Soundproofing for Manufacturing Facilities

What are the challenges for sound insulation in industrial buildings and facilities?

Sound insulation in industrial buildings and factories has two main goals: to reduce noise for employees in the facility and soundproofing for the outside.
This should prevent noise from becoming a problem for neighbors and residents.

Noise in Manufacturing Processes

Soundproofing for large manufacturing factories and facilities is a challenging task mostly because there are several noisy types of equipment that usually run at the same time within the complex:

  • Vibrating panels
  • Fans
  • Air-flow
  • Impact processes
  • Engines
  • Processors
  • Other manufacturing equipment

The large number and variety of equipment within the plant force plant operators to face unique challenges when trying to find a comprehensive solution for noise mitigation.

This combination of different noise sources can contribute to the overall noise levels. But it is not only the numerous sound sources in the facility that influence the selection of the right sound insulation elements but also the structural features of the environment in which the source takes place. For example, Sound-reflecting surfaces, e.g. concrete, stone, or metal, along with high ceilings and wide rooms, can cause strong reverberation and long reverberation times.

Sound Insulation for Manufacturing

How the noise is controlled is dependent on the source. For instance, external noise caused by HVAC units or process pumps is assessed and treated differently to internal noise sources such as plant machinery.

There are several possibilities for soundproofing in manufacturing facilities. Noise can be dampened, for example, by using soundproofing solutions on individual machines and devices such as acoustic enclosures or different types of silencers.

Because of the variety of contributing noise sources in this kind of facility, there is no one-size-fits-all solution. Due to the complexity of the acoustical challenges this sector face, a tailored solution is required to ensure the deployment of effective noise control systems.

Following an initial consultation path with a leading industrial and environmental noise control manufacturer, is the quickest and most effective way to solve complex noise mitigation challenges.

Stopson Italiana has worked internationally with plant processing engineers and their consulting teams to provide accurate and cost-efficient, site-wide noise assessments and mitigation solutions of industrial sectors such as petrochemical complexes both large and small.

Noise reduction in Petrochemical plants

Tackling Noise Containment in Petrochemical facilities: Concept, Principle and Challenges

Oil and gas infrastructure, from extraction, to refining and processing, to pipeline transmission and distribution make use of some of the largest, most powerful, and noisy equipment within the whole industrial sector.

Processes such as hydro-cracking, distillation, liquefaction, and regasification involve large scale compressors, furnaces, gas-turbines, fan-cooled heat exchangers, and large-scale evaporative cooling systems are well known to be noisy.

Acoustical challenges in petrochemical processes

Petrochemical plants face complex acoustical engineering challenges. Petrochemical processes operate largely outdoors, these operations, which include pumps, compressors, blowers, agitators, and coolers, run out in the open, with limited barriers in place to restrict equipment noise from going beyond the confines of the plant.

These plants, as we said, include large numbers of industrial tools and often moving high volumes of air or gas while operating at really high pressures and temperatures. All these combined means that such areas can be exceptionally noisy. Moreover, the large number and variety of equipment within the plant force plant operators to face unique challenges when trying to find a comprehensive solution for noise mitigation.

With noise control and environmental legislation becoming more stringent and the employee health and safety that stay at the forefront of all processing practices, ensuring that noise is effectively mitigated has become a key concern for process plant operators across the petrochemical and chemical processing sector.

Solutions

Plant operators across the industry should be considering that soundproofing installations are not the same twice, careful consideration must be given to each system’s function, permitted noise levels, and much more to determine the most effective noise control solution for the application. As a result, when it comes to specifying what is the perfect noise mitigation product for on-site equipment in such environments, there is no one-size-fits-all solution and several factors must be analyzed.

Noise control measures for such industrial plant items can be particularly complex to design from an acoustic perspective, given a large number of noise sources. Besides, any housings or anything else that is fitted around the equipment can present significant challenges for the ventilation of the analyzed equipment.

Following an initial consultation path with a leading industrial and environmental noise control manufacturer, is the quickest and most effective way to solve complex noise mitigation challenges.

