Acoustiblok® “All Weather Sound Panels” Installed to Quiet Conveyor Noise at George Bush International Airport
HOUSTON, Texas, February 16, 2011 – Controlling conveyor noise at the George Bush Intercontinental Airport in Houston became a serious issue when airport TSA staff complained that the clamor emanating from a conveyor system near their station was making communication impossible during normal work routines.
Vanderlande Industries U.S., Inc., who installed the conveyor system at the airport in 2004, was asked recently to correct the noise problem six years after the conveyor system went in.
In November 2010, Vanderlande contractors installed Acoustiblok® “All Weather Sound Panels” in the space between the conveyor and the TSA work area, immediately deadening the conveyor-caused sound reverberations and allowing TSA workers the ability to speak and carry out their duties without interruption.
Carl Morris, senior project manager for Vanderlande Industries, said the Acoustiblok panels created a significant improvement in the work area for airport staff.
“The Acoustiblok is doing a great job, they can hear better and talk to each other at a much more normal level,” Morris said.
Conveyor systems like the one used in the George Bush Airport to move baggage from the terminal to aircrafts, are notorious sources of non-stop noise. On any conveyor system, for instance, factors such as speed and the number of moving parts affect the decibel level (dBA) of the sound.
Normal conversation is about 45 decibels. Various conveyors operate at different decibel levels, depending on type, construction, use with other equipment and placement in a facility. Many produce noise in the mid-70s to low-80s decibel range, according to material-handling sources. OSHA's noise limit is 85 decibels at ear level.
The conveyor at George Bush Airport was emitting noise levels that, while not high enough to be damaging to the staff’s hearing, were high enough to interfere with normal levels of conversation.
Some acoustical barriers prevent transmission of sound between the noise source and the employee, but the sound is reflected back toward the source instead of being absorbed. As the heavy, limp Acoustiblok material vibrates from the sound, it actually “transforms” the acoustical energy into “inaudible friction energy.”
Airport officials all over the world are working to find ways to reduce high noise levels in their terminals. The new, $150 million Sikhuphe International Airport in the Kingdom of Swaziland in southern Africa addressed the problem in advance by designing Acoustiblok into the terminal’s construction.
Acoustiblok has been proven effective in reducing industrial and transportation noise exposure. This type of noise often exceeds limits recommended by the World Health Organization and contributes to noise-induced hearing loss.
Adding a 3mm layer of the UL-approved Acoustiblok increases a standard stud wall’s soundproofing factor by more than 98-percent. Lead, previously considered the best soundproofing, works on precisely the same basis with the same STC sound reduction rating.

Acoustiblok sound abatement material was used to seal noise leaks in the massive doors of the historic film studio, in time to begin shooting "City of Ember," starring Natalie Portman and Bill Murray.
Belfast, Northern Ireland -- Belfast’s Paint Hall Studio, Europe’s largest film studio located in the historically renowned Titanic Quarter of the city needed to dramatically reduce outside noise pollution from entering its massive sets in time for its biggest
film production to date.
The pressure was on to find a solution to the ambient noise from nearby construction, heavy traffic from a main road, and overhead aircraft infiltrating the massive 31,000 m³ (1,094,755 cubic ft.) structure.
Before it was a film studio, Paint Hall was part of Belfast’s historic Harland & Wolff Shipyards, where the Titanic and other ships were built. Ship Hall was used for painting huge portions of ships in climate-controlled conditions.
While the studio’s double skinned cell construction combats general noise pollution on set, the building’s massive 75ft (23m) doors were found to be leaking sound.
These problems needed to be corrected before filming could start on a new project, a joint Universal Pictures/Northern Ireland production starring Natalie Portman, and the result had to be effective enough to satisfy the sensitive microphones used in
filmmaking, which easily pick up background sound.
Consultants from Acoustiblok UK Ltd conducted a site visit and compiled a comprehensive report identifying the building’s acoustical weaknesses and vulnerabilities, then devised a workable solution to meet the producers’ schedule.
They advised lining the building’s eight colossal doors, (large enough to have once accommodated ships) with Acoustiblok® 1660 3mm, a superior sound isolation material with an average noise reduction of 26 decibels (dB). Acoustiblok, which has
also been installed at both Pinewood and Leavesden studios in the UK, was installed by the filmmakers under the close supervision of the Acoustiblok team.
