Believe it or not, you can feel sound! Join Gitanjali Rao, former Discovery Education 3M Young Scientist Challenge winner, as she teaches about the frequency of sound and how we perceive pitch.
While the history of “sound science” is broad and many famous scientists have made important contributions, it is Leonardi DaVinci who is generally credited with discovering that sound actually travels in waves. However, in the 17th century, Galileo made great advancements into how we perceive sound and how sound travels. He found out about frequency of sound, and how that determines pitch. If the vibrations of a sound happen far apart, the sound will have a low frequency and sound deep. If the vibrations are close together, that will create a high-pitched sound. The way that humans perceive these vibrations is something we will explore in this experiment.
