test 2 study 3

Question 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

Answer 1

otoacoustic emissions : inner ear

Question 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

Answer 2

otoacoustic emissions

Question 3

what are the two types of otoacoustic emissions

Answer 3

spontaneous (SOAEs)

Evoked (EOAEs)

Question 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

Answer 4

spontaneous otoacoustic emission

Question 5

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

Answer 5

25-30 dB

Question 6

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

Answer 6

Evoked OAEs

Question 7

two prominent EOAEs with prominent clinical applications are

Answer 7

distortion product otoacoustic emissions;

and transient-evoked otacoustic emissions

Question 8

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

Answer 8

FUNCTIONING

Question 9

probe has only one sound port for presenting stimulus

Answer 9

TEOAEs

Question 10

probe has 2 sound ports for the two distinct primary tones

Answer 10

DPOAEs

Question 11

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

Answer 11

30 dB

Question 12

what is the drawback of EOAE testing?

Answer 12

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

Question 13

what muscle is being contracted during acoustic reflex testing?

Answer 13

stapedius
