COMD 5070 EXAM 1 QUESTIONS AND
ANSWERS GRADED A+ 2026
4 Features of the scientific method - ANS 1. Empirical - based on data 2. Deterministic - obeys
physical laws (not random) 3. Predictive - if you do this ... then that will happen 4. Parsimonious
- use the simplest explanation possible
Why do SLP's use technology? - ANS 1. overcome listener bias 2. consistent, reliable measure
3. describe severity objectively 4. track progress 5. ASHA's focus on EBP 6. provide biofeedback
to client 7. SLP need to know normal and disordered physiology 8. Need to know what the
numbers represent
Pitch perception - ANS order on a musical scale, subjective perception, can NOT be measured
with instruments, listener matches perceived pitch to that of a pure tone.
Loudness perception - ANS a perceptual characteristic judged by a listener, can NOT be
measured by equipment, psychophysical scale links loudness to intensity
Intensity - ANS is measured in dB and intensity = amplitude
IL - ANS Intensity Level

, SPL - ANS Sound Pressure Level
HL - ANS Hearing Level
Loudness is measured with - ANS a sound level meter (NO SUCH THING AS A LOUDNESS
METER)
difference limens (DLs) - ANS smallest detectable change in frequency, DLs increase with
stimulus frequency, as intensity decreases DLs become larger
How many semitones are in one octave? - ANS 12
Octave - ANS is the doubling or the halving of frequency (400Hz base, 800 Hz an octave up,
200 Hz is an octave down)
How many semitones are in two octaves? - ANS 24
voice range profile (VRP) - ANS is computed using 10 frequencies. For each frequency the
speaker produces a soft sound and a loud sound. The results are then plotted on a chart.
root mean square (RMS) - ANS 1. squaring makes all of the values positive 2. Get the average
of the squared values 3. Get the square root of the average
Inverse Square Law - ANS Intensity diminishes in proportion to the square of the distance
from the source.
