ASLP 3030 EXAM 1 Questions and
Answers 100% Pass | Graded A+
Empirical - ✔✔based on observable measurement/data
Replicable - ✔✔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 - ✔✔- Overcome listener bias
- Consistent, reliable measurement
- Describe severity objectively
- Provide biofeedback to the client
- Track progress overtime
- Evidence-based practice
Pitch perception - ✔✔- 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 - ✔✔- 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 - ✔✔- 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 - ✔✔- 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
RMS amplitude - ✔✔- RMS = root mean square
