Verified/ latest Version (2024/2025)
What are the four features of the scientific method? - ✔✔empirical
deterministic
predictive
parsimonious
What does empirical mean? - ✔✔based on data
What does deterministic mean? - ✔✔obey physical laws
What does predictive mean? - ✔✔show what will happen
What does parsimonious mean? - ✔✔use the simplest explanation possible
Why do SLPs use technology in clinical practices? - ✔✔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? - ✔✔pitch is
subjective to the listener
frequency is objective and can be measured
How do waveforms differ as frequency goes up or down? - ✔✔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? -
✔✔Loudness is subjective and cannot be measured
, Intensity is objective and can be measured by equipment
What are the units of measurement for intensity? - ✔✔HL
SPL
What is difference limens? - ✔✔the smallest detectable change (DL)
What is the difference limens for frequency? - ✔✔DLs become larger as the frequency
decreases
What is the difference limens for intensity? - ✔✔DLs become larger as the intensity
decreases
How does a complex periodic sound change when the fundamental is removed or muted? -
✔✔when removed, the timbre (quality) differs, but the pitch is perceived as the same
How many semitones are in one octave? - ✔✔12
What is a voice range profile (VPR)? - ✔✔a visual representation of a person's the amplitude
and fundamental frequency range
How is the VRP computed and what does it show? - ✔✔x-axis represents the fundamental
frequency range
y-axis represents the amplitude
What is the root mean square amplitude? - ✔✔refers to the square root of the mean of the
squares of the value
What is the inverse square law? - ✔✔it states that intensity is inversely proportional to the
square of the distance from the source
