ACTUAL Exam Questions and CORRECT
Answers
What are the four features of the scientific method? - CORRECT ANSWER - empirical
deterministic
predictive
parsimonious
What does empirical mean? - CORRECT ANSWER - based on data
What does deterministic mean? - CORRECT ANSWER - obey physical laws
What does predictive mean? - CORRECT ANSWER - show what will happen
What does parsimonious mean? - CORRECT ANSWER - use the simplest explanation
possible
Why do SLPs use technology in clinical practices? - CORRECT ANSWER - to overcome
listener bias
to describe severity objectively
to demonstrate treatment efficacy (track progress)
to provide biofeedback
What is the difference between pitch perception and frequency measurement? - CORRECT
ANSWER - pitch is subjective to the listener
frequency is objective and can be measured
, How do waveforms differ as frequency goes up or down? - CORRECT ANSWER - higher
frequency wavelengths appear closer together with more frequency over a period of time than
lower frequencies
What is the difference between loudness perception and intensity measurement? - CORRECT
ANSWER - Loudness is subjective and cannot be measured
Intensity is objective and can be measured by equipment
What are the units of measurement for intensity? - CORRECT ANSWER - HL
SPL
What is difference limens? - CORRECT ANSWER - the smallest detectable change (DL)
What is the difference limens for frequency? - CORRECT ANSWER - DLs become larger
as the frequency decreases
What is the difference limens for intensity? - CORRECT ANSWER - DLs become larger
as the intensity decreases
How does a complex periodic sound change when the fundamental is removed or muted? -
CORRECT ANSWER - when removed, the timbre (quality) differs, but the pitch is
perceived as the same
How many semitones are in one octave? - CORRECT ANSWER - 12
What is a voice range profile (VPR)? - CORRECT ANSWER - a visual representation of a
person's the amplitude and fundamental frequency range
How is the VRP computed and what does it show? - CORRECT ANSWER - x-axis
represents the fundamental frequency range
