ASLP 3030 EXAM 1 2025 Questions and
Answers
Empirical - --CORRECT ANSWER--based on observable measurement/data
Replicable - --CORRECT ANSWER--is something that can be copied or
recreated. When the results of a study can be recreated, this is an example of a
study that is replicable
SLPS's use of technology - --CORRECT ANSWER--- Overcome listener bias
- Consistent, reliable measurement
- Describe severity objectively
- Provide biofeedback to the client
- Track progress overtime
- Evidence-based practice
Pitch perception - --CORRECT ANSWER--- linked to frequency, subjective
perception, cannot be measured with instruments, must be measured through
listener ratings
- The waveform is denser if a pitch is higher, otherwise its more loose

, Loudness perception - --CORRECT ANSWER--- is a perceptual characteristic,
judged by a listener, neither correct or incorrect, cannot be measured by
equipment, psychophysical scale links loudness to intensity
- measurements include: intensity level (IL) and sound pressure level (SPL)
- Duration and loudness - below 500 milliseconds, duration affects perception
(especially for durations 15-150 milliseconds), longer = more audible, ear integrates
the energy
Difference limens for frequency - --CORRECT ANSWER--- Frequency difference
limens (DL) -- smallest detectable change in frequency, DLs increase with stimulus
frequency,
- higher frequency sounds must differ more to be heard as different in pitch
- as intensity decreases, DLs become larger
Voice range profile - --CORRECT ANSWER--- voice range profile (VRP) --
measures dB range across f0 range
- Measuring vocal range: reduced loudness in some voice disorders, range of
loudness changes with pitch
- VRP data collection: 10 points between min and max f0 (linear scale - Hz
increments, log scale - in semitones) // min and max intensity at each pitch // plot
data on a chart // can calculate area // also examine shape
