the 2 options of how a pt can hear the speech sounds?
- Monitored Live Voice
- Recorded Speech
What is Monitored Live Voice (MLV)?
An actual tester’s voice that uses a microphone and monitoring system through audiometer
What is Recorded Speech?
Is a CD or tape recording of voice and a calibration tone on recording to monitor
What are the two Speech Threshold Testing?
- Speech Detection/Awareness Threshold (SDT/SAT)
- Speech Recognition Threshold (SRT)
What is SDT/SAT?
It’s the lowest level at which one can barely detect the presence of speech and identify it as speech
For SDT/SAT what are the patient’s thoughts?
” I am aware that there is speech but can’t recognize the words”
For SDT/SAT testing, what are the stimulus?
- Words
- Cold Running Speech
For SDT/SAT testing, while giving the stimulus, what are we still doing?
- 2/3 - words recognized
- Down 10 up 5
For SDT/SAT, what are the type of responses?
Hand raise, finger raise, push button etc
What is SRT?
The lowest level at which 50% of speech is correctly understood
For SRT what are the patient’s thoughts?
” I can hear the speech but i’m still not sure what’s being said but once you increase the volume, I can hear it now”
What are the stimuli for SRT?
- Spondees
- Carrier Phrase
What are spondees?
Is a two-syllable word with each syllable being produced with equal stress and effort (airplane)
What is a carrier phrase?
A phrase you hear before the spondee is given to the pt for them to respond to
For SRT, what is the threshold search?
It’s the same procedure as for pure tones (down 10, up 5)
For SRT, what are the responses?
Oral, pointing, and writing
For Speech Threshold Testing, what are the other types of responses?
- Closed
- Open
For Speech Threshold Testing, what is an open response?
Where pt must produce the answer an infinite # of responses without receiving a response
