CMU CSD 331 (AUDIOLOGY CONCEPTS) FINAL EXAM 2025
WITH ACCURATE SOLUTIONS
1. In a sound stimulus, the number of cycles that occur in a second is known
as:
Amplitude
None of the above
Frequency
Timbre
2. Describe the significance of frequency in the context of hearing and
audiology.
Frequency indicates the duration of sound waves and is unrelated
to pitch.
Frequency is the measure of sound intensity and is expressed in
decibels.
Frequency, measured in Hertz, refers to the number of cycles
per second and is crucial for determining pitch in sound
perception.
Frequency is the amplitude of sound waves and affects loudness.
3. Which of the following is a function of the central auditory nervous
system?
transduction
impedance matching
protection
information processing
,4. The presence of TEOAEs is suggestive of all of the following except
, normal auditory nerve function
normal out ear function
normal outer hair cell function
normal middle ear function
5. Hearing loss resulting from the use of ototoxic drugs is:
Retrocochlear
Sensorineural
Conductive
Mixed
6. In a scenario where a newborn is screened for hearing but has a delayed
onset hearing loss, what follow-up action should be prioritized?
Schedule a hearing test for the parents.
Provide immediate intervention services.
Conduct additional testing after a specified period.
Ignore the initial screening results.
7. Describe how the Speech Detection Threshold is determined and what it
indicates about a patient's hearing ability.
It is determined by evaluating the patient's ability to repeat words,
indicating language proficiency.
It is determined by finding the lowest level at which speech can
be detected 50% of the time, indicating the patient's speech
threshold.
It is determined by measuring the maximum volume a patient can
tolerate, indicating potential hearing loss.
, It is determined by assessing the clarity of speech at various
volumes, indicating overall hearing ability.
8. Which of the following measures the ongoing electrical activity of sound
that is present in the brain and is used for infants from birth to 6 months
of age or noncooperative individuals?
Otoacoustic emissions (OAE)
Auditory brainstem response (ABR)
Audiometry
Tympanometry
9. An audiologist typically
Diagnoses hearing loss and its causes
Teaches sign language
Administers voice assessment
Administers cognitive assessment
10. Who got the Nobel Prize in physiology or medicine for describing the
passive tonotopy in the cochlea?
Eric Kandel
David Hubel and Torsten Wiesel
Róbert Bárány
Georg von Békésy
11. What are TEOAs commonly referred to as?
Cochlear echos
Hearing aids
Sound waves
