Man/Machine Interface in Material Handling
For example, some solutions use better material and designs to more firmly hold axial rollers in conveyor frames to dampen chattering. Other solutions involve adding noise-absorbing material within the machine construction. 3M offers a product that turns vibration into heat, which can then be dissipated, removing a lot of noise from a system.

Velocity: Velocity is related to the destructive force of vibration, making it the most important parameter. It places equal importance on both high and low frequencies. Usually, the RMS value of velocity (measured in the range of 10 to 10,000 Hz) shows the best sign of vibration severity. RMS is calculated by multiplying peak amplitude by 0.707.
