Question 4

Free

Multiple Choice

Interaural level differences are a cue to auditory localization because the _____ .

Choose correct answer/s

medium through which the sound travels can be air, liquid, or solid

acoustic shadow is more likely to occur in an enclosed space than outdoors

Question 10

Multiple Choice

Hofmann et al. had participants wear artificial pinnae for about three weeks. What did they find

Choose correct answer/s

Participants could not adapt to wearing the artificial pinnae.?

Participants adapted in about 19 days, but then could not accurately localize sounds when they removed the artificial pinnae.

Participants adapted in about 19 days, and then could accurately localize sounds when they removed the artificial pinnae.

Participants could not localize sounds along the azimuth with the new pinnae, but could localize sounds along the elevation coordinate after 3 days of adaptation.
