Flashcards in test 2 study 3 Deck (13):
1

low level sound emitted by the cochlea, either spontaneously or as an echo or other sound evoked by an auditory stimulus, related to the function of the outer hair cells of the cochlea

otoacoustic emissions : inner ear

2

______result from the activity of the outer hair cells in the cochlea; doesn't provide any info regarding the degree or nature of the possible hearing loss

otoacoustic emissions

3

what are the two types of otoacoustic emissions

spontaneous (SOAEs)
Evoked (EOAEs)

4

measurable low level sound that is emitted by the cochlea in the absence of stimulation; it is related to the function of the outer hair cells

spontaneous otoacoustic emission

5

spontaneous OAEs have not been recorded in the presence of HL greater than

25-30 dB

6

in contrast to the SOAE which is present without external auditory stimulation, EOAEs are measured during or immediately following acoustic stimulation

Evoked OAEs

7

two prominent EOAEs with prominent clinical applications are

distortion product otoacoustic emissions;
and transient-evoked otacoustic emissions

8

a TEOAE is NOT a test of hearing it is a test of outer hair cell cocker ________

FUNCTIONING

9

probe has only one sound port for presenting stimulus

TEOAEs

10

probe has 2 sound ports for the two distinct primary tones

DPOAEs

11

if EOAEs are absent, one can suspect cochlear hearing loss of greater than

30 dB

12

what is the drawback of EOAE testing?

many infants have fluid within the middle ear cavity so you can have a high false positive rate for permanent HL

13

what muscle is being contracted during acoustic reflex testing?

stapedius
