Practical Industrial Noise Reduction Solutions

Noise at Work

We are a specialist industrial noise reduction company, and noise control in industry represents the majority of our work. We have provided practical noise control solutions for a very wide variety of industrial machinery, equipment, factories and companies throughout the UK. Below are just a few examples of the industrial noise reduction solutions we have provided for some of the most common types of industrial machine.

We often help our customers save thousands of pounds on the cost of noise control by providing a much wider range of industrial noise reduction solutions than other companies, and by using advanced soundproofing technology and noise cancelling techniques. There are more examples on other pages of this web site, many illustrating the large savings in noise reduction costs that our company often achieves for manufacturing industry. For details, click on our Industrial Noise Reduction, Industrial Noise Control - Noise at Work and Industrial Noise Control - Noise Nuisance pages.

In all of the examples below, we used an engineering solution or advanced noise cancelling or soundproofing technology to reduce the noise at source at low cost. We have provided noise reducing solutions for many other types of machine, company, industry and equipment not listed below. Contact us for details of our other types of industrial noise reduction solution.

Examples of Noise Reduction Solution in Industry

Air Conveyors. An industrial noise reduction company quoted £130,000 to reduce noise from air conveyors (airveyors) by installing noise control enclosures. The customer chose our company instead. Our engineering solution was applied, reducing the noise by 6 dBA to below the 85 dBA target. Our solution cost only £2500, saving the company £127,500.

Air Knife. A purpose designed silencer and air flow modifications were used to reduce noise from an air knife by 11 dBA. The noise at the nearest worker fell from 93 dBA to 82 dBA.

Air Jets. Compressed air jets are commonly used in industry to dry, cool, or eject components. Using minor engineering modifications, we have achieved noise reductions of 7 - 15 dBA on numerous air jets while reducing compressed air usage and energy consumption at the same time.

Belt noise. Technique used: engineer noise out at source. Result: 10 - 12 dBA noise reductions on a range of different machinery drives where belt noise was the problem.

Blower. Noise reductions of 13 - 15 dBA achieved on a variety of different industrial blowers.

Blow mould machine. The diagnostic tests carried out by our engineer showed that most of the noise was generated by compressed air jet nozzles used for cooling. Treating these cooling air jet nozzles gave a noise reduction of 7 - 9 dBA on a range of different blow mould machines. Air jets are a very common cause of high noise levels in UK industry, and we can reduce noise from these at very low cost.

Cardboard slitter & cutter. Guard modifications provided 9 dBA noise reductions on a slitter and cutter machine used in the cardboard industry.

Compressed air. Numerous compressed air noise problems have been solved successfully. For example, treating compressed air jet nozzles on a can drier in the drinks industry provided a 15 dBA noise reduction at very low cost.

Compressor. Noise reductions of 6 - 10 dBA achieved on various types of compressor by purpose-designing a silencer. Our silencers are all designed to have a very low resistance to air flow. In contrast, most commercial high performance types of silencer have high resistance, which can impair fan performance and cause overheating.

Cyclone. Advanced noise cancelling technology has been applied to several types of cyclone, reducing noise by 21 dBA. This very large noise reduction was achieved at very low cost using minor engineering modifications fitted inside each cyclone.

Drier. 10 - 11 dBA noise reduction achieved on several different driers by purpose-designing a high performance silencer. Each silencer was designed to have low resistance to air flow, and so cause no significant loss of fan or drier performance.

Drink industry filling machine impacts. Practical engineering modifications were fitted to a filling machine in the drink industry, reducing the impact noise generated by the filler by 7 - 11 dBA at low cost.

Electric motor. Noise reductions of about 10 dBA achieved on a many different types of electric motor by purpose-designing a silencer.

Fan noise. Our company has provided solutions for most types of industrial fan noise problem. We have successfully treated numerous different types of extraction fan, achieving noise reductions of up to 17 dBA. We use various solutions to reduce the noise, including engineering modifications and advanced soundproofing technology. Where there is a fan "hum" or "whine", by using specialist noise cancellation technology, we can often provide higher noise reductions than are possible with common types of solution. We have achieved noise reductions of up to 22 - 25 dB for fan hums and whines. See the noise nuisance pages on this web site for examples of extraction fan noise reduction solutions.

Food chopper. A purpose designed silencer was fitted to the material infeed and outfeed ports, reducing noise on a food chopper machine by 22 dBA. Our company offers various types of practical noise control solution that are suitable for the stringent hygiene requirements within the food, drink and pharmaceutical industries. Much of our noise reduction work is for food companies. We also carry out a substantial amount of work to reduce noise for drink and pharmaceutical companies.

Grader. The noise from several vibratory graders was reduced by 10 - 11 dBA by applying low cost engineering solutions to the production machines.

Hydraulic noise. Minor engineering modifications were designed for the hydraulic drive on a mixer, reducing the noise by 7 dBA at very low cost. This practical noise control solution can be applied to most types of hydraulic noise problem and a wide range of hydraulic machinery & equipment.

Hydraulic pump. Low cost engineering modifications were used to reduce noise by 15 - 17 dBA on a hydraulic pump that drives a large industrial mixer. This solution was very successful, reducing noise from 97 dBA to 80 - 82 dBA at low cost.

