Document Summary
Harmonics: addition of pure tones/sine waves of cert. freq"s; harm. sound if there is a cert. reg. relat. b/w these sounds/mult. freq"s of fundamental freq"s (or first harmonic) - e. g. 2nd freq. is. 2x as big as fund. freq. , 3rd freq. is 3x the fundamental/first harmonic. Missing-fundamental effect: lots of freq"s in spectrum but when sound heard what is perceived is freq. of first harmonic/fund. freq. When fund. freq. is not audible/has no power you still perceive it even though it"s not there. Even if more missing, you will still perceive it. = 10 b/c distance b/w neighbouring freq. "s is 10. First graph: fund. freq. , second: fund. freq. removed; third: 2nd harmonic removed; fourth: 3rd harmonic removed; fifth graph: 4th harmonic removed. First: peaks have the same distance as peaks in original harmonic sound; still seen in graphs removing subsequent harmonics (same peaks seen)
