When an object is subject to damping, the most resonant frequency is given by the formula f=SQRT(k/m - b2/4m2). This results in an objects resonant frequency getting progressively lower as damping increases.
How does damping affect resonance frequency?
The effect of damping on resonance graph: The amplitude of the resonance peak decreases and the peak occurs at a lower frequency. So damping lowers the natural frequency of an object and also decreases the magnitude of the amplitude of the wave.
How does damping ratio affect frequency?
Damping is the absorption of the energy of oscillations, by whatever means. Generally, this results in the decreased amplitude of the waves. The processes which result in damping also reduce the natural frequency of a system.
