azimuth, elevation, and distance

Question 2

Interaural time difference is based on the:

Answer 2

time difference between a sound reaching the left and right ears (effective cue for localization at low-frequency sounds)

Question 3

Interaural level difference is based on the:

Answer 3

difference in sound pressure level of the sound reaching the two ears

Question 4

acoustic shadow is the disruption of high frequency sound waves, resulting in a _______ of intensity on the far side of the head

Answer 4

decrease

Question 5

narrowly tuned ITD neurons are used in:

Answer 5

specificity coding

Question 6

broadly tuned ITD neurons used in:

Answer 6

distributed coding

Question 7

auditory scene analysis is the process by which:

Answer 7

the stimuli produced by each of the sources in the scene are separated into separate perceptions

Question 8
