3. Joe goes to the audiologist complaining of a ‘stuffed-up’ feeling and trouble hearing in
his right ear. The audiologist finds the following: Type C tympanogram, absent
distortion-product otoacoustic emissions, and absent ipsilateral right ear acoustic
reflexes. What diagnosis will the audiologist probably make for Joe’s right ear?
a. Normal hearing
b. Conductive hearing loss
c. Mild sensorineural hearing loss due to a lesion in the cochlea
d. Severe sensorineural hearing loss due to a lesion in the cochlea
4. Jane’s right tympanic membrane is ruptured following a severe ear infection. Her right
sensorineural mechanism is normal. Which of the following statements is true?
a. Jane will have a B type tympanogram
b. Ipsilateral right ear acoustic reflexes will be absent
c. Distortion-product otoacoustic emissions will be absent.
d. All of the above
5. An audiologist is conducting the ABLB test on a patient. The following table shows the
growth of loudness in two ears. Assuming that the right ear is normal, which of the
following conditions in the left ear would produce these results?
a. Occlusion of the ear canal due to wax
b. A middle ear infection that has spread to the inner ear
c. A tumor of the auditory nerve
d. Damage to the cochlea because of noise

5. An audiologist is conducting the ABLB test on a patient. The following table shows the
growth of loudness in two ears. Assuming that the right ear is normal, which of the
following conditions in the left ear would produce these results?
a. Normal hearing (Not normal because higher SPLs are needed in the left ear
for equal loudness)
b. Occlusion of the ear canal due to wax (Equal loudness at equal sensation
levels)
c. A middle ear infection that has spread to the inner ear
d. Damage to the cochlea because of noise
