Vibrating objects in the unit of time the number of vibrations, commonly used symbols f, the frequency of the unit for times / second, also known as Hertz. The frequency of vibration indicates the speed of vibration of the object, in the vibration of the disease-causing effect, the frequency plays an important role. Large amplitude low-frequency (20Hz or less) vibration, mainly in the vestibular organs, and make the viscera displacement; small amplitude, high-frequency vibration, mainly on the central nervous system and a variety of tissues within the role of nerve endings.

Definition
The period T is the time in seconds [s] that it takes for an object to complete a vibration process. For example, a single pendulum, its period is the time it takes for the weight to move from the left to the right and then from the right back to its starting point on the left.
Frequency and period are the inverse of each other, f=1 / T.
