According to the existing research, the natural frequency of a human-standing body is about 7.5 Hz , and the frequency of a sitting posture in the cab is generally 4–6 Hz. The natural frequency of the main body parts is shown in Table 1.
Read moreWhat is natural frequency and why is it important?
When an object vibrates at a frequency equivalent to its natural frequency, the vibration of the amplitude increases significantly which could lead to irreparable damage , therefore, it is important to know the natural frequency.
Read moreWhat is natural frequency example?
Another simple example of natural frequency is a tuning fork , which is designed to vibrate at a particular natural frequency. For example, a tuning fork for the musical note “A” vibrates at a frequency of 440 Hz.
Read moreWhat happens at the natural frequency?
Natural frequency is the rate at which an object vibrates when it is disturbed . Simple harmonic oscillators can be used to model the natural frequency of an object. Natural frequencies are different from forced frequencies, which occur by applying force to an object at a specific rate.
Read moreWhat is natural frequency formula?
When calculating the natural frequency, we use the following formula: f = ω ÷ 2π Here, the ω is the angular frequency of the oscillation that we measure in radians or seconds.17 Mar 2022

From the dawn of life on Earth, the planet has had what’s known as “natural frequency.” The Earth’s natural frequency is called the Schumann Resonance, which pulsates at a rate of 7.83 hertz .
