CH 7 - Speech Audiometry Flashcards
lowest level at which speech can be detected or recognized is called __ __
Speech threshold
lowest level where spondee words can be ID’d
Speech recognition threshold (SRT)
Theoretically, the SRT should be similar to the __
PTA
In a normal patient, how should speech recognition compare to what an audiogram would expect?
greater than or equal to
words with phonemes that occur within same frequency as conversational speech
phonetically balanced (PB) words
two-syllable words spoken with equal emphasis
spondaic
noun version of spondaic
spondees
it is easier for folks with hearing loss to hear ___ as opposed to single syllables because of the concept of __
sentences (or words), redundancy
these type of speech materials have a short list of possible correct answers
closed-set
these types of speech materials are fill-in-the-blank, answer-wise
open-set
what is the difference between SDT and SRT?
DT = aware of the presence of speech
RT = can identify words
another word for SDT
speech awareness threshold (SAT)
How similar should SRT and PTA be to each other?
5-10 dB
in word recognition testing, the tester uses __ words at a __ intensity level above the threshold
monosyllabic; fixed
what dB level do you use for WRT?
Air conduction threshold at 2K Hz + 20 dB
WRT testing uses ____ words, and SRT testing uses ____ words
monosyllabic; spondees
in WRT testing, the intensity levels ___
in SRT testing, the intensity levels __
stay the same; change
why is speech audiometry useful for hearing aids?
tells us if amplifying sound will actually help - if it’s a processing thing, it may not
two types of redundancy
intrinsic and extrinsic
intrinsic redundancy in contained here:
central auditory nervous system
extrinsic redundancy contained here:
speech signals
what is the challenge with redundancy in testing?
Middle ground in testing: accessible, but actually testing hearing and not our ability to figure it out
what are the four categories speech audiometry can fall into?
1) SDT
2) SRT
3) WRS
4) Sensitized speech measures
Most common way we describe suprathreshold hearing ability
WRS
intensity level of sound in decibels above a person’s threshold
sensation level (SL)
SRT uses ____ samples and WRS uses ___ samples
spondee; monosyllabic
What is the goal of a word recognition test?
assess patient’s ability to ID and repeat monosyllabic words at suprathreshold levels
intensity level of sound in decibels above a person’s threshold
Sensation level (SL)
decrease in speech recognition ability with increasing intensity level is called
rollover
what is this?
rollover
what are the six descriptors use for WRS?
excellent
very good
good
fair
poor
very poor
proportion of speech signal that is audible to patient
Audibility index (AI)
counting the dots is related to what?
audibility index