Vast cavities within each door were first filled with an open cell fibre. Acoustiblok membrane was then attached to steel supports within the doors and secured with resilient channels. The steel structure was also treated with Thermablok® aerogel insulation material to increase acoustical dampening, and to address transmission loss properties. New corrugated facing panels were installed as an external finish.
Brian Martin, a technician with Muldiss Darton Productions of the UK, said that producers were hard pressed to find a workable solution to the noise problemnoise problem that could be in place before scheduled filming began.
“This new project represents the biggest film yet for the Paint Hall studios, and we needed the best possible sound abatement material installed in a very short period of time,” Martin said. “It’s crucial that we have perfect sound conditions for filming and
recording, as the microphones used are highly sensitive and can pick up every single sound in the background.
“Acoustiblok responded quickly to our deadlines, and their sound isolation material worked exceptionally well, especially considering the large scale of this facility.”
Acoustiblok is made of a 1/8” (3 mm) thick proprietary viscoelastic polymer material with a high-density mineral content, heavy yet extremely flexible. While other manufacturers of sound proofing materials attempt to stop or absorb sound, Acoustiblok has resolved the problem in a vastly different way.
Through a unique thermodynamic process, Acoustiblok is engineered to transform sound energy into inaudible friction energy as the material flexes from sound waves.
One thin layer of Acoustiblok in a standard metal or wood stud wall will result in more sound reduction, and provide more privacy, than 12” (30.5 cm) of poured concrete.
Acoustiblok backs its claims with hard science and certified independent laboratory test results. The acoustical laboratory at Architectural Testing, Inc. in York, Pennsylvania, recorded an astounding Sound Transmission Class (STC) of 85 for a concrete block and metal stud wall design configuration that included Acoustiblok, a noise reduction of 99-percent to human hearing.
Ultimately, the installation of Acoustiblok to the Paint Hall studios has made it an extremely desirable venue for attracting future big budget films.
Paint Hall is not the first major film studio to install Acoustiblok for perfect sound quality. The UK’s Pinewood and Leavesden studios are also treated with Acoustiblok, setting the stage for some major blockbusters including the Harry Potter, Star Wars, and James Bond movies.

Building or retrofitting a kennel can present some unique challenges for dog-loving entrepreneurs, but if engineered properly a kennel can and should be an affordable, quiet, and neighbor-friendly facility.
When Deb and Jon B. hired contractors to design and build their 28 x 60-foot dog kennel in rural Iowa back in 2003, their decades-long dream of housing and caring for their farm community’s canines quickly turned nightmarish when one neighbor complained that the noise from the barking was affecting his health.
The neighbor insisted that the noise of the dogs barking was loud enough to not only interfere with his sleep, but with his quality of life during the day as well, and indeed the noise level did exceed the county’s EPA sound level limits (as do most kennels.)
The couple learned about Acoustiblok only after a series of legal headaches and illadvised fixes like custom built “sound-blocking” panels and custom-made “husher” acoustical curtains did nothing to appease the neighbor’s complaints. Despite each new fix, the police got involved, and soon the courts became involved.
By 2005, contractors hired by the couple had sealed windows and completely enclosed the dog run in order to address the noise problem.
“It took away the dogs’ visibility, and completely changed the look of the building,” Deb said. “It began to look like a jail, and still it did not significantly reduce the noise level.”
With legal and construction costs piling up, Deb came very close to closing shop and returning to her previous work as an insurance adjuster. In April 2009, the couple held a farm sale to raise money for their legal expenses;
The situation had become bleak, until a local lumberyard operator suggested she look into Acoustiblok. Deb decided to give the Tampa, Florida-based company a call. That phone call changed everything.
“I had a significant business at stake,” she said. “I was beside myself when I made the call to Acoustiblok; this conflict had ripped our lives apart.
“How I wish I knew then what I have learned now from the people at Acoustiblok.”
The UL approved Acoustiblok material is a unique soundproofing material which has taken years to develop. Just one thin, 1/8-inch layer of Acoustiblok in a standard stud wall can reduce more sound than 12-inches of concrete. The soft flexible material is 4.5 feet wide and is available in 30, 60, or 350-foot rolls.
