fun·da·men·tal fre·quen·cy

the principal component of a sound, which has the greatest wavelength, hence the lowest tone in a sound; sounds are composed of a fundamental tone and overtones or higher tones. See: harmony, noise.

(F0) (fŭn'dă-men'tăl frē'kwĕn-sē)
1. acoustics The basic frequency of a vibrating object or sound as opposed to its harmonics, or the principal component of a complex sound wave.
2. The frequency of vocal fold vibration at the glottis, unaffected by resonance.
