What are the physics of sound?

For more information please visit Industrial Hearing Services


The Soundry - An exciting, interative, and educatinoal website about sound. Covering everything from the most basic concepts of what sound actually is to the specifics of how humans perceive it. The Soundry aims to promote enthusiasm and knowledge of sound. We hope you have fun exploring our site and come away with new understanding and insights about sound: library.thinkquest.org
Fourier Synthesis - Hands-on synthesis of complex tones. Add lots of pure tones together and hear the complex tone that emerges: phy.ntnu.edu.tw/.../sound.html
HyperPhysics - Extensive links for sound measurement and physics of sound. Select "Sound and Hearing" link: hyperphysics.phy-astr.gsu.edu
Kettering University - Some really well done demonstrations of the physics of sound developed by Dan Russell: kettering.edu For example, the following link shows animations of transverse and longitudinal waves: kettering.edu
FrontierNet - This site involves a makeshift piano that you can play songs on and view what kind of different waveforms playing various notes can make: frontiernet.net
Glenbrook South High School - An explanation of a longitudinal wave, a good physics resource for high school students: glenbrook.k12.il.us
Find Sounds on the web - You can find all sorts of sounds and then analyze their physical characteristics with a program like CoolEdit: findsounds.com
Acoustics and You - A website on possible chareers that include acoustics: asa.aip.org
The Physics Classroom - Includes information on the nature of sound, including animations of longitudinal sound waves as well as teh physics of musical sounds: physicsclassroom.com
