            Noise Control

            Noise Control

            Only once it is quiet do you realise how much noise there is on any given day. And how unpleasant this can be. Ventilation systems, machinery and vehicles create continuous noise. Excessive exposure to this can cause stress, buzzing in your ears, high blood pressure, as well as heart problems. Good reason why government enacts laws and regulations that provide for a better sound climate. But even when public health is not at risk, silence is a precious commodity. Merford helps you control any undesirable noise in various ways. Whether you need to comply with the latest noise legislation or want to compete with the quietest machine on the market, we can help you.  

            Almost every source of sounds can be confined in the amount of noise it's producing
            Merford has lots of possibilities to accomodate almost every room with good acoustics

            Our expertise
            Controlling decibels is a precise task. To guarantee optimal noise reduction, we first conduct meticulous tests and measurements using calibrated measuring equipment. We do this on-site or in our own test room: the Silence Factory. Using acoustic cameras (sound imaging) we can easily localise the source and strength of the noise. Following a meticulous analysis, our experts design a solution for you in 3D. Naturally, our solution provides due consideration to your wishes and the legal requirements that apply to your situation. We have all the required thermal insulation, fire safety, ventilation, cooling, lighting and explosion safety (ATEX) expertise in-house for this purpose.

            Turnkey solutions
            It may be that the solution to your noise issues is best provided in the form of a total product: a turnkey solution. In that case Merford ensures that the source of the noise is completely insulated through means of a housing or a different kind of structure. In actual practice such sources often consist of machinery, equipment or installations that vary significantly in terms of size and level of noise. Merford delivers these solutions ready-made, without any need for concern on your part. Our project managers guide the entire process, from sound measurement to final assembly.

            Acoustic materials
            Sometimes a noise problem requires an integrated solution. For example, when you want to dampen a motor’s vibrations or reduce the sound produced by a CH boiler. In such instances we incorporate acoustic materials into your product. We will meet with your Research & Development department to develop the most effective design and you fully benefit from our knowledge and experience. Once the product is ready for market, we supply just-in-time so that your production line never comes to a standstill. Merford also uses acoustic materials or components for spatial acoustics. For example, if you want to absorb the reverberations in a meeting room, acoustic panels may be a good solution. If we do not have a readily available solution in our webshop, we can create a custom-made product.

              In 2013, the American company, Praxair, announced the construction of a second air separation plant in the port of Antwerp. The plant is scheduled to be delivered in mid-2016. Merford has equipped a large compressor building in this plant with measures designed to make the entire building silent to its surroundings.

              In 2013, Merford was awarded a contract for the design and construction of four sound-insulating enclosures for Siemens Energy Oil & Gas for the Norwegian production platform Edvard Grieg. The enclosures will be installed around Siemens compressor trains on two decks of the platform’s Process Module. The compressors will be used to transport gas from the production platform to the Scottish coast and to the Sleipner A platform, as well as for re-injecting gas into the field. To protect operators in the immediate environment of the compressor skids, it was decided to equip the installations with sound-insulating enclosures.

              On behalf of Royal Smit Transformers, Merford Noise Control has developed a set of sound-insulating enclosures for the large power transformers and shunt reactors of an offshore wind farm. The enclosures have been equipped with sound-insulated ventilation systems. This combination limits the emission of noise to a sound power level of 70 dB(A).

              Westland Infra

              A transformer station owned by Westland Infra Netbeheer in the Dutch town of Poeldijk has recently been fitted with an Active Noise Reduction (ANR) system. This makes use of a technology which is also known as anti-noise. There were plans to build new houses close to the transformer station so the transformer station had to meet certain noise requirements. Merford was asked to find a way to reduce the noise pollution levels to a maximum of 40 dB, at a distance of 21 metres on the side of the station where the houses were to be built. An ANR solution was developed to be installed in the transformer station so the sound emissions were reduced to the required levels.

              Suiker Unie

              Suiker Unie develops, produces and sells sugar and specialty sugar products. Its factories are among the most modern in the world. In 2017, the European sugar market regulation expires, which means the production capacity can be increased by 25 per cent. In response to this production expansion, the Suiker Unie factory in Dinteloord will gradually be extended. To reduce the factory’s noise pollution to a minimum for the environment, action was needed. Merford supplied five acoustic enclosures for the transport screws and pulp presses.
