Audiology Exam 3 UPDATED ACTUAL
Exam Questions and CORRECT Answers
What is the Air Conduction Pathway? - CORRECT ANSWER - the sound travels through
all three sections of the ear (outer, middle, and inner)
it is the normal route for hearing.
True or False: air conduction pathway is the most efficient method of hearing. - CORRECT
ANSWER - True
Air conduction pathology - CORRECT ANSWER - any disorder or pathology at any place
in the pathway (outer, middle, or inner) can affect air conduction hearing.
Common problems with air conduction - CORRECT ANSWER - Wax buildup (Outer ear)
Perforation of the eardrum (Middle ear)
Damage to the cochlea (Inner ear)
What is the Bone Conduction Pathway? - CORRECT ANSWER - The sound bypasses the
outer and middle ears and sends the sound directly to the inner ear.
It is not the normal route for hearing.
The sound wave doesn't travel through the ear canal and does not vibrate the eardrum or the
ossicles of the middle ear space.
Through subtle vibration of the bones of the skull, the sound is sent directly to the cochlea,
which is part of the inner ear.
, True or False: Bone Conduction is the most efficient method for hearing. - CORRECT
ANSWER - False: Bone Conduction hearing is not the most efficient method of hearing.
It takes more energy to stimulate the cochlea directly through the bones of the skull than via the
normal air conduction route.
Bone Conduction Pathology - CORRECT ANSWER - Any pathology in the inner ear
(cochlea) can affect bone conduction.
Air and Bone Conduction Relationship - CORRECT ANSWER - It is one of the most
important diagnostic tools for audiologists is to compare the results of air and bone conduction
testing in order to determine whereto the hearing loss is in the outer/middle ear system or in the
inner ear system.
How is air conduction tested? - CORRECT ANSWER - Air conduction is tested with the
client wearing earphones (testing the entire auditory system.)
How is bone conduction tested? - CORRECT ANSWER - Bone conduction is tested with
the client wearing a bone vibrator (testing only the inner ear.)
Symbols used for Air Conduction - CORRECT ANSWER - A Circle (O) represents the
right ear (Recorded in red)
A Cross (X) represents the left ear (Recorded in blue)
Conversational Speech - CORRECT ANSWER - 50 dB
What is the sensation level? - CORRECT ANSWER - The signal is being considered
relative to the client's own threshold
Example of Sensation Level - CORRECT ANSWER - Threshold: 15dB
Input source: 50dB
