Basics of Damping Techniques to Control Noise

Reducing noise pollution is key for most construction sites. Reducing sound not only benefits the surrounding community, but also, on-site workers. Noise pollution might lack the visual impact of growing landfills and dwindling environment does for other types of pollution, but it too has a lasting impact.

There are various methods, which when employed, can greatly reduce the amount of noise produced. At IES-2000, we are your noise reduction specialists. Whether employing a vibration damping sheet or suggesting other vibration dampening materials, we are the answer to unwanted noise. Reach out to us today and find out how we can help your company.

Damping Techniques

One of the most effective ways to cut noise is by controlling vibration. Damping is the best-known vibration controlling technique. It converts vibrations into heat, thus eliminating the energy created by vibration. When the vibration is eliminated, so is the noise.

Where is Damping Most Commonly Used?

Rubber mounts are typically employed to dampen the sounds created by vibration. Acoustic damping material can be found in various locations throughout a construction site. Vibration sound concerns can also be found in the medical community, and business arenas. Some of the most notable places are included in the list below.

• Equipment Cabs
• Engine Compartments
• Various Enclosures
• Floor Systems
• Ceiling Systems
• Home Appliances
• Heavy Duty Equipment
• Medical Equipment.

Why Noise Damping is Vital

Vibrational noise from a consumer point of view can become problematic and bothersome. No customer wants an incredibly loud dishwasher or washing machine. There is another reason too. Long-term vibrational noise can make mechanical structures unstable and weak due to structural fatigue.

How to Combat Vibrational Noise

When companies manufacture their mechanical structures, it is important that they realize the issues that come with vibrational noise. There are typically two types of damping systems to utilize. They are listed below:

• Free Layer Damping
• Constrained Layer Damping

In industrial, medical, or aerospace, constrained layer damping works quite well. Free layer damping is somewhat limited, but very practical in certain applications.

Free Layer Damping

The easiest to apply, free layer damping can also add considerable weight to the product. One example of this is the automotive industry. Polymer is typically used to coat metal, to absorb the vibration0. This type of sound dampening is also recommended for lightweight structures.

Constrained Layer Damping

For heavy applications such as floor or ceiling structures Constrained Layer Damping is recommended. It also converts vibration to heat diminishing the sound.

Whether new to noise pollution reduction technology or a seasoned expert, IES-2000 is here to answer questions and to create real-world sound reduction solutions. Utilizing the latest vibration damping sheets and other acoustic damping material, IES-2000 has the perfect solution.

Minimizing the Impact of High Noise at Construction Sites

Noise pollution is a real concern. It can come from a variety of sources including loud music, highway traffic, and construction sites. While it might not be something that comes to mind, unless you live near the source, it poses real health dangers. It has been documented, by several University studies, loud noise can not only raise blood pressure in adults.

Noise is an unfortunate bi-product of the construction business. The good news is there are various ways to cut down the noise levels at the job site. Outdoor sound barrier panels are just one way.

What Are Some of the Effects of Noise Pollution?

While many people might realize long-term exposure to noise pollution could potentially damage their hearing, many fail to realize there are other issues as well. The three biggest concerns of noise pollution are listed below.

• Hearing Loss
• Negative Long-Term Health Issues
• Lost productivity

Noise induced hearing loss, or NIHL, can occur when exposed to high levels of noise. The damage is irreversible and permanent. Long-term health issues can include heart disease, high blood pressure, stress, and sleep disturbances.

Ways to Control Noise

There are generally considered two ways to help control noise.

• Engineering Controls
• Administrative Controls

Engineering Controls to Reduce Sound

• Utilizing Low-Noise Machinery
• Proper Machinery Maintenance
• Utilize Sound Barrier Walls

Administrative Controls to Reduce Noise Levels

• Operating Machinery When Fewer People are Around
• Limiting Amount of Exposure to on-site Personnel
• Offering Areas Where Workers Can Get Relief from Noise Levels

Ways to Reduce Job Site Noise

While it may seem like a massive undertaking, with IES-2000, we can walk you through the best ways to manage noise. Listed below are several important considerations:

• Cover Metal Wheels with Rubber
• Use Outdoor Acoustic Barrier
• Use Sound Absorbing Material
• Maintain Equipment

Covering metal wheels, tables, and other equipment, with rubber, can greatly reduce the amount of impact noise produced. On-site modification of metal parts can reduce rattle and vibration. Using outdoor sound barrier panels greatly reduces the amount of noise exposure to both workers and the community. Wood, metal, and concrete surfaces should be covered with absorptive material to cut down on the amount of sound reflection.
