Science Buddies: "Ask an Expert"

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:

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

I think these will get you started at least.

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:

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,

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
