What is localization?
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
What is lateralization?
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
What are the two primary localization cues?
Temporal/phase disparity and Intensity disparity
Frequency disparity and Intensity disparity
Frequency disparity and Temporal/phase disparity
What is the main assumption of temporal/phase disparity (interaural temporal (phase) difference) ?
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
Ongoing phase disparity: the (a) between ears provides information about which (b) leads
(a) phase relation, (b) tone
(a) frequency relation, (b) tone
(a) phase relation, (b) frequency
(a) frequency relation, (b) frequency
With (a) frequencies the sound wave is longer, therefore (b) to tell which tone's phase leads the other
(a) low, (b) easier
(a) high, (b) easier
(a) low, (b) harder
(a) high, (b) harder
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.
(a) 750-1000Hz, (b) aproximately
(a) 750-1000Hz, (b) greater than
(a) 500-750Hz, (b) approximately
(b) 500-750Hz, (b) greater than
It is possible to use phase cues up to what?
700Hz
1000Hz
700 mel
1000 mel
Phase disparity cues are most useful for frequencies that have (a) wavelengths compared to head size
long
short
equal
What is the main assumption of intensity disparity (interaural intensity difference)?
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
(a) sound tends to be reflected rather than wrapping round the head
high frequency
low frequency
high intensity
low intensity
Low-frequency pure tones primarily use (a) whilst high-frequency tones primarily use (b)
(a) phase disparity, (b) intensity disparity
(a) intensity disparity, (b) phase disparity
(a) intensity disparity, (b) intensity disparity
(a) phase disparity, (b) phase disparity
