Human Voice vs Tuning Fork (Lim Hao Yang and Shawn Lim)

Top: human voice (Wave A); below: tuning fork (Wave B)

The shape of Wave B is more complex as compared to Wave A, whereas Wave A is more pure. Hence we can conclude that the human voice consists of multiple pitch and tones.

The amplitude of Wave B is smaller than that of Wave A. Hence, we can conclude that the sound made by the tuning fork is louder than that made by the human.

The frequency of Wave B is less than the frequency of Wave A, hence the human voice created a lower pitch as compared to the tuning fork.
