What is another name for resonance frequency?

This would be the harmonic with the longest wavelength and the lowest frequency. The lowest frequency produced by any particular instrument is known as the fundamental frequency . The fundamental frequency is also called the first harmonic of the instrument.

High-frequency resonance causes instability at the natural frequency of the mechanical system, typically between 500 and 1,200 Hz. Low-frequency resonance causes oscillations at the first phase crossover, typically 200 to 400 Hz .

Frequencies at which the response amplitude is a relative maximum are also known as resonant frequencies or resonance frequencies of the system .
