AUDIOLOGY MIDTERM EXAM
QUESTIONS WITH 100% VERIFIED
ANSWERS
\.What is air conduction (AC)? - ANSWERS✔-Tests entire auditory pathway TM -
ME - Cochlea - 8th nerve
\.What does AC measure? - ANSWERS✔-Total hearing loss (conductive +
sensorineural). OE- ME- IE- 8th nerve - auditory brain stem - 7th nerve on both
sides - stapedius muscle contracts on both sides - occicular chain contracts- TM
stiffens
\.What is bone conduction (BC)? - ANSWERS✔-use bone oscillator behind mastoid
bone, bypassing outer/middle ear
\.What does BC measure? - ANSWERS✔-Sensorineural hearing only
\.What is the air-bone gap (ABG)? - ANSWERS✔-Difference between air
conduction and bone conduction thresholds
\.Where does conductive hearing loss occur? - ANSWERS✔-Outer or middle ear
, \.What are common causes of conductive hearing loss? - ANSWERS✔-Fluid,
earwax, perforation, otosclerosis
\.Where does sensorineural hearing loss occur? - ANSWERS✔-Inner ear (cochlea
or auditory nerve)
\.What are common causes of sensorineural hearing loss? - ANSWERS✔-Aging,
noise exposure, genetics
\.What is mixed hearing loss? - ANSWERS✔-Combination of conductive and
sensorineural hearing loss
\.What is the normal hearing range for adults? - ANSWERS✔-0-25 dB HL
\.What is a slight hearing loss range for children? - ANSWERS✔-12-25
\.What is considered mild hearing loss? - ANSWERS✔-26-40 dB HL
\.What is considered moderate hearing loss? - ANSWERS✔-41-55 dB HL
\.What is considered moderately severe hearing loss? - ANSWERS✔-56-70 dB HL
\.What is considered severe hearing loss? - ANSWERS✔-71-90 dB HL
