NOISE ENGINEERING DESIGN
When hearing protection and administrative controls cannot be employed to reduce noise exposures, EI’s engineering team assists our industrial clients in the identification and design of noise engineering controls. Engineering controls for excessive noise can be developed for isolated pieces of manufacturing equipment or entire industrial process lines. Initial steps require performing sounds level facility surveys and personnel noise dosimeter monitoring of manufacturing personnel by experienced industrial hygienists. Noise monitoring results are utilized to determine specific sources of excessive noise, as well as the mechanism of sound generation/propagation emitted by the excessive noise source. Multiple sources of noise will subsequently be “rank ordered”, which will allow for a range of possible engineering controls, typically addressing the loudest sound sources first. EI’s professionals segregate excessive noise sources into two distinct classes, vibrational noise and noise turbulence.
Once all specific noise sources are identified, EI utilizes the following logical approach to determine the optimal systems to reduce/control excessive noise:
- Substitution of equipment (fundamental first step)
- Categorization of source into vibrational noise and turbulence-based noise
- Reduction of driving forces which cause excessive noise
a. Decreasing machine speed
b. Maintaining dynamic balance
c. Provide vibrational isolation
d. Increasing impact duration, while reducing the force of impact
- Reduce response of vibrating surfaces
- Reduce area of vibrating surfaces
- Reorienting directional noise sources
- Reduction in velocity of fluid flow (air ejection systems, valves, vents and piping)
- Provide sound absorption alternatives
- Design and installation of equipment and personnel noise enclosures
Let EI’s team of industrial hygienists and engineers work collaboratively to identify and provide cost-effective engineering solutions aimed at reducing exposure of your workforce to excessive noise.

Convincing employees and management to embrace corporate cultural change is certainly nothing new. One needs to look no farther than the successful business models which promote occupational safety, aimed at lowering workplace accidents! A successful occupational safety program requires a cultural change and encourages participation among the entire workforce. Just like safety, promoting a sustainable culture at work is simply good business and yields a significant, long-term ROI.
On July 1, 2021, Virginia Senate Bill 410 came into effect. This legislation, which was passed in 2020, requires school boards in Virginia to develop and implement a water management program for the prevention of Legionnaire’s disease at each public-school building in the various public school systems throughout the Commonwealth.
The Occupational Health and Safety Administration (OSHA) has implemented stringent regulations when identifying confined spaces in the workplace. Such standards are due to the number of fatalities associated with occupying these spaces.
The era of leaded gasoline has finally come to an end. Yes, you read that correctly. Leaded gasoline is finally no longer being used anywhere on the planet. Environmental activists, government regulators, and people with common sense are happy to see the poisonous additive is no longer used.
We recently discussed how to minimize the spread of the highly contagious Delta Variant in the workplace with Rapid Antigen Testing. As more businesses return employees to the workplace, whether it be to manufacturing facilities or commercial office spaces, it remains critical to keep everyone safe and healthy. Absenteeism driven by the need to quarantine both COVID positive employees, as well as the general workforce with whom they closely interacted significantly impacts productivity.
As record heat waves continue to scorch throughout the U.S this summer, it is important to know the dangers and warning signs of heat stress. While temperatures climb during the summer months, the increase risks of heat- related illnesses or HRIs, increase as well. According to a study by the CDC, approximately 90% of heat related deaths occur during the months of May, June, July and August.
How to Combat the Highly Contagious Delta Variant in the Workplace: Rapid Antigen Testing – A Game Changer
As the highly contagious delta variant spreads across the United States, a surprising number of vaccinated Americans are testing positive for COVID-19. The promise of a “return to normal” has hit an unexpected roadblock with the growing risk of these breakthrough infections. According to an early new study, individuals infected with the delta variant may carry more than a thousand times more virus particles, testing positive up to two days earlier than those infected with the original SARS-CoV-2.
Once the workforce has been recruited for the challenge, your sustainability program is ready for the next step: building sustainability into your company’s brand! It is well documented that sustainability sells. 66% of all consumers indicate they would pay a premium for a product if it came from a sustainable brand, with 70% of millennials having a similar view. More significant, 90% of CEOs feel that sustainable brands are key to success in business.
Have you ever wondered why there’s an insignia of a trout stamped on the top of stormwater drains? If you’ve never noticed this, take a look the next time you happen to see one on a sidewalk or in a parking lot. It’s probably not hard to guess the reason when its printed directly on top, but most people are unaware that those drains lead directly to our streams and rivers.
Since the Environmental Protection Agency’s (EPA) Risk Management Program (RMP) rules were first promulgated, the efforts to revise, improve, or otherwise change these rules has been like a slow-motion tennis match. The latest volley was a significant forehand shot to the back corner of the opposing court.
