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.

fun·da·men·tal fre·quen·cy

(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.

It is observed that in contrast to the implementation of nonlocality which causes to reduce the stiffness of SLGS, by taking into account of elastic foundation, the natural frequency increases for all values of nonlocal parameter and this effect is more significant for higher aspect ratios relevant to all mode numbers which is again in contrast to the nonlocality effect that is more considerable in the lower aspect ratios.
