Industrial
Sound Barriers
Used in many occupations and situations, industrial sound barriers combat noise pollution by absorbing and reflecting sound. A noisy workplace can be hazardous to the health and safety of employees. It can also affect the public, especially when construction is taking place nearby.
Many people don't realize what a serious problem noise pollution poses. It can lead to a host of issues, including hearing loss, tinnitus, physical and mental stress, accidents, and injuries. Exposure to noise can also interfere with productivity, concentration, and communication, adversely affecting workers on the job and in their personal lives.
According to the National Institute for Occupational Safety and Health (NIOSH), 22 million people per year experience loud noise in the workplace. Their study on occupational noise exposure within US industries and occupations found that "hypertension, elevated cholesterol, and hearing difficulty are more prevalent among noiseexposed workers." NIOSH considers noise at or above 85 decibels to be hazardous. and recommends sound barriers as a solution for reducing noise exposure on the job. Businesses spend an average of $242 million on workers compensation claims related to hearing loss, so it's important to provide sound barriers for the sake of your business as well as your employees.
If your employees can potentially be exposed to noises that are at least 85 decibels over eight working hours, OSHA requires you to put a hearing conservation program into effect to help prevent hearing loss through reduced noise exposure. OSHAs Noise Standard requires employers to do so through administrative controls, engineering controls, or Hearing Protection Devices.
According to the Centers for Disease Control and Prevention (CDC), if an individual must raise his or her voice in order to speak with someone who is just three feet away, noise exposure is at a limit that is considered harmful. More than ten million construction workers are exposed to excessive noise every day, with 14 percent suffering from job-related hearing difficulty. Much of the equipment used in construction exceeds 85 decibels. This problem is also found in demolition work, mining, manufacturing, agriculture, and many other industries.
How Can You Prevent Noise Pollution in the Workplace?
Justrites construction site acoustic barriers reduce the perceived noise level of loud equipment and machinery by up to 50 percent
Industrial sound barriers help prevent noise from affecting the quality of life of your workers and the public. In some areas, they may also help comply with city noise regulations. Though noise ordinances can vary from city to city, they generally set a limit for allowable noise levels during different periods of the day, with higher levels during standard working hours and lower levels at night. When the noise ordinance is violated, it can result in fines for your business or even a temporary work stoppage, costing you time and money.
Sound barriers can help prevent this. Without them, your business might have to switch to smaller, quieter equipment, which will likely extend the amount of time it takes to complete a job. Justrite offers versatile sound barriers that are easy to transport, install, and store, ideal for use on construction sites, industrial plants, civil engineering sites, mining sites, and more. Sound barriers should be used around any equipment that can affect the hearing or potential safety of your workers, including noisy air conditioners, generators, compressors, and jackhammers.
OSHA lists sound barriers as an example of an engineering control that is both effective and inexpensive. While other solutions can result in inconveniences on the job, sound barriers are a simple way to protect your workers and the public while continuing business as usual. If your employees are forced to use smaller equipment, only use noisy equipment when less people are around, or limit the amount of time they spend near that equipment, it can result in delays and unhappy clients, affecting your business's profits and reputation.

Temporary Noise Barrier Walls to Protect Workers Hearing
Justrite QuietSite industrial sound barriers make it easy to control noise at any workplace or job site, while being much less disruptive to your employees' workflow than many other solutions. It's important that workers be able to communicate with others. Hazardous noise levels make this incredibly difficult and can lead to accidents or injuries on the job. Industrial sound barriers are a simple solution to reduce noise pollution. They can improve the well-being of your employees and the public while helping you meet city noise regulations and avoid fines, complaints, and delays.

We all get stuck in bumper to bumper traffic whether it is to commute to work, head out for vacation, or to go to popular events. When you are sitting in traffic, you probably think about the sights and sounds around you.
If you travel long distances or are frequently on the highway, you may also notice one or several types of noise abatement solutions in the form of large walls aligning the roadway.
Have you ever considered why there are different types of sound walls and if they even work?
How Highway Noise Barriers Work
Believe it or not, highway noise barriers and sound walls are the subject of many federal, state, and local studies and discussions.
Traditionally, these blockades use metal, brick, concrete or wood to minimize the loud noises generated by highway traffic.
These highway sound barrier walls are important to keep offensive freeway sounds from penetrating local neighborhoods and business districts. Studies show the first attempts at blocking the sound creates a couple of problems.
First, the materials used did not sufficiently lower the sound levels in the targeted areas. Highway walls that are not sufficiently tall allow the sound to go over the top of the barrier.
Second, using sound-reflective concrete walls on both sides of the highway often causes the noise to reverberate or bounce back and forth across the Interstate. The noise levels can increase or become higher in frequency when this reflection effect happens.
This is why outdoor noise control is important with residential and commercial businesses being located so close to heavy traffic areas.
Disadvantages of Concrete Highway Barriers
Newer research proves concrete sound barrier walls are some of the worst offenders for creating unwanted and unpredictable reflected noise issues.
The sound waves hit the wall and the reflective surface of the concrete causes the sound wave to go in the opposite direction.
Excessive Noise Contributes to Numerous Health Problems
Sound wall construction with acoustic panels help reduce high and low-frequency noise levels that contribute to these health problems. Advancements in noise testing and sound dampening materials offer a tremendous advantage for local municipalities and government entities.
Instead of attempting to block the sound or bounce it to a less populated area, noise dampening materials like mineral wool between layers of perforated fiberglass diffuse and absorb much of the unwanted sound.
Such sound-absorptive panels kill the noise by making the sound wave use up its energy as it passes through strategic openings in the wall.
Benefits of Highway Noise Control
Additional Benefits To Highway Sound Barriers
Absorptive panels are pre-engineered and easily customized for each site and application. Walls designed with the best materials have protective UV coating and will not rust, rot, or deteriorate in extreme temperatures.
Since these walls use lightweight materials, they work extremely well for areas with weight restrictions.
Conversely, concrete noise barriers are dense, hard to recycle, and not mobile. Studies show a sound wall are more effective sound-reflective sound barriers.
Such innovations ensure freeway sound walls reduce sound levels and provide a cost-effective solution to highway noise pollution.
