Undesired commotion and vibrations are since ever a noteworthy issue in numerous human exercises and domains. Airplanes, space trusses and satellites, cars, machine tools and large bridges, all can be disturbed in their normal functions by vibrations and noise. So to reduce vibrations there are various damping techniques which can be mainly categorized as active, Semi-active and passive damping. Among these active damping requires arrangement along with sensors which finally increases cost. On other hand passive damping can be easily combined with vibrating structure. Passive damping has various techniques such as viscous damping, viscoelastic damping etc. but each of it have certain limitations which may be environmental conditions or temperature varieties or connection with vibrating structure without changing its qualities (such as its stiffness, weight etc.).So recently developed particle impact damping (PID) is proving to be one of the techniques which overcome most of the limitations of above said. This paper focuses or discusses on the methods to reduce vibrations by using various damping techniques. Paper is a review of various literatures available on different types of vibration damping.

Keywords: Vibration Damping, Viscous Damping, Particle Impact Damping, Vibration Isolators.
