More about moose calls, vibration and sound

If you liked the Moose Call project, you might also like another quick and easy sound project that turns a straw into a reed instrument (saxophones, clarinets, snake charmer's horns, harmonicas and duck calls are all reed instruments). To go to the introduction page, click here.

 

Here is a page from the howstuffworks people about sound. Although the page is a bit cluttered with advertising, I really like the animation they have of a bell ringing. It shows how air molecules collide against each other to create a spreading shock wave to our ears. It's a more interesting way to begin to understand sound than still pictures. http://www.howstuffworks.com/hearing.htm

 

Here is a product which is very similar to the Moose Call. However, instead of a string there is a "tape" with very precise grooves (similar to LP record groves--before CDs) that create words when you pull the string. The phrases are hard to understand. I found "happy new year" to be the easiest to understand. When you go to this page, type "talking tapes" in the search box.
