Test Interpretation Flashcards
progressive hearing loss
- deteriorate over time
- routine hearing exams following a hearing loss diagnosis
even though an infant passes a newborn hearing screening, doesn’t mean that…
they cannot acquire a loss later on
if a child is being seen by the SLP for the first time,…
you may need to rule out hearing loss as a contributing factor
speech audiometry: conductive HL
typically good speech understanding
speech audiometry: sensorineural
loss of speech discrimination ability
speech reception (recognition) threshold (SRT)
- validates pure tone results
- should be equal to (+/- 5 dB) PTA
- PTA and SRT are in agreement
what if the SRT and PTA are not in agreement?
- equipment malfunction
- misunderstanding of instructions by patient
- pseudohypacusis
pseudohypacusis
exaggerating a hearing loss
word discrimination testing
- scores reflect an appropriate level of the patient’s understanding of speech
- intensity is steady and loud enough for the person to comfortably hear the words
- 25-50 word list of monosyllabic words presented
- percent correct is determined
- no visual cues, only based on what they hear
other audiometric data
sound field unaided and aided
why test in the sound field?
- young children may not wear headphones
- cannot obtain separate ear information, better ear will respond
- testing hearing aids in vs. hearing aids out through the speakers
- verifying benefit of hearing aids
- testing cochlear implant thresholds through speakers
aided sound field testing symbols
- A = aided
- AR = aided right ear only
- AL = aided left ear only
- AU = aided bilaterally
- CI - cochlear implant threshold
otoacoustic emission (OAE) interpretation
test of cochlear functioning (outer hair cell function)
present OAE
- normal or near normal cochlear functioning
- assume normal hearing
absent OAE
- abnormal cochlear functioning, conductive HL or cochlear hearing loss greater than mild in severity
- refer for ABR testing
