ASLP 3030 ACTUAL UPDATED Exam
Questions and CORRECT Answers
What does it mean for science to be "empirical" and "replicable"? - CORRECT
ANSWER - 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?) - CORRECT
ANSWER - 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) - CORRECT ANSWER - 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) - CORRECT ANSWER - 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.
Sound pressure is measured in micro pascals and may be expressed in dB SPL.
-Intensity measurement = measured in dB, IL, and SPL
- Sound pressure = units of pressure both measured with a sound level meter
