Audiology, Elizabeth Feldman, 8/26/12.

Front 1

What are common symptoms of Meniere's disease?

Back 1

Hearing loss, dizziness, tinnitus, and fullness in the ear. Can have unilateral, fluctuating and progressive symptoms.

Hint 1

Disease of the cochlea.
Excessive endolymph.

Front 2

What is a Spondee threshold test?

Back 2

When two-syllable words with Equal stress on each syllable are used as stimuli during threshold testing to obtain the Speech Reception Threshold (SRT).

Front 3

What is the normal Ear Canal Volume for an adult?

Back 3

.3-1.6cc depending on the age and size of the patient.

Front 4

What does an ECV of .33cc indicate on a tympanogram?

Back 4

When there is a small ECV on a type B tympanogram, there is an abnormally small canal volume. This indicates that there is an obstruction in the outer ear canal which could be from cerumen (ear wax) impaction (blockage).

Front 5

What are behavioral issue characteristics of a child with an auditory processing disorder in a school setting, but has been tested to have normal hearing and vision?

Back 5

The child will demonstrate behaviors such as difficulty following classroom directions, transitioning, and understanding speech in background noise.

Front 6

What is used to cross check for pure tone thresholds?

Back 6

SRT, because it can estimate an individuals hearing sensitivity in the frequency region where speech falls on the audiogram.

Front 7

Why would masking be performed during bone conduction testing?

Back 7

Masking is performed on the non-test ear. Noise is presented to the non-test ear to keep it occupied while finding results for the test ear.

Front 8

What is a Type A audiogram?

Back 8

Normal function of the middle ear.

Front 9

What is a Type B audiogram?

Back 9

Fluid in the middle ear.

Hint 9

Tympanogram is flat or slightly rounded.

Front 10

What is a Type C audiogram?

Back 10

Negative pressure in the middle ear.

Hint 10

Peak of tympanogram in the negative pressure region.

Front 11

What is the difference between the SAT and the SRT?

Back 11

The SAT (Speech Detection Threshold) is the threshold for detection of speech and the SRT (Speech Recognition Threshold) is the threshold for recognition of speech.

Front 12

Describe the characteristics of otosclerosis.

Back 12

Otosclerosis is described as the increase in the stiffness of the middle ear. It is an abnormal growth of bone around the footplate of the stapes, which fixes it in place within the oval window. Due to the bone growth, the transmission of sound is affected through the ossicular chain to the inner ear.

Front 13

Elevated thresholds on a tympanogram are helpful in assessing what issues?

Back 13

middle ear function, an estimation of cochlear hearing loss, and the difference between 8th nerve and brain stem disorders.

Front 14

Retrocochlear losses result from what possible pathologies?

Back 14

Changes to the VIIIth nerve or to the auditory brainstem. Causes can include tumors (e.g., cochleovestibular schwannoma). An ABR test is a good assessment tool for the functioning of the VIII nerve and brainstem.

Front 15

What are symptoms of Retrocochlear hearing loss?

Back 15

Assymetric hearing loss, tinnitus (ringing in the ears), poor speech discrimination, and dizziness.

Front 16

Which screening tool is used for testing newborns?

Back 16

Otoacoustic Emissions (OAEs). OAEs can be obtained quickly and without cooperation of the baby (baby can be sleeping).

Front 17

The stapedious is innervated by which cranial nerve?

Back 17

VII Facial

Front 18

Describe a conductive hearing loss on an audiogram.

Back 18

gap between air and bone conduction with normal bone and air conduction more depressed (air-bone gap)

Front 19

What are characteristics of a conductive hearing loss?

Back 19

Caused from impacted cerumen (ear wax), perforated tympanic membrane, fluid in the middle ear, and otosclerosis. Conductive hearing loss can be medically treated and corrected. With a conductive hearing loss there is a change in the outer or middle ear which affects the conduction of sound to the cochlea.

Front 20

What are characteristics of a sensorineural hearing loss?

Back 20

Caused from excessive noise, ototoxic drugs, and viral illnesses; resulting in damage to the cochlea. Sensorineural hearing loss cannot be medically treatable and is not reversible.

Front 21

Describe sensorineural hearing loss on an audiogram.

Back 21

bone conduction and air conduction thresholds will be equal and elevated.

Front 22

Describe a mixed hearing loss on an audiogram.

Back 22

There will be an air-bone gap, with thresholds elevated for bone conduction and air conduction.

Front 23

Name what can cause inner ear and cochlear disorders.

Back 23

Embryonic malformations, infections, noise induced hearing loss, inherited conditions, congenital infections (e.g. rubella, sylphillis), acquired viral, fungal, and bacterial infections, meningitis, herpes, mumps, and ototoxic drugs.

Front 24

What are the two branches of the auditory nervous system of the VIII nerve which carry the electrical sound impulses from the cochlea to the brain?

Back 24

vestibular and auditory-acoustic

Front 25

What are homophenous words?

Back 25

Words that look the same on the lips (e.g., mop/pop)
