Question 1
Question
What is localization?
Answer
-
The experience of sound's origin in space
-
Where the individual is in auditory space
-
Where the sound is in auditory space
-
The process of transmitting a sound in order to be located
Question 2
Question
What is lateralization?
Answer
-
The experience of sound's origin inside the head
-
The experience of sound's origin in auditory space
-
The ability to process auditory stimuli in both hemispheres
-
The experience of two or more sounds coming from different locations
Question 3
Question
What are the two primary localization cues?
Answer
-
Temporal/phase disparity and Intensity disparity
-
Frequency disparity and Intensity disparity
-
Frequency disparity and Temporal/phase disparity
Question 4
Question
What is the main assumption of temporal/phase disparity (interaural temporal (phase) difference) ?
Answer
-
The sound will reach one ear before the other, onset difference
-
The soundwave will be at a different phase when it reaches one ear than when it reaches the other
-
The temporal qualities of a sound give information about the source of the sound
-
The relationship between amplitude and pitch give information about the sound's location
Question 5
Question
Ongoing phase disparity: the (a) between ears provides information about which (b) leads
Answer
-
(a) phase relation, (b) tone
-
(a) frequency relation, (b) tone
-
(a) phase relation, (b) frequency
-
(a) frequency relation, (b) frequency
Question 6
Question
With (a) frequencies the sound wave is longer, therefore (b) to tell which tone's phase leads the other
Answer
-
(a) low, (b) easier
-
(a) high, (b) easier
-
(a) low, (b) harder
-
(a) high, (b) harder
Question 7
Question
Between frequencies of (a) time taken to complete half a wavelength is (b) the time taken to travel the head's circumference. Therefore ambiguous to which ear is receiving tone.
Answer
-
(a) 750-1000Hz, (b) aproximately
-
(a) 750-1000Hz, (b) greater than
-
(a) 500-750Hz, (b) approximately
-
(b) 500-750Hz, (b) greater than
Question 8
Question
It is possible to use phase cues up to what?
Answer
-
700Hz
-
1000Hz
-
700 mel
-
1000 mel
Question 9
Question
Phase disparity cues are most useful for frequencies that have (a) wavelengths compared to head size
Answer
-
long
-
short
-
equal
Question 10
Question
What is the main assumption of intensity disparity (interaural intensity difference)?
Answer
-
Sound will be slightly more intense in closer ear
-
Sound will be slightly more intense in farther ear
-
Sound will be slightly more intense depending on its frequency
-
Sound will be slightly less intense depending on its timbre
Question 11
Question
(a) sound tends to be reflected rather than wrapping round the head
Answer
-
high frequency
-
low frequency
-
high intensity
-
low intensity
Question 12
Question
Low-frequency pure tones primarily use (a) whilst high-frequency tones primarily use (b)
Answer
-
(a) phase disparity, (b) intensity disparity
-
(a) intensity disparity, (b) phase disparity
-
(a) intensity disparity, (b) intensity disparity
-
(a) phase disparity, (b) phase disparity
