COMD 5070 exam 1 2025 Questions and
Answers
4 features of the scientific method - --Answer --1) Science is empirical- we
collect data and interpret it (based on data)
2) Science is Deterministic - Things are not random. Because of cause and effect,
we can draw generalizations from the data that we have and extrapolate
3) Science is predictive - if you do this, then that will happen.
4) Science is parsimonious - use the simplest explanation possible, try to describe
things in economical terms so we can understand it. Use the simplest terms
possible, but no simpler.
Why do SLPs use technology - --Answer --1) Overcome listener bias -
computer isn't influenced by what it has heard before. It is a consistent, reliable
measure.
2) Describe severity objectively - standardizes measures of speech
3) Track progress over time - helps demonstrate treatment efficacy

, 4) Helps to comply with ASHA's focus on EBP - provides hard data to measure
rather than just gut feelings about progress based on experience.
5) Biofeedback- computer display in real time - ex: visipitch shows intonations on
screen in real time, shows them progress as they speak, better than playing back a
recording.
How can acoustics help? - --Answer --acoustics can tell us a lot about what
is going on that can't be seen. Acoustics is a way of using quantitative measures to
to describe a physical phenomenon, rather than relying on our human impressions
Frequency - --Answer --how frequently a waveform repeats. Measured in Hz
(cycles per second). Within the same window length, a higher frequency sound
wave will show more repetitions than a lower frequency sound wave
simplest sound - --Answer --pure tone (sine wave)
Pitch - --Answer --the subjective measure of frequency; you cannot measure
pitch with an instrument. You can have people match pitch perception to
frequencies.
Intensity - --Answer --amplitude or size of a sound.Adjusting volume, is
adjusting the physical intensity of sound.
