Document Summary

Fundamental frequency: the rate at which the vocal folds vibrate. Know the average fundamental frequencies for males, females, and children. The fundamental frequency can remain the same for a series of vowel sounds produced by the same speaker. Speakers can alter amplitude and fundamental frequency independently, so that an increase in one can, but need not, be accompanied by an increase in the other. Acoustic energy is not only present simply at the fundamental frequency. Acoustic energy is present at the fundamental frequency & at whole number multiples of the fundamental frequency (harmonics) An adult male with a fundamental frequency of 100hz will have energy at: All the while, amplitude is decreasing as the number of harmonics increases. For a woman with a fundamental frequency of 200hz, the 2nd harmonic would be: Remember, the fundamental frequency is the 1st harmonic! If we know the fundamental frequency, we know all the harmonics.
