1 When the bones of the middle ear do not vibrate and become stiff, it can give rise to a hissing and vibrating sound in the ears. 2  Rupture of ear drum either due to trauma or due to loud sound can cause vibration in the ear during the initial stage. 3  Infection in the ear, cold and sinusitis can also cause vibration.
Through resonance, a comparatively weak vibration in one object can cause a strong vibration in another. By analogy, the term resonance is also used to describe the phenomenon by which an oscillating electric current is strengthened by an electric signal of a specific frequency.An example of resonance is provided by a motor that causes vibration in a piece of furniture in another part of the same house.These vibrations occur because the furniture has a natural frequency equal to the frequency of the vibrations set up by the motor.The furniture is said to be in resonance with the motor.echanical resonance can produce vibrations strong enough to destroy the object in which they occur. For example, soldiers marching over a bridge can set up extreme vibrations at the bridge's natural frequency and shake it apart.
