These sound files include samples of a variety of instruments playing different pitches. They should be used in conjunction with Handout 12: Seeing Sound Waves. (Coming Soon)
Activity 3B: The Science of Sound
HyperPhysics Web Site
The “Sound and Hearing” section of this Web site provides an overview of many of the topics that students will research for their Acoustipedia articles. The subsections on auditorium acoustics and sound reproduction are particularly helpful, since they contain information unlikely to be found in a high school physics textbook. http://hyperphysics.phy-astr.gsu.edu/hbase/HFrame.html
Handout 16: Acoustipedia Topics
This handout lists one or more recommended Web sites for each topic. It is available online in order to ensure that the recommended Web sites are current. (Coming Soon)
How to Set Up a Wiki
If you decide to have your students create the Acoustipedia in the form of a wiki, these sites provide free Web-based resources.
