Industrial Noise and Vibration Control. Industrial plant personnel frequently contact Kinetics Noise Control for their recommendations on products to lower noise levels within their facilities. Kinetics' engineers have successfully reduced noise levels by as much as 30 decibels by the application of products such as: Curtains. Barriers. Baffles.

VIBRATION EMISSION MEASUREMENT METHODS FOR

The grinding test shows a larger spread between test runs, operators, and laboratories and over time. The unbalance disc test gives vibration values corresponding to the upper quartile of the real grinding test for grinders without autobalancing units. This is one requirement in the revised vibration measurement standard.
