Noise and Vibration Control for Industrial Compressors at Training Centre

Industrial noise and vibration control is the centre of our work. Many customers have saved thousands of pounds by selecting our unusual range of noise and vibration control solutions instead of using common types of solution. Honed by over 35 years' experience, our noise and vibration control solutions form a centre of excellence. They use advanced technology and engineering techniques to provide high noise and vibration reduction at low cost. Here is one of our case studies of vibration and noise control that centre on solving a noise nuisance problem caused by vibration.

Several compressors located in the centre of a plant room were causing noise disturbance in a nearby training room. Our tests showed that most of the noise was structure-borne, caused by vibration transmission from the compressors through the building structure to the training centre.

So, we designed a vibration isolation scheme to reduce the structure-borne noise. This involved selecting a suitable type of anti-vibration mount for the compressors and for various lengths of pipe. The type of anti-vibration mount used was chosen specifically to provide a high reduction in vibration at the main noise frequencies causing the annoyance in the training room.

The solution provided both noise and vibration control. So, it reduced vibration within the floor of the compressor house as well as the noise transmitted to the training centre. Prior to installation of the noise and vibration control treatment, vibration levels in the compressor house floor were relatively high, causing discomfort to workers.

It is common for a noise nuisance problem within a building to be caused by vibration, and to require a noise and vibration control solution of this type. However, this is not always the case. Sometimes, the nuisance is caused by airborne noise transmission. In this case, vibration control measures such as anti-vibration mounts will not reduce the noise nuisance. It is very important to carry out diagnostic noise and vibration tests beforehand, to determine whether the cause is vibration or airborne noise. Otherwise considerable time and money can be wasted on treatment that fails to resolve the noise nuisance problem.

It is also common to find that the anti-vibration mounts that have been fitted are inadequate. Normally, an industrial anti vibration mount is selected using theoretical data only, whereas the vibration reduction achieved is very dependent on the vibration response of the structure that the anti-vibration mount is attached to. Resonances can mean that, in some cases instead of reducing it, the anti-vibration mounts actually increase the vibration level !

By carrying out vibration measurements on both the support structure and the vibration source (industrial machine), together with narrow band frequency analysis, we can determine the optimum noise and vibration control solution, that achieves the highest possible vibration reduction at the frequencies causing the discomfort or noise nuisance.