Stopson Italiana has worked internationally with plant processing engineers and their consulting teams to provide accurate and cost-efficient, site-wide noise assessments and mitigation solutions of industrial sectors such as petrochemical complexes both large and small.

Noise containment in Cogeneration plants

Despite its efficiency and environmental advantages, CHP still has its issues, most notably the excessive noise levels it can produce.

The benefits of cogeneration are well known, with these systems typically cutting costs by around 20% compared to the other existing solutions. CHP can also significantly reduce emissions cost-effectively due to the possibility to be applied to existing energy equipment. Such benefits, combined with the short ROI they can bring, have seen a rise in cogeneration installations.

Due to the increasing spread of CHP plants, noise mitigation has been a key point to meet regulatory and environmental noise requirements.

What are the noise sources?

There are a few components within and connected to the CHP system that can cause noise:

  • Engine
  • Boiler
  • Exhaust system
  • Ventilation systems
  • Fans or radiators
  • Vibration from equipment

A responsible supplier will look at all the various elements in the system to identify the noise source and therefore mitigate that noise. Your supplier should have options for noise attenuation across the system that can adapt to specific equipment needs. Health and safety compliance is paramount as workers need to be in a safe environment that operates to the safest noise levels.
Assigning the entire CHP plant (or at least the main equipment) noise abatement study to a single provider will facilitate a one-stop-shop solution for either the vendor and the operator with the aim of a total peace-of-mind targeted approach.

Noise reduction in CHP systems

When specifying the right noise control products and installations methods for CHP, detailed consideration of the specific system’s functions, location and permitted noise levels, as well as other pertinent factors, is required.

CHP systems should always be paired with some kind of acoustic enclosure which provides total protection against noise by isolating the source. It is important to be aware that the enclosure allows access for maintenance of the CHP unit, which will not compromise any noise mitigation.

Engine

Different engines have different noise profiles and designs so noise reduction must be balanced to that. Your Soundproofing partner should advise you with the noise reduction systems best designed to mitigate either the in-duct and the break-out noise to the targeted residual level at the desired measurement point.

Boiler

Industrial plants, where boilers are used, need an effective degree of soundproofing.
Continuous and intermittent Vents to the atmosphere have to be silenced to the desired residual SPL, but sometimes due to their big dimension and the high Sound Power Level, the boiler structure itself has to be sound-proofed.

Exhaust

Similar consideration must be done for the exhaust system that should be implemented with a separate silencer located in the proximity of the flue. These exhaust silencers must meet the system requirements, without creating an excessive pressure drop as this can affect the CHP performance and efficiency.

Ventilation systems

Noise from the ventilation systems should be reduced by the use of a Silencer. Solutions as Ventilation & Duct Silencers reduce the generator In-duct noise and should be designed specifically for the application and to meet the customer needs.

Fan or Radiators (Auxiliary equipment)

For other equipment such as fans or radiators, often located near the CHP, the soundproofing solution need to be selected appropriately for the target noise rating required.

 

Stopson Italiana solutions for CHP

With an increasing demand for CHP systems across many sectors, stringent noise legislation, together with a general non-acceptance of environmental noise from industrial facilities, the implementation of soundproofing solutions is now a necessity for companies looking to significantly reduce their noise output.

However, as every plant installation is unique, there is no one-size-fits-all solution. Due to the need for detailed analysis, complex custom design, the variability of possible solutions and the regulatory requirements the necessity of a certified and experienced soundproofing supplier has emerged.

Stopson Italiana approach focuses on providing an optimal acoustic response, which satisfies functional requirements with the best price/performance ratio.

Can noise affect workers’ productivity and accuracy?

Loud noise levels in the offshore oil industry torment workers with hearing damage and tinnitus.

Many workplaces have noise levels that are too loud for the human ear. In the long term, a loud working environment can consequently be damaging to your hearing health, therefore it affects workers’ productivity and accuracy.

Offshore oil rigs and platforms are examples of such noisy workplaces. In 2001, more than 800 workers in Norway reported hearing damage or tinnitus as a result of their line of work.

A study from 2009-2011 by PSA, the Petroleum Safety Authority of Norway, shows that 37% of workers in offshore oil productions are affected by damage to their hearing.

