ASLP 3030 Exam Questions with
Complete Solutions | Rated A+
What does it mean for science to be "empirical" and "replicable"? -
Empirical: based on measurements and data (observations can be
measured with data)
Replicable: we can repeat the experiment, the ideas of an experiment can
be tested...
What does it mean for science to be "empirical" and "replicable"? -
✔✔Empirical: based on measurements and data (observations can be
measured with data)
Replicable: we can repeat the experiment, the ideas of an experiment can
be tested, findings can be replicable (done again)
SLPs' use of technology (why do we use it clinically? how can acoustics
help?) - ✔✔We use technology to get objective measurements and to
overcome listener bias because it is consistent and reliable. It can provide
feedback to clients and track progress over time. Acoustics can help us to
identify possible problems with speech, track progress, visualize what is
happening with a voice.
1) Can overcome listener bias
,2) Receive consistent, reliable measurement
3) Describe the severity of the problem objectively
4) Provides biofeedback for the client
5) Tracks progress over time
6) Evidence-based practice
Pitch perception vs frequency measurement (perceptual judgments vs
acoustics measures, how waveforms differ as frequency goes up or down)
- ✔✔Pitch perception is perceptual/ subjective, it is listener judgment.
Frequency is an objective/ acoustic measure, it is a number and cannot be
debated.
Higher frequency waveforms have peaks that look "closer together" "more
squished/ rushed"
, Lower frequency waveforms have peaks that are more spread out "think
longer"
- Frequency measurement = how frequent a waveform repeats, measured
in Hz. used to describe the physical property of the wave
- Pitch perception = how high or low the sound is to the listener, subjective
perception
How waveforms differ as frequency goes up and down: pressure changes
as time goes by
Loudness perception vs intensity measurement (perceptual judgments v
acoustic measures, what are the different units of measurement of intensity
vs sound pressure, how duration affects the loudness of brief sounds) -
✔✔Loudness is perceptual/subjective, it is a listener's judgment.
Intensity is an objective/acoustic measure, it is a number and cannot be
debated.
Intensity is measured in watts per meter squared.
