COMD 5070 exam 1 study guide
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
