Study Questions: Auditory Pathways and Spatial Localization
1. What is interaural time difference? How does it change
with the position of the sound source? For what frequency range
is it useful, and why?
2. What is interaural level difference, and what is its
cause? For what frequency range is it useful, and why?
3. What ambiguities in sound localization are common to ILDs and
ITDs? Name two ways sound direction can be disambiguated.
4. Describe how ILDs and ITDs might be measured in the brain.
Where in the brain is the first structure in which this can and does
occur?
5. What role does the pinna play in sound localization?
