B)  mixed frequencies. 
C)  intermediate frequencies.

Question 3

Guttman, Gilroy, and Blake (2004) had people view a brief visual sequence in which the light and dark bars of a grating switched positions rapidly but unpredictably over time. This pattern of switches created a visual rhythm that uniquely defined each sequence. People viewed two successive visual rhythm sequences and judged whether or not the two were identical. Guttman and associates found

Accepted Answer

A)  poorer performance when the visual rhythms were accompanied by an unrelated auditory rhythm. 
B)  poorer performance when the visual rhythms were accompanied by a related auditory rhythm. 
C)  better performance when the visual rhythms were accompanied by an unrelated auditory rhythm. 
D)  better performance when the visual rhythms were accompanied by a related auditory rhythm.

B)  ostosclerosis. 
C)  presbycusis. 
D)  none of these

Question 5

The place theory of perception is NOT supported by which of the following?

Accepted Answer

A)  Damage to the basilar membrane causes a loss of ability to hear only a certain limited set of frequencies. 
B)  Stimulation of the basilar membrane produces different pitches in association with the specific location stimulated. 
C)  Low frequencies (below 1,000 Hz) produce a broad pattern of displacement of the basilar membrane. 
D)  None of these support place theory.

Question 6

The difference between broadband noise (BBN) and bandpass noise (BPN) is that

Accepted Answer

A)  BBN is loud, whereas BPN is not.

D)  contour matching.

Question 8

Auditory looming is

Accepted Answer

A)  a steady increase in intensity of sound as a sound source approaches. 
B)  a tendency for mid-range frequencies to be louder than high and low frequencies. 
C)  the ability to pick out a particular speaker in a noisy environment with many other speakers. 
D)  all of these

Question 9

How many positions are there in the horizontal plane where the interaural sound intensity difference is zero?

Accepted Answer

A)  one 
B)  two 
C)  three 
D)  four

Question 10

Indicating how loud a sound is by assigning it a number proportional to its loudness is called

Accepted Answer

A)  digitation. 
B)  loudness matching. 
C)  magnitude estimation.