The importance of prevention

The National Association of Hearing Impaired in Norway, HLF, underlines the importance of hearing damage prevention and suggests lowering the noise level through usage of acoustic enclosures and silencers.

Organizations need to carefully think about the design of their workplace and how to manage noise levels. The negative effects of noise on employees can have financial impacts comparable with the positive impact of investing in acoustic improvements. Therefore, it makes good business sense to invest.

The impact of noise on performance

The British Journal of Psychology published a study that asked workers to perform two tasks, firstly tested without noise and then with a recording of general noise. The test with noise showed a decrease in the accuracy of their work by almost 67%. This test was made introducing noise at levels there are very low compared to offshore plants’ noise, it’s logic to predict that this percentage would increase when speaking of high-noise environments such as power generation plant or offshore platform.

Noise is very stressful and it can leave workers physically and mentally shaken. Prolonged exposure to loud noises can trigger physiologic stress responses in our bodies, including high blood pressure and an increased heart rate.

Studies show that workers are almost 65% less productive in a noisy work environment than employees who work in much quieter workplaces.

Moreover, HLF underlines that a person with reduced hearing is more likely to become physically exhausted at the end of a workday.

Fundamentals of noise control in Power Generation plant

The science behind the sound mitigation solution applied to power plants.

Soundproofing refers to the processes involved in checking the sound from entering or leaving a specified area by absorbing and/ or mitigating the sound. Soundproofing mechanisms can be employed in several situations, especially industries notorious for sound pollution mostly attributed to the use of heavy-duty machinery, Power Generation plants are part of these.

 

Noise pollution source in power generation plants

There are numerous main sources of noise within a power plant and only a few of the major causes are taken in the exam here.

The sound power level from equipment can spread from about 120 dB to over 155 dB depending on the size and type of machine. There is no easy method to generally categorize one unit as being noisier than another, in fact, the amount of MWs turbine produce does not directly affect the noise they produce. However, diesel engines are more predictable, and generally, the higher the horsepower or kilowatt rating, the higher the noise level because more cylinders and fuel are needed.

Here is a list of some of the common noise source in power plants:

  • Combustion turbine (CT)
  • Heat recovery steam generator
  • Diesel engine
  • Superchargers on diesel engines
  • Steam generators, regulators, by-pass and control valves and piping
  • Air-cooled condensers (ACC)
  • Cooling towers, produce fan and gearbox noises
  • Fuel gas pressure regulating, metering and valve stations
  • Main step-up transformers
  • Condensate pumps, condenser units, and associated piping
  • Piping and pipe hangers not acoustically isolated from structures
  • Blow-off and venting processes
  • Remote water-pumping stations.

The sound emissions from power generation equipment can be reduced by applying noise control devices.

 

Sound Field Definition

To analyze noise from equipment, we need to define the sound field – that is, how the sound will propagate from the equipment or the sources of noise. Near field, far field, free field, and reverberant field are frequently mentioned. These are regions that describe certain characteristics of sound propagation as illustrated in the Figure.

Descriptions according to ISO 12001:2009

  • Near field
    • The near field of a source is the region close to a source where the sound pressure and acoustic particle velocity are not in phase.
  • Far field
    • The far field of a source begins where the near field ends and extends to infinity. Note that the transition from near to far field is gradual in the transition region. In the far field, the direct field radiated by most machinery sources will decay at the rate of about 6 dB each time the distance from the source is doubled.
  • Free field
    • The free field is a region in space where sound may propagate free from any form of obstruction.
  • Reverberant field
    • The reverberant field of a source is defined as that part of the sound field radiated by a source that has experienced at least one reflection from a boundary of the room or enclosure containing the source.

