Removable Insulation Jackets for Sound Attenuation

Written by Brian Bannon & Michael Bannon, co-founders of Thermaxx Jackets

Sound Attenuation Photo 1Sound has its place in our lives. Can you imagine a quiet police or fire siren? Going to a concert and having to be quiet to hear the music? How about being able to hear crickets when a walk off home run is hit during a postseason baseball game? No! Sound & noise aren't always unwelcome in our lives.

However, sometimes sound does not have a place and does not belong. Such as when you're trying to repair your steam boiler and the PRV above your head sounds like a 747.  Perhaps you're on a conference call and the machine on the other side of your office's wall sounds like it is jackhammering the wall to pieces.

This is a problem when the machine has a touch temperature of 200f. Rather than a sound problem, we now have a potential fire. Fortunately, there is a solution!

Identifying Hazardous Noises in Your Facility

Once you notice a loud sound in your facility, it's hard not to hear it. You will frequently hear these noises, even if you are not quite sure where they are coming from. To get the right sound attenuation insulation, you'll need to pinpoint the source of the noise.

Look at common culprits, such as:

  • Piping systems
  • Turbines
  • Pumps
  • Industrial fans

These may be some of the loudest components in your facility. Consider analyzing the decibels and frequency levels in hertz. Once you identify what part of your equipment is causing the noise, you can find a suitable sound attenuation solution to fix it.

Sound Attenuation Solutions and Materials

Many types of sound attenuation solutions and materials can help you isolate and reduce loud noises. Panels, absorbers, curtains, and blankets are four of the most common types.

You could try open-cell foam panels to dampen the sound. These panels work best for noises in the upper hertz ranges. You could also try a sound attenuation blanket instead, which can incorporate multiple types of sound dampening materials.

Insulation blankets can often cover a more full range of hertz frequencies and offer heat and sound insulation. At Thermaxx, we make custom-fit versions for your specific equipment needs.

Removable insulation can now be built with layers of insulation, facing the machines, to reduce the heat with each layer of insulation. Insulation thickness is designed to reduce the temperature to allow for sound deadening material (Mass Loaded Vinyl or Silent Tread) to be installed.

Currently, we offer Jacket 1, which is an interior jacket designed for sheltered areas that are not exposed to the elements. Jacket 2 is for outdoor conditions and is hydrophobic.

Benefits of Using Sound Attenuation Blankets for Pipes and Other Components

Using sound attenuation blankets for pipes and a multitude of other components offers numerous advantages, ranging from reducing noise levels to improving the workplace. Some benefits include:

  • Increased employee productivity
  • Better communication throughout the facility
  • Less worker fatigue
  • Compliance Occupational Safety and Health Administration (OSHA) standards
  • Enhanced employee protections
  • Reduced compressor and motor noise
  • Easy removal for maintenance and equipment servicing
  • Greater comfort for workers and tenants

Our sound attenuation insulation will help you achieve a better, safer space by dampening noise with the added benefit of temperature control.

Tips for Proper Sound Attenuation

Choosing the right sound attenuation blankets for pipes and other equipment is important. Keep the following tips in mind:

  • Knowing the sound frequency will help in determining the proper material choice for sound attenuation.
  • Know that if you choose panels, they need to be butted together to reduce sound leakage.
  • Mount equipment to a vibration isolation mount or pad to reduce vibration.
  • Invest in high-quality silencers and baffle chambers.
  • Consider the area around the equipment and opt for attenuation blankets if space is tight.

Why Hazardous Noise Reduction Is Important

While everyone is exposed to some noise in a public workplace, certain aspects of some jobs can make sound an even larger issue. People who work in factories, manufacturing facilities, construction zones, and many other occupations are often exposed to loud noises that can cause permanent hearing damage when left unchecked.

As a result, OSHA has issued guidelines for noise reduction in facilities throughout the U.S. If noise exposure at your facility is above an average of 85 decibels over eight working hours, in order to be in compliance you will need to start a hearing conservation program.

Attenuation insulation can play a vital role in your hearing conservation program. This insulation helps reduce noise levels, allowing you to abide by OSHA safety and compliance codes to keep your workers safe.
