Industrial Noise Abatement

Industrial Noise Nuisance Solutions

We use advanced technology and specialist engineering techniques to achieve high noise reduction at considerably lower cost than common types of noise abatement solution. As a result, we often help our customers save thousands of pounds on the cost of suppressing industrial noise nuisance.

We have solved many industrial noise nuisance problems after other solutions have failed. This is because our specialist noise abatement solutions provide much higher noise reduction than other types of noise control solution. Other solutions, such as a sound barrier, noise enclosure, acoustic screen, fan silencer, etc. reduce the noise to some extent but often do not fully resolve the problem, so complaints continue. Our solutions provide such a high sound reduction that they usually make the annoying sound inaudible at the nearest houses to the factory, fan or other equipment causing the noise nuisance.

Our specialist noise abatement company has over 35 years' experience of helping industrial companies to solve noise pollution problems. Our solutions have been applied successfully to many types of fan, machine and equipment in all types of factory. We have also helped non-industrial commercial companies that have noisy fans, chillers and air conditioning systems, to solve their noise nuisance problems.

Noise Abatement Services and Procedure

Our first step in any noise reduction project is to identify the precise cause of the nuisance. Our company has considerable expertise and experience in identifying the main noise sources. Using this and highly sophisticated measurement and frequency analysis equipment, we can pinpoint the causes of a noise nuisance problem very accurately and precisely, even down to an individual fan, gear or bearing. This ensures that the money spent on noise abatement services is targeted where it has most effect and avoids wasted expenditure.

Noise Abatement Solutions

Solutions that use advanced noise reduction technology or engineering techniques to reduce the sound at source provide many benefits over more common types of noise attenuation solution. The major benefits include: large cost savings, higher noise reductions, avoiding loss of machine performance plus saving time and money spent on maintenance. The benefits are so large that we use this type of solution to control noise nuisance whenever possible, and only use common noise abatement solutions, such as a sound barrier, acoustic screen, or acoustic enclosure, as a last resort.

Some examples of the benefits of using our advanced technology or engineering techniques to reduce the noise at source are given below:-

1) Large cost savings

Example: control of noise nuisance from two large extract fans

Usual method: acoustic enclosure and silencer for each fan: Cost: £10,000
Our specialist fan noise abatement solution: Cost: £4,500. Saving: £5,500

Example: low frequency boiler drone (53 Hz) noise problem

The usual noise attenuation method for a boiler is a large industrial silencer. To reduce the drone sound by 20 dB, a silencer manufacturer quoted £10,000 - £14,000 depending on the allowable pressure drop. Our engineering solution reduced the boiler drone by 22 dB with no pressure drop. Cost: £2000. Saving: £8,000 - £12,000.

2) Higher noise reduction than common solutions

Example: reduce noise nuisance from food industry fan

A low frequency fan noise drone was causing nuisance to local residents. Because the performance of silencers is very poor at low frequencies, a standard silencer or attenuator would have reduced the drone by only 3 dB. This is such a small sound reduction that residents would not have noticed any difference. Using advanced technology, our fan noise abatement solution reduced the noise drone by 19 dB.

This is 16 dB higher noise reduction than the silencer could have provided. Our solution achieved such a large noise reduction that it completely eliminated the drone sound, making it inaudible at the nearest house. It cost less than fitting a silencer to each fan and can be cleaned using high pressure water, which was a food industry hygiene requirement. A silencer could not have been cleaned in this way.

Example: drier, furnace, flare, burner & boiler noise nuisance control

Low frequency combustion noise, i.e. hums / drones from various types of boiler, dryer, furnace, etc. are a common cause of noise nuisance. The drone frequency is usually so low that normal sound suppression equipment like an industrial silencer or attenuator provides little noise reduction (unless a very large, complex silencer is used, which is extremely expensive). In contrast, our advanced technology solutions provide large noise reductions at low cost. Here are a few examples of the very large noise reductions achieved for several low frequency drones:-

3) Higher production performance

Example: industrial fan noise abatement solution

Where high noise reduction is required for an industrial fan, the type of silencer normally used imposes high resistance to airflow because this is the only way that a silencer can achieve the large noise reduction needed. This high resistance can impair fan performance considerably, which can result in the airflow / extraction performance being inadequate.

The solutions we normally use to reduce industrial fan noise have very low flow resistance so they do not significantly reduce fan performance or increase energy consumption. This means that our solutions can provide large performance benefits over common noise abatement solutions such as a silencer.

4) Save time and money spent on maintenance

Example: industrial fan noise abatement in a factory

The normal sound attenuation method to control noise nuisance from a fan is an industrial silencer, which can require periodic cleaning and replacement, particularly where the air is dusty. This means that regular maintenance is required, costing time and money.

Advanced technology fan noise control solutions involve engineering modifications that last the life of the fan without maintenance. So, an advanced technology solution solves the noise problem permanently, preventing complaints resurfacing later as can occur with a silencer when it becomes clogged by dust. Also, there are no maintenance costs, or machine down time for maintenance.

As a result of these large benefits, our engineering and advanced technology solutions and noise abatement services have proved a very successful way to reduce noise nuisance. Our industrial noise control services have become so popular that a substantial amount of our work involves helping industry to resolve nuisance complaints and comply with noise abatement notices.
