CMU CSD 331 (AUDIOLOGY
CONCEPTS) FINAL EXAM ACTUAL
QUESTIONS AND CORRECT ANSWERS
Otolaryngologist - CORRECT ANSWERS✅✅Ear, nose, and throat doctor
Neurotologist - CORRECT ANSWERS✅✅Specializes in the diagnosis, treatment, and
management of disorders of the brain and nervous system.
Audiologist - CORRECT ANSWERS✅✅Evaluates, diagnoses, and treats hearing and
balance/vestibular disorders.
Hearing Aid Dispenser - CORRECT ANSWERS✅✅Person with no formal training in
hearing processes, gives hearing exams, and fits people with hearing aids.
Development of Audiology - CORRECT ANSWERS✅✅Hearing tests were performed by
physicians until around WWII, when soldiers would come home with hearing loss caused by
high-level noise exposure from weaponry.
Raymond Carhart - CORRECT ANSWERS✅✅The 'Father of Audiology', founded the field
of audiology and recognized the limitations of setting the goal of having a Master's Degree to
become an Audiologist.
Georg von Bekesy - CORRECT ANSWERS✅✅Researched function of the cochlea,
tonotopic organization of the basilar membrane, base- high freq. apex- low freq. Won the
1961 Nobel prize in physiology and medicine.
James Jerger - CORRECT ANSWERS✅✅Worked under Carhart, developed many test and
rehab procedures, founding member of AAA, author or co-author of over 300 publications.
Marion Downs - CORRECT ANSWERS✅✅Champion of Pediatric Audiology, led the
movement for universal newborn hearing screening.
, Physical Event of Sound - CORRECT ANSWERS✅✅A wave of pressure fluctuations in a
medium.
Psychological Phenomenon of Sound - CORRECT ANSWERS✅✅The subjective
experience of a wave, including its perceived loudness, pitch, and timbre.
Wave Cycle - CORRECT ANSWERS✅✅A wave's peak to peak or trough to trough.
Frequency - CORRECT ANSWERS✅✅The number of complete sine waves that occur in
one second. Measured in Hertz (Hz). Example: 40 sine wave cycles = 40 Hz.
Period - CORRECT ANSWERS✅✅The duration (in seconds) of one cycle of vibration.
Amplitude/Intensity - CORRECT ANSWERS✅✅The distance a mass moves (or is
displaced) from its resting point. Height of crest or depth of trough of a wave. Measures
loudness.
Phase - CORRECT ANSWERS✅✅Stage that is given at a point in time 0, 90, 180.
In Phase - CORRECT ANSWERS✅✅Starting phase is the same and move together.
Out of Phase - CORRECT ANSWERS✅✅Starting phase is not the same.
Sound Intensity - CORRECT ANSWERS✅✅Indicates how many sound particles are
transmitted from the source to the surrounding area.
Sound Pressure - CORRECT ANSWERS✅✅Tells how much the sound is compressed or
rarefied. It represents the strength of sound and is the oscillation of air molecules produced by
a vibrating sound source.
Sound Pressure Doubling - CORRECT ANSWERS✅✅When the sound pressure increases
x10, the sound pressure level increases by 20 dB.
