Question

Mina has excellent hearing. She can hear musical notes and electronic chimes that her friends all miss. Mina's _____ for sounds seems to be lower than that of her friends.

a. difference threshold
b. jnd
c. absolute threshold
d. minimal tolerance

(I don't understand this at all)

Answer 1

Difference Threshold? If she can hear sounds at lower frequencies then her friends then I would assume her difference threshold starts at a lower point and would end at a lower point then her friends. I'm not sure, this is just my best guess.
