Noise and Vibration Control Example
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 32 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
Some more noise and vibration control examples are shown on the

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
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.
