Question

Quizplus · Accepted Answer

Pitch refers to the frequency of sound waves, which is determined by the number of wave cycles per second.

Answer: D
 The elastic membrane in the cochlea, known as the basilar membrane, creates pressure waves in the cochlear fluid to stimulate hair cells and transduce sound waves into neural signals.

Answer: G
 Pitch can be described in terms of the peak height and valley depth of sound waves, which correspond to the amplitude of the wave.

Note: None of the other options directly relate to the concept of pitch.