Fundamentals of Noise Control

Noise control or mitigation involves several steps, and the amount of noise reduction is driven by having to meet an environmental noise limit or some regulatory limit, not to mention workers’ safety. A simple model using the classical approach to noise control (shown below) allows the examination of the options for effective and economical noise control:

source of noise → path of noise →received noise

Solutions

Applying noise control involves affecting one of these three elements. Most often it is the ‘path of noise’ that is controlled by the use of acoustic enclosures, barrier walls, silencers, and other similar noise control treatments. This method is the most widely used as the degree of noise control can be tailored depending upon the noise requirements and generally it is the more economical approach. The control on the ‘source of noise’ can be expensive because it may require a complete redesign and retooling process which takes time and money.

For new plants, examine the structure arrangement and locate the noisiest equipment or operations away from noise-sensitive areas. Grouping smaller sources together can be beneficial in that a common noise barrier or enclosure can solve a lot of small problems.

10 Steps to choose the right Soundproofing Materials

Soundproofing Materials: 10 Steps to choose the right one and how to test their effectiveness in the Industrial context.

 

Soundproofing refers to the processes involved in checking the sound from entering or leaving a specified area by absorbing and/ or mitigating the sound. Soundproofing mechanisms can be employed in a number of situations, some of which may include private homes, religious centers, offices, studios, and most especially industries notorious for sound pollution mostly attributed to the use of heavy-duty machinery.

Over the years, it has been discovered that noise pollution has the potential of causing damage to our health than we initially conceived. And as a result of these findings, employers of labor owe their employees good working conditions and a safe working environment, which typically involves a working area that dissipates noise levels below standardized noise thresholds. 

What’s more, it’s common knowledge that a noisy environment negatively affects concentration and attentiveness, and would drastically reduce productivity and the quality of service.

More negative effects

Noise pollution doesn’t stop there, it also targets the psychological health of its victims and can trigger health issues such as high blood pressure, hearing impairments, stress, and insomnia. In truth, the list is inexhaustible. 

Most industries the world over understand the importance of the health of employees, yet cannot afford to get rid of such heavy-duty machinery due to a lack of quieter alternatives. To solve this problem, it is best to lock in the noise that these machines produce by the installation of quality soundproofing materials.

 

Soundproofing Materials and How They Work

As was earlier stated, soundproofing simply refers to mitigating the noise within a certain area. This is achievable by installing certain materials (insulators) that trap sound and absorb them. 

There exist different types of soundproofing materials and you’d need to consider a lot of factors like the kind of building to be soundproofed and the intensity of noise to be absorbed among many other factors.

Here are a few soundproofing materials used in for industrial soundproofing applications:

 

  • Mineral Wool (Rockwool Rockboard)
  • Soundproof Fiberglass (Owens Corning 703)
  • Acoustic Fiberglass.
  • Acoustic Foam Panels.
  • Echo Absorber™ Acoustic Cotton.
  • Fabric Wrapped Acoustic Panels.
  • Fire Rated Foam. 

 

Ten Steps towards choosing the right soundproofing material

 

There are no wrong materials when it comes to soundproofing, it really just depends on what you aim to achieve. We have, however, come up with 10 guidelines to be followed when choosing soundproofing materials in order to get the best out of soundproofing.

 

 

 

  • The level/Source of Noise: The level of noise that is to be locked out or in, goes a long way in deciding the kind of materials to use. For minimal noise, soft, specially designed foams can help to absorb the noise, but for noise emanating from heavy-duty machinery, more advanced noise insulators may be adopted.

 

  • Propagation of Noise: Noise can either be airborne or structure-borne. To get the best materials for soundproofing, you would need to first determine how the noise travels from the original source to the receiver. This is because some insulators are suited for airborne noise transmission and may be quite ineffective for noise that is structured-based and vice versa.

 

  • What are these materials are made of: Some soundproofing materials are more eco-friendly than others, and should generally influence the choice of materials. Some others may include flammable agents which may not be suitable for certain applications.

 

  • Thermal Insulation: Some soundproofing materials carry with them some thermal insulation features, which helps to reduce heat also. It is advisable to get these types of soundproofing materials for cost-effectiveness and the added advantage, especially in an industrial setting.

 

  • Ease of Installation and Maintenance: When choosing soundproofing materials, it’s advisable that opt for the ones that are easier to install for time maximization. For example, when decoupling walls and ceilings to keep sound front traveling through them, it is best to make use of the resilient sound clips instead of resilient channels because they are easier to install.

