Students use a website to help them recognize that sound is generated in a variety of ways and from different sources. They determine that sounds vary in tone and loudness, and learn there are different ways to describe sound.

Students identify how the pitch and the loudness of an instrument can be altered by examining the sounds made by three instruments.

Students participate in a role-playing activity that demonstrates how whales use sound as an adaptation to their environment.

Home page for a hypertext physics course on auditorium acoustics and acoustical design.

Homepage for a hypertext about the different families of musical instruments. From this page, users can retrieve information on a the acoustics of a variety of specific instruments: stringed instruments, woodwind instruments, brass...

A physics tutorial on designing an auditorium and solving the problem of sound reflection. Illustrated.

This hypertext physics course tutorial on nonfocusing surfaces relates various design principles to good auditorium design. Illustrated.

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.

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.

[Free Registration/Login may be required to access all resource tools.] Explores what deafness is, how loud sounds cause hearing loss, and how to prevent hearing loss using hearing protectors.

Great animations showing how sound is produced.
