THESE ARE LINKS TO THE CLARINET-OBOE SOUND FILES:
These are the computer generated sound files that I played in class of 300 Hz accompanied by all integer or only odd integer harmonics: all integer harmonics and odd integer harmonics. For comparison, here are the two solo sample clips from Peter and the Wolf played on real instruments: test 1 and test 2. (Testament to my computer incompetence, some browsers and settings will not open these files automatically; in any case, you should be able to download them. )
Send me an e-mail with the title of your choice and 50 to 100 words on why you chose it. A short book report will be due by Friday, 11/9 (-- details to follow).
The current SFL Reserve set-up limits how long you can have any book at a stretch. If only one student wants a particular book, I'll have them release it to you. If more than one student wants a particular book, we'll work something out...)
From "This Is Your Brain on Music" DUE Monday, 10/8: Intro and chapter 1; DUE Monday, 10/15: chapters 2, 3, and 4; DUE Monday, 10/22 chapters 5, 6, and 7; DUE Monday, 10/29 chapters 8 and 9 AND read the eight other students' essays on "Impact of Recorded Music" (see e-mail for link) and re-read your own.
Here is a list and description of some sound analysis freeware. Spectroid (linked here) is my latest addition to the list, a free app that gives a nice real-time spectrum of the sound coming in to your device.
There are zillions of "educational" sound-related pages on the Web, with demos, simulations, explanations, and derivations. Many of the ones I list explicitly are part of someone's much larger effort to present some science. So, if you use your browser to go back up their tree, you will likely come to a directory or a page with lots of related links.
Here are a few, in random order:
Visualizing molecule motion of sound in air -- a cartooney animation
whyyouhearwhatyouhear.com is a maintained and updated Web site that goes with the book of the same name (#18 on our SF Library reserve list). It's got great demos, resource links, and explanations.
At the University of New South Wales (Australia), they have a serious physics of music program with lots of stuff on-line. (Here is another portal to their site.)
An energetic science teacher worked up a course and put it into book form: The Physics of Music and Musical Instruments. Very readable and accessible and at an elementary level and only about 100 pages total, it might serve as a good reference for things mentioned in class.
A particle physics experimentalist has taught a sophisticated physics of music course at the University of Indiana. Its Web site from a couple of years ago (still posted [are there up-dates?]) has a lot of interesting stuff. Scroll down and click on "Teaching" and/or P105 - Basic Physics of Sound. (We should talk sometime about cochlear implants.)
A group at the University of Colorado produces wonderful interactive physics simulations. This is the one on waves on a string.
Hyperphysics, produced at Georgia State University, has a "Sound and Hearing" section with useful materials.
I can't figure out who Paul Falstad is, but he puts great physics applets on-line.
These days, Wolfram Enterprises is the home of much more than Mathematica. Three demonstrations on demonstrations.wolfram.com recently caught my eye: locating the hammer on a piano wire; string vibrations; and vibrations of simple systems. These demos are best with a free downloadable player. (Also note that Caltech has a Mathematica site license -- as well as lots of other stuff you can get for free from IMSS.)
