Speech Audiometry Flashcards
What are the types of speech audiometry?
Speech Recognition
Speech Detection/Awareness
Word Recognition
Pattern Perception
What are the testing considerations for speech audiometry?
How do you calibrate the speech audiometer?
How do you calibrate the stimuli and transducer?
How do you decide your method of presentation?
SRT = 15 softer than best AC at 1000 Hz
What is redundancy and uncertainty?
Why do we test for speech?
What does speech audiometry do that puretone audiometry does not?
What are the limitations of speech audiometry?
What are the tests for hearing sensitivity?
SRT, SAT/SDT
What is the point of SRTs?
What are the different threshold levels?
MCL - most comfortable level
UCL - most uncomfortable level
LDL - loudness detection level
?? TD - threshold detection???
What is recognition in quiet?
What is recognition in noise?
What is phonemic regression?
Decrease in intelligibility of speech out of proportion to the pure tone hearing loss associated with aging
What is the PI-PB function?
Speech recognition performance depends on the intensity of the speech stimulus
Phonetically and Phonemically balanced words are used
What is the PB rollover?
Condition where WRS at a level above the PB-max is lower by 20%
Reduction of speech recognition scores that occur above PBmax
How many words should be included in the list - diagnostically?
At what intensity level(s) should you present word lists?
UCL-5
2OOO Hz rule
40 dB above SRT
What are the variables for word recognition testing?
How do you interpret WRS?
If patient’s MCL is 105 dB HL and the UCL is at 115 dB HL, you present the WRS stimuli in the right ear at the appropriate level, is masking necessary?
Yes
The lowest level at which a patient can hear speech
SAT/SDT
The lowest level at which a patient can correctly identify speech 50% of the time
SRT
Stimulus is any speech, including random running speech, strings of words, or singing
SAT/SDT
Stimulus is spondees
SRT
Stimulus is CVC or other monosyllabic words
WRS
Familiarization of word list is recommended
SRT
Corresponds to PTA
SRT
Corresponds to best threshold
SDT/SAT
Reported as percentage
WRS
Reported as dB HL
SDT/SAT/SRT
Suprathreshold measure
WRS
T/F: MLV testing yields a lower speech threshold compared to recorded testing
False
T/F: MLV testing is usually faster than recorded testing
True
T/F: Audiologist’s face needs to be covered or hidden when obtaining speech thresholds via MLV
True
What is the purpose of the VU meter?
Ensure MLV is neither too loud or too soft
“Say the word….” is an example of a ______________
carrier phrase
Example of WRS word lists
NU-6, PB-50, CID, W-22
Most WRS word lists are ___________ words in length
50
What is PBmax?
Maximum score on PI-PB function
Whenever possible, ___________ should be used to present WRS stimuli
recorded words
T/F: In general, with WRS testing, the presentation level is positively correlated with performance
True
T/F: In general, with WRS testing, presentation level has no significant impact on performance
False
What is PB-max?
Highest WRS a person can achieve across all possible presentation levels
Suppose Mr. A had a WRS of 80% in the RE and 60% in the LE. Based on Katz table, the difference is ____________
Significant only if the full 50 word list was presented
What presentation level are you are most likely to achieve PB-max in almost every patient without exceeding their UCL
5 dB below the patient’s UCL
