Information about the interference of sound and its causes. Well-illustrated and good explanations of the concepts; part of a large hyper-textbook on various physics concepts.

An indexing page for an elaborate and in-depth hyper-textbook on various physics topics. This page indexes several others which pertain to human ability to perceive sound and recognize pitch. Introduces and explains Place Theory.

This page and the many pages which are indexed to focus on the behaviors of sound which characterize it as a wave. Reflection, refraction, interference, diffraction and more are clearly illustrated and explained.

Online physics lab experiment in which students use resonating waves inside of a closed-end air column to determine the speed of sound. The form allows students to check their answers and receive immediate feedback.

A tutorial from a hypertext physics course book that discusses reverberation. Illustrated.

Home page for a hypertext physics course. Users can access subjects ranging from the sound wave parameters that effect hearing and communication to OSHA worplace standards.

This site's entry is a discussion of diffraction and its application to acoustics and acoustical design. Exceptional illustrations and great discussion throughout.

A discussion of refraction and its application to sound waves. Using analogies, graphics and real-life applications, this page and those that accompany it explain why and when sound waves bend.

Great animations showing how sound is produced.

This lesson plan is designed to teach young children about how sound is heard in a three-step process using the Magic School Bus materials.
