● Noise measurement in the R & D test center
● Noise measurement locally at the customer
● Airborne noise measurement on individual hydraulic components and complete units
● Structure-borne noise measurement to prove the efficiency of ROKEN damping elements
● Optimization of noise levels of systems or hydraulic units
In its research and development test center, ROKEN has provided for a sound measurement room allowing for low reflective test conditions. Comparative measurements are performed on an actual hydraulic power pack in order to test and optimize the efficiency of ROKEN damping elements. Apart from the stationary measurement in the laboratory, the efficiency of the ROKEN damping measurements taken can be proven locally.
Effect:
The effect of the ROKEN damping elements reflects the structure-borne noise vibration by means of the vulcanized, non-prestressed rubber layer in the acoustic frequency range from about 200Hz. The reduction of structure-borne noise vibrations causes a reduced radiation of the airborne noise produced by the power pack.
