Does anyone know about the Physics of the guitar?
Or about how sound works?
And how the ear works?

Hi,

Here is a project on guitar sounds:

https://www.sciencebuddies.org/science- ... p009.shtml

Here is a project on threshold of hearing. Check out the Bibliography section for links to info on how the ear works:

https://www.sciencebuddies.org/science- ... p011.shtml

I think these will get you started at least.

Best regards,

Hi,

I've moved your question to the physical sciences forum because I think you will get more help here.

Good luck!

Hi,

Just adding on to a previous post, here are some useful sites that could help you:

http://ffden-2.phys.uaf.edu/211.web.stu ... n/main.htm
http://en.wikipedia.org/wiki/Ear
http://www.phys.unsw.edu.au/~jw/guitarintro.html

To give you a basic overview, a guitar is made up of strings that are tuned at different frequencies; plucking them generates sound waves. A sound wave is a longitudinal (back and forth) wave that relies on the air as a medium. This vibration of the air molecules causes tiny hair filaments in your ear to vibrate and at a certain threshold, give off neuronic signals that let your brain intercept the wave.

Hope this helps,

Project Question: HI. i was wondering what would be a good project to do about enviromental sciencce that is challenging, and inexpensive. I really liked the wood vs. alternatives, but it was a little hard to understand about what i could do as a project, if you cant think of anything easier, id like to compare clear cutting to thin cutting or something, i'd like something challenging so i have a good chance if you can think of a project. thank you!
Project Due Date: late january, early february(unsure exact date)
Project Status: I am just starting

hi, i'm not an expert, but i know alot about that. When you strum the sting, the string sends vibrations through the air(the molecules bumping into each other, pushing them futher on) and the whole in the guitar helps amplify the sound. This is just some, like i said i'm not an expert, but we just studied this :D
