1. Which of the following is the primary site of sound transduction in the
cochlea?
A. Tympanic membrane
B. Organ of Corti
C. Eustachian tube
D. Round window
The Organ of Corti contains hair cells that convert mechanical sound
vibrations into neural signals, making it the primary site of auditory
transduction.
2. The most common cause of conductive hearing loss in adults is:
A. Sensorineural degeneration
B. Noise exposure
C. Cerumen impaction
D. Presbycusis
Cerumen impaction blocks the external auditory canal, preventing
sound from reaching the tympanic membrane, and is a frequent
cause of conductive hearing loss in adults.
3. In pure-tone audiometry, a difference of 10 dB between ears at a
single frequency may indicate:
A. Normal hearing
B. Asymmetrical hearing loss
C. Central auditory processing disorder
D. Tinnitus
, A 10 dB or greater difference between ears at a specific frequency
suggests asymmetrical hearing loss, warranting further
investigation.
4. Which test is most appropriate for assessing middle ear function?
A. Otoacoustic emissions
B. Pure-tone audiometry
C. Tympanometry
D. Auditory brainstem response
Tympanometry evaluates the mobility of the tympanic membrane
and ossicular chain, providing objective assessment of middle ear
function.
5. Otoacoustic emissions are primarily used to:
A. Evaluate central auditory pathways
B. Screen cochlear (outer hair cell) function
C. Measure air-bone gaps
D. Determine speech discrimination scores
Otoacoustic emissions reflect the activity of outer hair cells in the
cochlea and are commonly used to screen cochlear function,
especially in newborns.
6. The Rinne test compares:
A. Air conduction to bone conduction
B. Air conduction to bone conduction in the same ear
C. Bone conduction between ears
D. Tympanic mobility
The Rinne test assesses hearing by comparing air conduction (AC)
and bone conduction (BC) in the same ear; normal hearing or
sensorineural loss shows AC > BC.
7. Which cranial nerve transmits auditory information to the brain?
A. Trigeminal nerve (CN V)
B. Facial nerve (CN VII)
C. Vestibulocochlear nerve (CN VIII)
D. Glossopharyngeal nerve (CN IX)
The vestibulocochlear nerve carries electrical signals from the
cochlea to the brainstem, enabling auditory perception.
, 8. Presbycusis typically affects which frequencies first?
A. Low frequencies
B. Mid frequencies
C. High frequencies
D. All frequencies equally
Age-related hearing loss (presbycusis) usually begins with high-
frequency loss due to degeneration of basal cochlear hair cells.
9. The primary purpose of an audiogram is to:
A. Diagnose vestibular disorders
B. Quantify hearing thresholds across frequencies
C. Evaluate speech production
D. Measure tympanic membrane compliance
An audiogram plots hearing thresholds at different frequencies,
allowing clinicians to quantify the degree and type of hearing loss.
10. Which type of hearing loss is associated with inner ear damage
but normal middle ear function?
A. Conductive
B. Mixed
C. Sensorineural
D. Central
Sensorineural hearing loss arises from cochlear or auditory nerve
pathology, with intact middle ear function.
11. Acoustic reflex testing evaluates the:
A. Outer hair cell function
B. Stapedius and tensor tympani muscle response
C. Basilar membrane movement
D. Auditory cortex activation
The acoustic reflex measures contraction of the stapedius (and
sometimes tensor tympani) in response to loud sounds, assessing
reflex pathways.
12. Which audiometric pattern is characteristic of noise-induced
hearing loss?
A. Flat loss
B. Low-frequency loss
C. Notch at 4 kHz
