Ch 10: Hearing in Environ

Question 1

Compare and contrast azimuth, elevation, and distance localization.

Answer 1

a- in front of us, to the left/right of us (horizontal); e: above/below us (median); distance

Question 2

Compare and contrast interaural level differences and interaural time differences.

Answer 2

between ears, acoustic shadow (best for high proximity and high frequency sounds); diff in time that sound arrives in both ears due to size of head

Question 3

Describe the “cone of confusion.”

Answer 3

objects will produce the same level and time diff even though they’re not in the same location (ex: can’t diff b/n front and behind)

Question 4

Describe spectral shape cues.

Answer 4

work best for sounds that have a broad frequency spectrum

Question 5

What cues are used for distance?

Answer 5

sound level; “blurring” (reduction in sound level over distance greater for high frequencies)
