AUDIOLOGY TEST 1 QUESTIONS WITH
COMPLETE ANSWERS { GRADED A+}
What does an Audiologist do? - ✔✔• Prevention of hearing loss (monitoring
school/industries programs)
• Identification of hearing loss (screening)
• Evaluations (hearing and balance assessments)
o Balance = vestibular system (semicircular canals)
• Selecting and dispensing hearing aids
• Habilitation & rehabilitation of H impaired (90% of the job)
o Habilitation is educating/counseling those who are born deaf
o Rehabilitation is educating/counseling those who became deaf
Among older adults, hearing loss is related to... - ✔✔• Poor health
• Decreased physical activity
,• Depression
• Isolation
What are the two most prevalent Audiologist jobs? - ✔✔• Medical and
Dispensing/Rehabilitative Audiologists
o ENT/Physician's office and Private Practice
What are the 5 employment settings for Audiologists? - ✔✔• Medical
• Education
• Pediatric
• Dispensing/Rehabilitative
• Industrial
How do we hear? - ✔✔Sound is captured by the pinna, goes down the ear canal,
hits the ear drum (tympanic membrane), sound pressure waves set the ear drum in
motion, then the 3 ossicle bones of the incus, malleus, and stapes moves in the oval
window of the inner ear, the fluid in the inner ear then gets set into motion, and the
basilar membrane gets moved and the tectorial membrane is moved the opposite
way, then the hairs send neural impulses to the auditory nerve.
The middle ear is an _____ filled cavity - ✔✔air
,What does the Eustachian Tube do? - ✔✔equalizes pressure on both sides of the
eardrum
What are the properties/functions of the middle ear? - ✔✔• To transmit sound
from the tympanic membrane to the cochlea
• Impedance matching transformer
o Energy transfer from air filled outer and middle ear space to fluid filled inner ear
space
o Provides about a 30dB boost in sound energy to account for the reduction in
energy for sound traveling from an air filled medium to a fluid filled medium
What are the two middle ear muscles? (used for impedance) - ✔✔• The tensor
tympani and the stapedius muscle
o The two muscles contract and the ear drum stiffens which allows for the sound to
get reflected off the eardrum; protects the inner ear!
The cochlea is ________ arranged! - ✔✔tonotopically
-Lower frequencies are located towards the apex and higher tones are located
towards the base
, -Travelling wave depending on it's frequency will peak on a certain point on the
Basilar membrane
The inner ear is ____ filled (cochlear) - ✔✔FLUID
What is the vestibular labyrinth? - ✔✔• It consists of three semicircular fluid/cell
filled canals that connect to one another and control your sense of balance.
o Semicircular canals
The sensory organ of hearing is the __________, which sits on the ___________ -
✔✔Organ of Corti; basilar membrane
What is the pathway of sound? - ✔✔• Outer ear, Middle ear, Inner ear, Auditory
Nerve (8th cranial nerve)
• Acoustic energy, mechanical energy, electro-chemical energy, electrical energy
Define air conduction - ✔✔(how we hear sounds normally) sound travels from
the outer ear to the middle ear and into the inner ear
Define bone conduction - ✔✔sound bypasses the outer and middle ear, and
stimulates the cochlea in the inner ear directly
What is Ototoxicity? - ✔✔Hearing loss caused by medications
