1. Objective psychophysics - CORRECT ANSWER there is definitely "correct" or
"incorrect" answer
2. During the calibration of the MAP procedure, 0.5 volts of input to the
headphone produced 100 micropascals of sound pressure measure by the
microphone inside the manikin. During testing, 0.1 volts of input to the
headphone produced a sound pressure that was just detectable for the
listener. What was the hearing threshold in micropascals for the listener? -
CORRECT ANSWER 20 micropascals
3. what is the dynamic range of hearing? - CORRECT ANSWER from the softest
sound level one can detect to the loudest sound level one can tolerate
4. If the power remains the same and the duration increases by a factor of
100, what happens to the sound's energy - CORRECT ANSWER energy
increases by 20 dB
5. If the Weber's Fraction for frequency discrimination is 0.1, and the base
frequency is 900 Hz, what is the end in Hz for discriminating a difference in
frequency from 900 Hz? - CORRECT ANSWER 90 Hz
,6. What is the approximate Weber's Fraction in dB for intensity
discrimination? - CORRECT ANSWER 1 dB
7. What is masking? - CORRECT ANSWER the threshold for detecting a sound
is increased due to the presence of another sound
8. If a 1400 Hz masker is masking a 2803 Hz signal, what perceptual
phenomenon occur? - CORRECT ANSWER beatings between the signal and
the second harmonic of the masker
9. The turning curve may indicate the shape of the internal auditory filter
centered on? - CORRECT ANSWER signal frequency
10.If a 2 dB signal to noise ratio is required for tonal signal detection in the
presence of a broadband noise within a spectrum level of 50 dB, what is the
required signal-to-noise- ratio for tonal signal detection if the spectrum
level of the broadband noise is increased by 10 dB? - CORRECT ANSWER 2
dB
11.What is a critical band? - CORRECT ANSWER a frequency band centered on
the signal frequency, in which the masker can effectively mask the signal
12.What is the difference between backward and forward masking? - CORRECT
ANSWER signal is before masker in backward masking, while masker is
before signal in forward masking
, 13.What is the theory used to explain localization in the azimuth plane? -
CORRECT ANSWER duplex theory of localization
14.Minimal audible angle is smallest at? - CORRECT ANSWER 0 degree azimuth
15.In the precedence effect, what is taking precedence? - CORRECT ANSWER
the source sound takes precedence over reflected sound in determining
source location
16.What does M(pie)So refer to? - CORRECT ANSWER signal is inter aurally in
phase, masker is inter aurally 180 degrees out of phase
17.If a 68 dB SPL sound is judged equally loud to a 50 dB SPL, 1000 Hz tone,
how loud is the 68 dB SPL sound? - CORRECT ANSWER 50 phons
18.What is a sone - CORRECT ANSWER a measure of loudness
19.If a sound consists of the following spectral componentsL 375 Hz, 500 Hz,
625 Hz, 750 Hz, and 875 Hz. What is likely to be the perceived pitch in Hz? -
CORRECT ANSWER 125 Hz
20.Can temporal periodicity and spectral structure explain all of the
experimental data on pitch perception of complex sound? - CORRECT
ANSWER no
