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 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.

Home page for a hypertext course on physics. Accesses a range of topics from hearing to sound measurement to sound propoation to musical instruments.

[Free Registration/Login Required] This flipchart introduces fifth grade students to what sound waves do when they encounter an object. Topics covered include diffraction, reflection, absorption, and the Doppler Effect. An assessment is...

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.

Informational site on sound provides waveform illustrations of sound pitch. Provides additional information on ultrasounds, waves, reflection and much more.

Here are instructions for a simple demonstration showing how sound waves are passed from one molecule to another. Using only marbles, this experiment "mimics the way a sounds wave is produced."

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...

An exceptional entry for interference of sound and its causes. Well illustrated and good explanations; part of a large hyper-textbook on various physics concepts.

This lesson will describe how the doppler effect is created by moving sound waves. It is 2 of 4 in the series titled "Doppler Effect."

This lesson will describe how the doppler effect is created by moving sound waves. It is 3 of 4 in the series titled "Doppler Effect."

This lesson will discuss the differences in constructive and destructive wave interference. It is 2 of 2 in the series titled "Wave Interference."

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

This hypertext physics course surveys sound resonance in musical instruments. Illustrated.

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.

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.

Power, loudness, and decibel levels of sound waves are described and explained. The relative power output of various musical instruments is given.

A photo taken from the inside of an anechoic chamber. The effect of rebounding sound waves is kept to a minimum in such an anechoic chamber thanks to the large surface area that absorbs most of the noise.

Reginald Fessenden (1866-1932) was an inventor who worked for a time in Thomas Edison's workshop. His most notable inventions made possible the transmission of audio sounds via radio waves, and included many other radio-related...