 

  • Why are you soundproofing? In choosing the right materials, you must understand the purpose for which you are soundproofing in the first place. If the aim is to lock sound in, you should not consider soundproofing materials like the mass loaded vinyl which is specifically designed to keep sound out.

 

  • Additional soundproofing: If you are looking to cover the loopholes that may remain after general soundproofing, you should consider getting additional soundproofing such as the under door draft stopper as it seals the small gap between the bottom of the door and the floor, and ensures that there are no under-door spaces that could let noise penetrate or escape.

 

  • What parts of the area are most important? You should also determine what parts of the noise prone workspace you want to focus on when soundproofing, as this will help to decide the kind of materials to look out for. For example, the weather stripping can only be used to seal gaps around doors and windows, hence it should not be considered for soundproofing walls.

 

  • The best material wins: It is of paramount importance to purchase the best quality materials affordable. You can seek expert opinion in deciding what materials are of the best quality based on your proposed applications. Low-quality materials will only bring you discomfort in the long run and in some cases a potential industrial hazard.

 

  • Soundproofing windows: When soundproofing windows, the use of double-glazed windows may fail miserably to effectively mitigate noise pollution, hence, you may opt for thick glass as a more functional alternative. The thicker the glass, the better the results. 

 

How to Test the Effectiveness of Your Soundproofing Materials 

To ensure that you are purchasing the best and most effective soundproofing materials for your industry, it is best to run a series of tests. Here are some methods to employ in testing the effectiveness of soundproofing materials:

  • Making use of Impedance tools: The impedance tube is pretty much a tube with circular ends. There are different types based on size, shape, and material used in making it. This tube can be used in free field situations to test the transfer of sound in a bid to understand the specific soundproofing needs.

 

  • The impact insulation class: This is used to test sound-blocking floor soundproofing products. There are other products such as the impact insulation class that test other soundproofing efficiency of other parts of a workspace. 

 

  • If your industry related noise challenges require that you test how effective sound-blocking materials are for ceilings and walls, you may use the CAC and STC respectively.

 

  • For sound absorption material testing, the NRC is your best method. NRC is the comparing of different sound absorption levels through the use of speakers and microphones.

The main item is represented by a system of n.2 auto-cleaning filters, designed taking into consideration the high presence of dust in the site. In addition to this, n.2 Duct silencers, n.2 Acoustic Enclosures, and n.4 Discharge Silencers complete the project.

These latter are the ideal solution for noise reduction caused by gas pulsation in refrigeration and air conditioning systems.

The multidisciplinary nature of the project has been turned into a challenging research and design work, carried out successfully by the Stopson Italiana engineering team. Indeed each component has been customized in order to be assembled and working in non-ordinary climatic condition. It is also noteworthy that Stopson Italiana has been designed as responsible both for the release of the electro-instrumental parts and the control panels of the system.

The project – of which the installation is underway in these days – consists in the following units:

  • 2 Filter house pulse jet type for a flow of 172189 Nm3/h
  • 2 Inlet and Duct Silencer from filter house to blowers
  • 2 Acoustic Enclosure for blowers
  • 4 Exhaust Silencers on blowers discharge

The acoustic warranty covers 82 dbA SPL, at 1m from each unit supplied.

 

This Sulphuric Acid Plant is a part of a contract that represents half of the total Fertilizers Complex built at Ain Sokhna, which is the biggest complex ever built in the fertilizers sector in Egypt.

The project aims to cover the local market’s fertilizer needs and export surplus production. The cluster includes n.9 major factories with a production capacity of 1m tons/y of phosphate and compound fertilizers, Di-Ammonium Phosphate (DAP) and pure and commercial phosphoric acid. The whole plant has been implemented by three companies specialized in building the largest phosphate fertilizer factories in the world using Italian, Spanish and Chinese technology.

With this recent achievement, Stopson Italiana re-confirm its capability to provide “one-stop-shop option” for complex equipment packages covering the entire range of product related to air inlet and filtration system, soundproofing solutions for either in duct and break-out noise and control system implementation.
