Vibration
Control
Noise and vibration are closely
linked. We provide noise and
vibration consultancy and failure analysis for a variety of machines.
We specialise in industrial projects and gas
turbines. Our expertise extends to other forms of turbo machinery,
including marine propulsion systems, wind turbines, propellers and
fans.
Site surveys of noise and
vibration can be used to establish the cause of a problem.
Trouble-shooting is offered, to identify and rectify industrial
noise and vibration problems.

Finite element
analysis may be used in conjunction with site
measurements, to get a better understanding of a vibration
problem. Optimisation
techniques can be
used to improve the
design.
Noise
and Acoustics Consultancy
Coupland Bell provides
acoustics and dynamics consultancy for a variety of commercial and
industrial
projects. We can offer a complete design service, to ensure contract
and
planning
limits are met.
At the design stage, we use CadnaA software to predict the propagation
of noise from industrial sources around
|
|
 |
|
buildings and other
obstacles. This is a very powerful tool which can be used to
minimise the cost of acoustic materials.
Our
services include datum surveys to identify and quantify noise
levels. Further surveys during a construction project can be
helpful, to demonstrate compliance with planning limits, or to measure
the improvement from design changes.
We have unique expertise in
measuring noise in hot ducts, including engine exhausts.
We draw on our marine experience
to help our clients meet
the noise requirements of the European Recreation Craft Directive
(RCD). |
