How does sampling rate relate to playback quality, file size, frequencies saved in recording? - The
higher the sampling rate, the bigger file size is needed and the higher quality you will have
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
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
What are the four features of the scientific method? - empirical
deterministic
predictive
parsimonious
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
