## Document Summary

"ssss" sound is a higher frequency than "sssh" 1 complete cycle of vibration in 1 second = 1 hz. 2 complete cycles of vibration in 1 second = 2 hz octave = doubling frequency, every time we move up one octave we"re doubling (not adding), any 2 to 1 frequency ratio. = . 662 meters/cycle (about 2 feet) on exams we will not have to adjust the speed of sound for temperature, we will have one of two options. At 0 c = 331. 4 m/s at room temp = 344. 1 m/s spectrum: aka frequency line spectrum, amplitude spectrum frequency on x axis, amplitude on y axis. *no time component, thus it represents the frequency measurement at a particular time vertical lines (for waves we have oscillating lines) (cid:12254: amplitude (second property of sound) 0. 0002 dynes/cm^2 (
