COMD 5070 EXAM 1 QUESTIONSEmpirical, deterministic, predictive, parsimonious - answer- the scientific method is
_______, ________, ________, and ________
Empirical - answer- science is ________: based on data- we collect data and then
interpret it; we have to make sense of the behavior that we're trying to understand
Deterministic - answer- science is __________: things obey physical laws; not random
in terms of cause and effect, and can draw generalizations from data that we can
extend on to other situations we have not yet experienced
Predictive - answer- science is ________: if a given phenomenon occurs, it can
influence another one; represents cause and effect relationships
Parsimonious - answer- science is _________: uses the simplest explanation versus
making it unnecessarily convoluted
Listener bias, severity objectively, progress over time, ebp, biofeedback - answer- why
do slps use technology?
-overcome _________ _______
-describe ________ _________
-track ________ _______ _______
-asha's focus on ___________
-provide ___________ to the client
Acoustics - answer- ____________ can help by telling us how the larynx is operating or
how articulators are moving; measures speech production through microphone readings
Kinematics - answer- ______ is the study of speech movements
Aerodynamics - answer- __________ describes the pressures and flows and
resistances involved in regulating our breath stream as we speak
Electromyography - answer- __________ is the measure of electrical activity in muscles
as they are activated
Speech perception - answer- ________ __________ is how the brain interprets sounds
Complex tone - answer- a _________ ________ involves multiple sine waves together,
blended, with the fundamental frequency as the lowest frequency component
Pitch - answer- _________ is the subjective perception of frequency
-it cannot be measured with instruments
-listener matches perceived pitch to that of a pure tone of known frequency
, Difference limen, more, larger - answer- the frequency _______ ___________ is the
smallest detectable change in frequency that is detectable by a listener
-higher frequency sounds must differ ________ to be heard as different in pitch
-true for comfortable listening level
-as intensity decreases, dls become ____________
Fundamental frequency - answer- the _________ __________ tends to be the loudest
sounding in a complex series of sounds (e.g. Harmonics)
Harmonics - answer- __________ are periodic, integer multiples of the fundamental
frequency
Residue pitch - answer- another name for the missing fundamental phenomenon is
__________ __________
Timbre/quality, pitch, harmonic structure, calculation, simulated bass - answer- missing
fundamental:
-_______/________ is different
-_________ is still perceived as the same
-brain processes the ________ ________, by filling in the gaps through __________
-cheap audio equipment takes advantage of this phenomenon with a ________
________
Octave, 800, 200 - answer- an _________ is the doubling or halving of a frequency
E.g. If you have a 400 hz base and you went up an octave, you would reach _______
hz, and if you went down an octave you would reach _______ hz
12, nonlinear, bigger - answer- there are _______ semitones in 1 octave
-each semitone is a _________ step- each step upward is _______ than the last (about
5.9%)
-no semitones are physically identical in hz, but they sound equal in step size, because
our human perception of sound is nonlinear
Intensity, il, spl - answer- ___________ is the amplitude or 'size' of a sound
-measured in db
-based on a logarithmic scale
-the levels are measured in _____ and _____
Loudness - answer- _______ is a perceptual characteristic of intensity
-it is judged by a listener and is neither correct or incorrect
-it cannot be measured by equipment
-there is a psychophysical scale that can link it to intensity
1000, 5000, lowest, highest - answer- hearing is more sensitive at some frequencies
-lowest thresholds are from _______ to _______ hz
