Question

1. Search the internet for a story or article that relates to sound. When you find something that interests you describe what you learned about sound and try to post a related picture or figure. Note this can be anything related to sound from technical to cultural. It can be a video but you must describe the results and post the video if you do so. I'm leaving this a bit open so we get some interesting posts. Try to keep it to no more than 500 words.

Answer 1

There are many aspects of sounds we get to see in our daily life. Let's take an musical instrument say guitar. Every property of sound can be seen on it. We can see how by holding the strings at different position gives us the sound at different frequencies. Also how the thickness of the strings affects it's pitch. The body of the guitar is a Helmholtz resonator that amplifies the sound of the strings. The position of the frets are carefully made so that it satisfies the condition for the formation of a standing wave that gives us a beautiful sound and not any noise.