Impact noise problems. Noise reductions of 7 - 11 dBA have been achieved on a wide variety of machinery, equipment and types of chute, using a highly durable and practical noise control solution to reduce impact noise. Because it incorporates a steel impact surface, our solution avoids the problems of the soft rubber like materials that are commonly used to reduce impact noise. Soft materials can quickly wear completely away, whereupon the high impact noise level returns. As they wear, these soft rubber-like materials can also contaminate the product. This can be a major problem on chute and other types of impact surface in a hygienic industry such as the food, drinks and pharmaceutical industries. Impact noise is very common in industrial companies. Consequently, we have considerable experience of reducing impact noise in many different industrial applications.

Lathe. 7 - 8 dBA noise reductions achieved on various types of multi-spindle automatic lathe.

Mixer. On various types of mixer in the food, power generation and other types of industry, we have achieved a noise reduction of between 6 and 17 dBA.

Paint booth supply and extract fans. Slightly adjusting the air flow on each supply and extract fan made a large difference to the noise inside a paint spray booth, reducing it by 3 - 6 dBA without impairing extraction performance. This noise reduction was achieved at very low cost.

Pipe noise. A supplier and installer of gas compressors and pipework was spending large sums of money on acoustic lagging to reduce the noise radiated by the pipes used to carry gas around the plant. We provided an alternative solution that achieved a much higher noise reduction at considerably lower cost. This avoided the need to fit acoustic pipe lagging. The savings amounted to about £5000 per site on average.

Pipes. Low cost engineering modifications were applied to pipes containing hydraulic fluid, reducing pipe radiated noise by 15 - 17 dBA.

Plastic extruder. A high performance engineering vibration damping treatment was used to reduce noise by 5 dBA on a plastic extruder. Our engineer carried out the work directly for the manufacturer, and they applied the solution to all their machines of that type (achieving similar noise reductions).

Press. Engineering solutions have produced noise reductions of between 7 and 11 dBA on many different presses at low cost. Power press noise is a common industrial problem. The common solution is to fit an acoustic enclosure around each press. This is a very costly solution. It also restricts access to the press, so can impair productivity. Engineering types of solution avoid this, and they cost considerably less. The cost savings are enormous, particularly where there are a substantial number of presses.

Pumps. See hydraulic pumps, above, and vacuum pumps, below.

Stitching machine. 5 - 7 dBA noise reduction achieved on numerous stitching machines at very low cost, reducing workers' noise to below 80 dBA.

Trim extract fan. 8 dBA noise reduction provided on a side trim extract fan in the cardboard industry at very low cost, reducing noise at the nearest worker to 81 dBA.

Tablet packaging lines. In the pharmaceutical industry, we reduced the noise by up to 16 dBA on tablet packing lines using engineering solutions that cost little to install. Similar noise reduction modifications were applied to other parts of the production lines.

Vacuum pump. 7 - 8 dBA noise reductions achieved on many different types of vacuum pump.

Vibratory bowl feeder. Minor engineering modifications to the product feed guides were used to reduce noise on various types of vibrating bowl feeder by 12 dBA at very low cost.

Vibratory deburrer. Noise reduction of 7 dBA on vibrating deburrer machines, reducing nearest worker's noise to 83 dBA.

Vibratory conveyor, separator, weigher, feeder. Noise reductions of 10 - 11 dBA achieved on a variety of vibrating and deburring machinery & equipment including various types of separator, weigher, conveyor, vibrator and feeder for powder & other product.

Waste extract fan. 5 dBA noise reduction produced on various types of waste extract fan.

Wood planer & thicknesser. 8 -13 dBA noise reductions achieved on a variety of wood planer & thicknesser machines using minor, low cost engineering modifications and other practical noise control solutions.

Wood saw. 5 - 8 dBA noise reduction on many types of wood saw at very low cost using various types of practical noise control solution.

Industry & Machine Type

The current Control of Noise at Work regulations strongly emphasise that each UK company must implement noise control at source to reduce deafness risks, instead of relying on ear protectors. So, noise control is an essential element of any programme to comply with the regulation in all factory and industrial environments where the noise level is high.

Our company has solved many types of noise control problem for numerous manufacturing companies, across a very diverse and wide range of industrial sectors throughout the UK.

Advanced Noise Solutions Ltd

could help you save thousands of pounds on industrial noise reduction

Our company works throughout the UK.

We have a reputation for providing accurate, thorough and reliable assessments of workers noise exposure. Clients often compliment us on the high quality of our work noise risk assessments and compare them favourably with cheap noise surveys that they have had previously, many of which do not even attempt to assess workers noise exposure and fail to comply with the Noise at Work Regulations.
Because they involve minor engineering modifications, our advanced industrial noise control solutions do not restrict access for operating or maintaining machines. This contrasts with noise control enclosures and acoustic hoods, which can impede access to such an extent that production falls. Often workers leave doors and acoustic hoods open to improve access, with the result that the acoustic enclosure or hood achieves little or no noise reduction
our engineering noise control solution for some vibratory bowl feeders not only achieved a noise reduction of 12 dBA (reducing work place noise levels from 98 dBA to 86 dBA), but also eliminated the blockages that had been causing frequent machine stoppages. This increased output and enabled each operator to monitor a larger number of machines, so improving productivity. The noise control equipment normally used in such situations - acoustic enclosures, acoustic hoods, acoustic covers - would not have provided these benefits.
