Some of these are Word and Excel docs I created, others are links to online Acrobat pdf's, gifs, jpegs, or html, etc websites. If you have any difficulties with the Excel or Word docs, please let me know. (IE opens them OK on my WinXP system, which doesn't have Excel on it)
Please let me know if any links don't work or have died. I run a linkchecker regularly, but some websites seem to get 'redecorated' constantly...

Manuals, data sheets for other SCC Sound Gear:
Formulas :
Frequency = 1 / the period of one cycle (Ex: 1 / 10 milliseconds = 100Hz)
FYI: Period of one cycle = 1 / Frequency (Ex: 1 / 100Hz = 0.010 seconds = 10 millisec's)
Wavelength (lambda, Λ) = Velocity / Frequency
Wavelength = The distance it takes for a wave to complete one cycle, in feet or meters.
Velocity = Speed of Sound (~1130 feet per second, ~1ft/msec, ~344 meters per second)
Frequency = Cycles per second (Hz)
