Exam Questions and CORRECT Answers
empirical, deterministic, predictive, parsimonious - CORRECT ANSWER - 4 features of
the scientific method.
empirical - CORRECT ANSWER - Based on data.
deterministic - CORRECT ANSWER - Obeys physical laws.
predictive - CORRECT ANSWER - If you do this... then that will happen.
parsimonious - CORRECT ANSWER - Use the simplest explanation possible.
overcome listener bias, describe severity objectively, track progress over time, ASHA's focus on
evidence based practice, provide biofeedback to the client - CORRECT ANSWER - Why
use technology?
frequency - CORRECT ANSWER - How frequently a waveform repeats itself
Hertz (Hz) - CORRECT ANSWER - Cycles per second
pure tone - CORRECT ANSWER - Simplest sound
high and low frequency - CORRECT ANSWER -
pitch perception - CORRECT ANSWER - Linked to frequency
Order on a musical scale, Subjective perception
, Cannot be measured with instruments
Listener matches perceived ______ to that of a pure tone of known frequency
frequency difference limens (DL) - CORRECT ANSWER - Smallest detectable change in
frequency. True for comfortable listening level.
increase - CORRECT ANSWER - Difference Limens _____________ with stimulus
frequency.
higher - CORRECT ANSWER - ___________ frequency sounds must differ more to be
heard as different in pitch.
larger - CORRECT ANSWER - As intensity decreases, difference limens become
__________.
missing fundamental - CORRECT ANSWER - Listen to a harmonic series
Actual ___________________ can be absent
Timbre or quality is different
Pitch still perceived as the same
Brain processes harmonic structure
Fills in the gap by calculation/interpolation
cheap audio equipment - simulated bass
Some listeners are harder to fool
12 - CORRECT ANSWER - ________ semitones in one octave
semitone - CORRECT ANSWER - Each __________ is a nonlinear step
Each step upward is bigger than the last (about 5.9% higher frequency than the one before it).
