SLPs' use of technology [why do we use it clinically? how can acoustics
help?] - ✔✔-SLPs use technology because it gives consistent, reliable
measurements.
-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!)
-Technology helps track progress over time and provide feedback to clients
-Acoustics can help us understand movements of the vocal folds and vocal
tract (+ how they might change over time)
Pitch perception vs. frequency measurement [perceptual judgments vs.
acoustic measures, how waveforms differ as frequency goes up or down -
✔✔-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.
Difference limens for frequency [what they are, how they are influenced by
frequency and intensity] - ✔✔-Difference limen: smallest detectable change
in frequency that a listener can perceive as a change in pitch
-higher frequency sounds must differ more to be heard as different in pitch
-as intensity decreases, difference limens also become large
Loudness perception vs. intensity measurement [perceptual judgments vs.
acoustic measures, what are the different units of measurement of intensity
vs. sound pressure, how duration affects the loudness of brief sounds.] -
✔✔-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
measured in dB which is a logarithmic measurement (rather than a linear
scale
dB is ______. This means that the pressure changes are not consistent
between lower dB sounds and higher dB sound - ✔✔logarthmic
