a. retinal disparity
b. pitch increase
c. sensitization
d. subliminal stimulation
Answer:
This is an example of C. sensitization.

There was, however, an alteration in people's perception of the sound, and that is due to a process known as sensitization. Sensitization happens when a certain stimulus becomes more effective because of repetition or continuation. That is, because people kept on listening to the sound, even though it was low, they were able to hear it after a while.
