B)amplitude
C)pitch
D)rarefaction

Question

Quizplus · Accepted Answer

Frequency theory suggests that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus allowing us to perceive pitch. As the frequency of a tone rises, the nerve impulses traveling up the auditory nerve also rise in frequency, which is how our brain processes high-pitched sounds. Loudness (A) is determined by the intensity or amplitude of a sound wave, not its frequency. Amplitude (B) refers to the height or strength of a sound wave and corresponds to perceived loudness, not pitch. Rarefaction (D) refers to the less-dense regions of a sound wave and does not have a direct correlation with pitch perception.
