AUD 641 Exam Questions And Answers 100%
Correct Latest 2025
T/F: Pure-tone audiometry requires a behavioral response - ANSWER True
What are some of the patient variable that influence performance on a behavioral
hearing test? - ANSWER - age and development
- neurological immaturity
- cognitive factors
- language
- attention and state of arousal
- motivation
What are objective tests? - ANSWER tests that do not require a behavioral response
from a patient
What are the purposes of objective tests? - ANSWER - used when reliable/valid
information on auditory function cannot be obtained behaviorally
- helps localize the site of auditory dysfunction in the auditory system
What are the categories of audiologic behavioral tests? - ANSWER electrophysiological
tests and electroacoustic tests
What types of tests are electroacoustic tests? - ANSWER acoustic immittance
(tympanometry/acoustic reflexes) and otoacoustic emissions
What is the cross-check principle? - ANSWER no result is accepted until it is confirmed
by an independent measure
, What are some of the strengths of electroacoustic tests? - ANSWER - do not require a
behavioral response
- results are not influenced by pt variables
- can test sedated or anesthetized pts
- provide site-specific information on auditory dysfunction
- no verbal cues necessary
- test infants and children
- reasonable test time
What are some of the weaknesses of electroacoustic tests? - ANSWER - does not
measure "hearing"
- not sensitive to dysfunction in auditory cortex
- abnormal findings does not necessarily mean hearing loss
- single measure generally provides limited info
- does not test speech perception
What is the first major anatomical structure that responds to sound waves? - ANSWER
tympanic membrane
What are the two functions of the middle ear? - ANSWER - conduct sound energy from
EC to cochlea
- transduce acoustic energy to mechanical energy
What is a transducer? - ANSWER device that changes energy from one form to another
