COMD 5070 UPDATED EXAM QUESTIONS
AND CORRECT ANSWERS
●● 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?
