- ✔✔SLPs' use of technology [why do we use it clinically? how can
acoustics help?
What does it mean for science to be "empirical"? - ✔✔Science being
empirical means it is based on observable measurement/data
What does it mean for science to be "replicable"? - ✔✔Findings need to be
able to be tested through experiments and findings need to be able to be
repeated by other scientists.
It helps us overcome listener bias (e.g. sometimes SLPs might hear what
we want to hear, especially if they want their client to get better!) -

, -Acoustics can help us understand movements of the vocal folds and vocal
tract (+ how they might change over time - ✔✔SLPs' use of technology

-Pitch perception - ✔✔subjective perception, relies on perceptual
judgements, listener ratings
-Frequency measurement - ✔✔objective, based on measuring how fast
changes in air pressure occur (i.e. number of cycles of movement per
second).
You can measure frequency in waveforms: as frequency increases, the
crests/peaks of the waves get closer together in time; as frequency
decreases, the crests/peaks of the waves get further apart in time. - ✔✔-
Frequency measurement
-Loudness perception: - ✔✔perceptual, judged by a listener, cannot be
measured by equipment, not correct or incorrect
-Acoustics: - ✔✔sound pressure changes are related to the height of a
waveform (i.e. how high is the change in air pressure). These are typically
