COMD 5070 COMPLETE QUESTIONS AND
ANSWERS 2026 TEST PAPER GRADED A+
◉ Why do SLP's use technology?. Answer: 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. Answer: 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. Answer: a perceptual characteristic judged
by a listener, can NOT be measured by equipment, psychophysical
scale links loudness to intensity
◉ Intensity. Answer: is measured in dB and intensity = amplitude
◉ IL. Answer: Intensity Level
◉ SPL. Answer: Sound Pressure Level
, ◉ HL. Answer: Hearing Level
◉ Loudness is measured with. Answer: a sound level meter (NO
SUCH THING AS A LOUDNESS METER)
◉ difference limens (DLs). Answer: smallest detectable change in
frequency, DLs increase with stimulus frequency, as intensity
decreases DLs become larger
◉ How many semitones are in one octave?. Answer: 12
◉ Octave. Answer: 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?. Answer: 24
◉ voice range profile (VRP). Answer: 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). Answer: 1. squaring makes all of the
values positive 2. Get the average of the squared values 3. Get the
square root of the average
