Industrial Noise Attenuation – Fans & Machines

Our company specialises in industrial noise attenuation for all types of fan and machine in industry and within other commercial companies. We offer solutions that use advanced technology and engineering techniques to achieve a high sound reduction. This type of solution is not widely available. The major benefit is much lower cost than other types of solution. Many companies have saved thousands of pounds by selecting our noise attenuation solutions instead of other noise solutions.

Another major benefit is that our specialist noise attenuation solutions often provide a much higher noise reduction than other types of solution. For noise nuisance affecting local residents, our solutions have often solved noise problems after other solutions failed to provide enough noise reduction to stop complaints. Where one solution is tried and doesn’t achieve sufficient noise reduction, this increases the time and money spent on the project. So our solutions can solve noise attenuation problems quicker and at lower cost. Fans are a common cause of noise nuisance, so most of our nuisance work is on industrial fans of all types – axial, centrifugal, extract, supply, HVAC, blowers, dust filters, etc.

Another advantage of our solutions is that they avoid access restrictions for operators, thereby maintaining productivity. Sometimes they improve machine performance as well as attenuating the noise. Our solutions can be applied to most types of industrial machine. There are many noise attenuation examples for numerous different types of machine, factory and industry on industrial noise control examples.

The following is an example of a solution that uses advanced technology to provide very high fan noise attenuation.

Fan Noise Attenuation Example

A low frequency hum from a scrap extract fan was causing noise nuisance to residents living close to a factory. A large noise reduction was needed because the fan operated all night. Silencers were considered initially. However, the sound reduction provided by silencers is very small at low frequencies, and would have been insufficient in this case. A higher noise reduction could have been achieved using a more complex type of silencer, but this would have imposed a large pressure drop on the fan. This would have reduced the performance of the fan and the scrap extract rate. This was unacceptable.

Our solution for the scrap extract fan used advanced technology to produce a very large fan hum attenuation. Tests showed that it produced a very large noise reduction of 19 decibels (dB) – i.e. the fan hum was reduced by 19 decibels. This very large fall in the noise level meant that the fan hum was completely inaudible at the nearest houses afterwards. Previously the fan hum had been very noticeable here and had been causing considerable annoyance.

In addition to the very high fan sound attenuation, our solution maintained the scrap extract rate and there was no loss of fan performance. So, compared with a silencer, this solution combined very large sound reduction with substantial performance benefits.
