SysTech is experienced in developing industrial noise control strategies that meet OSHA and NIOSH regulations for a wide range of industrial environments and manufacturing sites. Noise is a big problem that companies need to keep working on, whether it’s inside a building and affecting the workers or outside a building and affecting the people who live nearby.
Read about our noise attenuation techniques, the products and systems we use, and the manufacturers we most commonly work with.
“Noise in an industrial environment can be a difficult, but necessary, problem to tackle. SysTech has the experience and products to achieve regulatory (OSHA) and/or municipal compliance to noise regulations and ordinances.” – Matt Glover 2009
Occupational & Outdoor Noise Control
Occupational noise is regulated in the workplace and corrective steps are documented to protect employees in the workplace from excessive exposure. Specifically, employees who encountering continued excessive noise levels might develop hearing loss and high-stress levels along with compromised safety issues.
Industrial non-occupational environmental noise compliance is typically defined by attenuation requirements or noise impact at a critical receptor point or at the property line. 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
How does SysTech address these potentially adverse acoustic issues?
Methods for Industrial Noise Control
Noise attenuation is achieved by decreasing the intensity or volume of sound in a controlled environment. There are many noise reduction strategies that can be employed in industrial settings. One of the most effective and logical approaches to noise attenuation 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

Noise and Vibration Control Engineering Services
Knowing and defining the noise intensity, those impacted by the noise, and who is requesting noise controls be put in place are all essential parts of a noise control solution. It is critical to determine the extent of the noise issue before formulating an attenuation scheme.
And it is important to remember that when a single piece of machinery needs to be attenuated, knowing the other noise producers in the vicinity and the building construction impact the final noise solution.
Some of our services, offerings, and tasks include:
- Noise modeling
- Analysis and attenuation of “noisy” machines and process equipment
- Noise and vibration engineering design, research, and control
- Sound intensity measurements
- Sound power measurements
- Plant noise surveys
- Community noise surveys
- Rotating equipment measurements
- Structure-borne noise and vibration analysis
- Noise source analysis and control
- Noise source identification and measurement
- Zoning compliance measurements
- Noise barrier design
- Occupational noise measurements
- Noise enclosure design
- Personnel sound booths and control room design
Industrial Noise Control Products and Systems
The environmental impact caused by industrial processes such as vent blow-offs, rooftop fans and HVAC equipment, chillers, cooling towers, oil and gas building ventilation systems, power gen engines, and other noise generating processes can be addressed by installing various types of noise abatement equipment. We partner with the leading manufacturers of industrial noise control products and systems to offer a broad range of reliable industrial noise control solutions.
Industrial Fan Silencers – Fans are found in almost all industrial applications and can be large contributors to the problem of industrial noise. Exhaust and supply fan silencers can significantly reduce noise in both indoor and outdoor environments.
Acoustic Louvers – Where ventilation air is required, addressing noise concerns from a processing area within a building or machinery noise mitigation from a facility, acoustic louvers are a proven means of attenuation.
Industrial Exhaust Silencers – In addition to selecting the right noise control equipment, SysTech will access the entire noise attenuation application and reduce the overall sound level. Process silencers are applied to PD blower and compressor exhausts, stack discharges, and the venting or blow-off of high-pressure gases.
Noise Control Enclosures – Engineered acoustically for superior noise control, sound enclosures are an extremely effective means for containing industrial equipment noise.
Duct Silencer – Where noise radiates from a ducted system or enclosure, duct silencers are typically applied with success.
Acoustic Building Ventilation Systems – When very high equipment noise levels are present in a building caused by large compressors, engines, generators, and motors, and heat removal ventilation systems are required, SysTech offers customized acoustic ventilation systems to meet both ventilation and noise reduction requirements.
Duct Lining – Ventilation systems using acoustic absorbent material such as foam or fiberglass will effectively decrease airborne noise.
Vibration Isolation Pads – Vibration control, employing anti-vibration machine mounts such as springs or neoprene will reduce transmission of noise created by vibration.
Acoustic Flexible Connectors – They serve a dual purpose in containing noise generated by the fan blade rotation and that induced by vibration.
Acoustic Blankets/Wraps – Attenuate noise from the equipment casing with high-density sound blankets.
