EXAM 2 PSYCHOACOUSTICS
PRACTICE TEST SET | 143
QUESTIONS | WITH COMPLETE

1 of 143
Term
103. What are the problems with the method of limits that may result
in response bias?
Give this one a try later!
Three goals:
Make soft sounds audible
Conversation level comfortable
Loud sounds tolerable
, 101. Capability is whether the patient is physically able to hear the noise, and
proclivity is what the patient is most inclined to do, not whether they can
actually do it or not.
103. Response bias:
1. Anticipation
2.Habituation: the participant will not change the response until after a
few trials have occurred
74. Monotic is presented to just one ear; diotic is the same signal presented to
both ears; and dichotic is different signals presented to each ear.

The closer the masker and the signal are in frequency, the closer
they are in _______, and the closer they are in ______ which makes...
Give this one a try later!
pitch, speed, clarity, the sound more
volume, the signal less clear
distracting
length, frequency, the noise more time, amplitude, the masker
pleasant more effective

63. True/False: Bandwidth does not play a role in loudness
perception.
Give this one a try later!
63. False; increasing the bandwidth of a noise results in an increase in
loudness if the noise is wider than the auditory filter bandwidth and
presented at moderate levels.
29. This is called phase locking; it is neurons firing in unison with the phase of
a stimulus. Each neuron has a specific job and they all work together to code
for the frequency of the stimulus.
False; a comfortable level
18. False; as you age you probably won't have present OAE's even if pure
tone thresholds are still normal.

76. How does masking affect another sound on the BM?
, Give this one a try later!
76. On the BM masking will occur 76. On the BM masking will
at a different location. amplify the signal.
76. On the BM masking will 76. On the BM masking will
cause distortion of the signal. take place at the same place
as the signal.

30. What is the point of sending a motor connection to a sensory
cell?
Give this one a try later!
30. When we think about OHCs and how they move by expanding and
contracting, this motility enhances portions of the traveling wave. So this
active mechanism gives us a sharp tuning of the TW. The tuning can be
made even sharper if we inhibit the motion of the surrounding hair cells.
So for very specific frequencies and amplitudes, a group of OHC's will
enhance the TW and they can do that by suppressing the adjacent hair
cells done by the efferent neurons.
40 dB; there won't be a loss greater than this
29. This is called phase locking; it is neurons firing in unison with the phase of a
stimulus. Each neuron has a specific job and they all work together to code for
