1. What is the primary function of the outer ear?
A. Convert neural signals into sound
B. Collect and funnel sound toward the eardrum
C. Maintain balance
D. Produce auditory nerve impulses
Correct Answer: B. Collect and funnel sound toward the
eardrum
Rationale: The pinna and ear canal collect, direct, and slightly
amplify sound before it reaches the tympanic membrane.
2. Which structure separates the outer ear from the middle
ear?
A. Cochlea
B. Stapes
C. Tympanic membrane
D. Eustachian tube
Correct Answer: C. Tympanic membrane
Rationale: The tympanic membrane, or eardrum, forms the
boundary between the external auditory canal and middle ear.
,3. Which three bones make up the ossicular chain?
A. Cochlea, vestibule, semicircular canals
B. Malleus, incus, stapes
C. Pinna, canal, cochlea
D. Tympanum, cochlea, stapes
Correct Answer: B. Malleus, incus, stapes
Rationale: These three ossicles transmit and mechanically
amplify vibrations from the eardrum to the inner ear.
4. Which is the smallest bone in the human body?
A. Malleus
B. Incus
C. Stapes
D. Hyoid
Correct Answer: C. Stapes
Rationale: The stapes is the smallest human bone and transfers
vibration into the cochlea through the oval window.
5. What is the primary sensory organ for hearing?
A. Organ of Corti
B. Eustachian tube
C. Pinna
D. Auditory canal
Correct Answer: A. Organ of Corti
Rationale: The Organ of Corti contains sensory hair cells that
convert mechanical vibrations into neural activity.
,6. Which part of the inner ear is primarily responsible for
hearing?
A. Cochlea
B. Semicircular canals
C. Utricle
D. Saccule
Correct Answer: A. Cochlea
Rationale: The cochlea contains the structures responsible for
converting sound vibrations into neural signals.
7. Which structure primarily contributes to balance?
A. Cochlea
B. Semicircular canals
C. Tympanic membrane
D. Auditory canal
Correct Answer: B. Semicircular canals
Rationale: The semicircular canals detect rotational movement
and are part of the vestibular system.
8. What unit is commonly used to express frequency?
A. Decibel
B. Hertz
C. Pascal
D. Volt
Correct Answer: B. Hertz
Rationale: Hertz (Hz) represents cycles per second and is used
to measure sound frequency.
, 9. What does frequency primarily determine in the perception
of sound?
A. Loudness
B. Pitch
C. Distortion
D. Direction
Correct Answer: B. Pitch
Rationale: Higher frequencies are generally perceived as
higher-pitched sounds, while lower frequencies are perceived
as lower-pitched.
10. What does sound intensity primarily relate to perceptual
loudness?
A. Frequency
B. Wavelength
C. Amplitude
D. Phase
Correct Answer: C. Amplitude
Rationale: Greater sound-wave amplitude generally
corresponds to greater sound pressure and perceived loudness.
11. What unit is commonly used to express sound level?
A. Hertz
B. Decibel
C. Ohm
D. Watt-hour
