Reducing Noise In Industrial Environments
There are several ways to reduce or limit exposure to hazardous noise in industrial environments. The first option is to eliminate the noise source, but in many cases, the noise source is essential to business operations. The next option, and where DDS Acoustical Specialties comes in, is developing a soundproofing system that reduces the noise created by sources.
When we develop systems, we think about the basic principles of noise control: sound insulation, sound absorption, vibration damping, and vibration isolation. We achieve success through a combination of products and custom solutions. In many cases, we enclose equipment to reduce noise at the source and use sound absorbing material to prevent the spread of noise.
Occupational Noise Control
Occupational noise, also known as industrial noise is often a term used in occupational health and safety. This noise needs to be regulated in the workplace and have corrective steps documented to protect employees in the workplace from excessive exposure. Specifically, employees who encounter continued excessive noise levels might develop hearing loss and high-stress levels along with compromised safety issues. Occupational noise is a hazard traditionally linked with loud industries such as manufacturing and construction but can be present in any workplace.
Occupational safety organizations recommend that the maximum exposure to noise is 40 hours per week at 85 to 95 decibels (dB). For every additional 3dB, the maximum exposure time is reduced by a factor of two. Sometimes, a factor of two per addition 5dB is used, however these occupational regulations are acknowledged as inadequate to protect against hearing loss and other health effects.
Outdoor Noise Control
Outdoor noise control or Industrial non-occupational environmental noise is the sound that are transmitting from your business to neighbors. Compliance is typically defined by attenuation requirements or noise impact at a critical receptor point or at the property line. Regulations usually specify a maximum outdoor noise level of 60 to 65dB.
The noise source may be construction activities, manufacturing/production operations, or upset condition alarms. Agencies governing this type of noise are typically at the local level, but this can vary by state and municipality. Typical ordinances include:
- Allowable noise levels during daytime or nighttime hours
- Classification of areas into residential, commercial, or industrial
- Defined decibel levels deemed to be acceptable for each category
Methods for Industrial Noise Control
One of the most effective and logical approaches to noise attenuation and industrial soundproofing is to install systems that minimize noise from the start, using control techniques such as:
- Damping – A method of reducing noise levels from chutes, hoppers, machine guards, conveyors, panels and more
- Selecting efficient equipment – Selecting fans, compressors, PD blowers and engines that operate efficiently contribute significantly to noise attenuation
- Adjusting Fan Speed – Fan noise is in direct correlation with fan speed, so simple adjustments can produce significant results
- Controlling high-pressure steam, natural gas, and other vent noises
- Attenuating noise from process exhausts with stack silencers
- Acoustically treating fans, blowers, and ventilating equipment
- Closing openings in enclosures and barrier walls required for utilities
Addressing Limitations and Customer Needs
In many cases of industrial noise control, everything is a tradeoff. Sometimes a machine needs a certain amount of airflow, viewing or access. We design systems that accommodate all of these needs while provide premier acoustical performance.
This can be defined as the ability to access the machine for maintenance, or access for ingress or egress of raw or finished materials. If an acoustical solution in any way hampers or gets in the way of personnel who need to be near the machine at times, then it is not a successful application. Whether it’s removing waste material or performing regularly scheduled preventative maintenance, simple and easy access to the machine is critical to productivity.
Acoustical glass view windows and high STC clear vinyl noise barriers are ways that visibility can be introduced into an enclosure or barrier wall. From a process point of view, visibility allows operators to monitor equipment without having to enter the enclosure, thereby eliminating the benefit received from the enclosure itself. It can also be important for maintenance regarding regularly scheduled maintenance. Most importantly, from a safety point of view, it allows monitoring of process parameters that unmonitored could cause or become a safety hazard.
All types of manufacturing equipment are powered by a few very specific types of power. Most common of course, is electricity. Second might be fossil fuels such as gasoline, diesel fuel, natural gas, or propane. Some systems are run pneumatically. Of course, this air pressure has to be generated somewhere.
Most of these types of fuel systems generate more than just power to run machinery. Most also generate heat. Some generate exhaust gas. These typically need to be ventilated from the enclosure system. Since any leak or gap can seriously compromise the performance of the enclosure, it’s important to devise a system of ventilating the space without allowing noise to leak as well.
While many of our smaller industrial noise and acoustic solutions are relatively simple and can be installed by maintenance crews or other in-house personnel, larger more complicated systems will need to be installed by crews with specialized skills and the ability to ensure the acoustical integrity of the enclosure. DDSAS can provide the expertise required to ensure that the enclosure performs as originally designed. With a vast working knowledge of the materials used in today’s noise control world, we can make sure that your company is getting the best “dB reduction per dollar spent” for the project.

Dalkia Aegis, EDF Group
Dalkia Aegis, EDF Group is a nationally renowned supplier of cogeneration units capable of providing heat and electricity in one extremely efficient platform. Operational advantages over traditional heat and electricity sources have led to continued growth over the past 35 years. Having outgrown their facility at 55 Jackson St. in Holyoke, MA, they turned to a historic old building immediately adjacent to their existing facility. Built in 1880, the building, while neglected, showed promise. Throughout the course of 2020, the building was reclaimed and soon showed how beautiful and functional the old mill building could become.Read More
