Quiz 2: Electrophysiologic Measures and Otoacoustic Emissions

electroencephalogram (EEG)

through sophisticated computational techniques, auditory evoked potentials are extracted from

cranial nerve 8 via lateral lemniscus / inferior colliculus

the auditory brainstem response reflects neural activity from what structures in the auditory pathway?

Auditory threshold prediction in infants and children

Neonatal hearing screening

Differentiating between cochlear and retrocochlear disorders

Intraoperative monitoring

list 4 clinical applications of auditory brainstem response (ABR)

broadband clicks, tone bursts

list 2 stimuli ABR is elicited by

V

ABR threshold corresponds to the softest intensity level at which wave ___ can be still observed

false

true or false: the ABR is adversely affected by patient state (sleeping vs awake)

false

true or false: on average, the ABR waveform for newborns is almost identical to that observed for adults

true

true or false: the ABR can be obtained via both air- and bone-conduction

true

true or false: the frequency specificity of the ABR can be improved by the use of tone burst vs click stimuli

auditory neuropahty spectrum disorder

despite their lack of frequency specificity, click-evoked ABRs serve an important role in diagnosing which conduction?

low intensity sounds emitted by the cochlea

what are otoacoustic emissions?

Infant hearing screening

Pediatric audiological assessment

Monitoring cochlear function

Differentiating cochlear vs retrocochlear function

list 4 clinical applications of auditory otoacoustic emissions

broadband clicks

transient-evoked otoacoustic emissions (TEOAEs) are elicited using what type of stimuli

tonal pairs (f1 and f2)

distortion-product otoacoustic emissions (DPOAES) are elicited using what type of stimuli?

true

true or false: transient-evoked otoacoustic emissions (TEOAEs) are generally absent when cochlear hearing loss >/= 30 dB HL

true

true or false: distortion product otoacoustic emissions (DPOAEs) are generally absent when cochlear hearing loss >/= 50 dB HL

false

true or false: otoacoustic emissions can be measured in the presence of middle ear disorder

false

true or false: OAEs are adversely affected by patient state (sleeping vs awake)