Acoustiblok is usually stapled or screwed to studs before drywalling. It is a fire rated proprietary formula, heavy mineral filled, viscoelastic polymer which is easily cut with a utility knife.
While other materials attempt to block or absorb sound, Acoustiblok does neither. As the heavy, limp Acoustiblok material vibrates from the sound, it actually transforms the acoustical energy into inaudible friction energy in a process sometimes referred to as "isothermal adiabatic".
Lead, previously considered the best soundproofing, works on precisely the same basis
and has exactly the same sound transmission classification (STC) rating.
Steve Hibbens, an Acoustiblok acoustical consultant, spoke with Deb at length regarding her kennel and helped her formulate a game plan for addressing her architectural challenges and utilizing Acoustiblok to her best advantage. Before installation began,
Acoustiblok consultants held a conference call with the couple’s contractor to advise on the installation process for maximum benefit.
“It’s not just about using our material, but also applying sound abatement construction techniques that work together with Acoustiblok for maximum sound reduction,” Hibbens said.
Contractor Dave Hanson removed the kennel’s aluminum siding and took the kennel down to the metal studs. Installation took about 18 hours, as Hanson and one employee installed Acoustiblok one segment at a time so that the dogs did not have to be displaced in the process.
Eco-friendly Acoustiblok is safe for the dogs and kennel personnel; it contains no lead, barium, or asbestos, is UV resistant, impervious to water and mold, and is UL fire rated
and classified for wall, floor and ceiling installations as well as industrial applications.
In addition to Acoustiblok, Hanson replaced the existing windows with triple pane, low RE windows for a combined effect so impressive, he said he will recommend Acoustiblok in future construction and retrofitting projects. “If sound is a problem, this is the product to use,” Hanson said.
Deb was impressed as well. In fact, she is so convinced that the guidance of Acoustiblok experts and the effectiveness of the product itself has made such a profound impact on the quality of her life, she has become something of an acoustical expert in her own right. Her next project includes adding Acoustiblok ceiling tiles in the kennel, and hanging strategically placed Acoustifence on the property for complete sound abatement.
As her business flourishes, she sees the improvements as an affordable and effective investment in the future.
“I have learned so much from your company,” Deb said. “Acoustiblok has saved our lifestyle, saved our kennel, and allowed us to continue doing what we waited our whole lives to do.”

HOBOKEN, New Jersey – Residents of the Lexington apartments in Hoboken enjoy more than the usual amenities that are part and parcel in most upscale residences: tranquility.
When construction was completed on the upscale, 49-unit Lexington in 2008, it wasn’t the granite countertops, the stainless appliances or even the hardwood floors that set a new standard in quality living for its residents. In fact, it’s what they can’t see – or hear – that makes their living spaces exceptional.
Acoustiblok® sound abatement material installed under the drywall and subfloor during construction of the Lexington provides an environment that is void of the ambient noise often associated with apartment living. Lexington tenants won’t hear their neighbor’s TV, conversations or clamor to get out the door in the morning. What they will hear is the silence that quality noise abatement material installed beneath the visible surfaces of their
Having Acoustiblok as a feature is a boost to Realtor Basil Skaltsis, who finds tenants for the Lexington. Skaltsis says that most high-end apartment seekers expect a high level of privacy, and since tenants tend to speak up only when there’s a problem, the lack of complaints about noise speaks volumes.
“No one has made any noise complaints ever since the building opened,” Skaltsis says. “But you have to keep in mind that maybe they don’t think about noise because they don’t have it.
“Until you’ve lived below someone whose child has a Big Wheel, or next door to someone whose radio can be heard in your own space, you’re probably not going to worry about noise abatement. In this particular building, no one mentions sound abatement because it’s something they don’t have to think about.”
UL approved Acoustiblok is a unique soundproofing material that took years to develop. Just one thin 1/8-inch layer of Acoustiblok in a standard stud wall and on top of subflooring can reduce more sound than 12-inches of concrete. The soft flexible material is
4.5-feet wide and is available in 30, 60, or 350-foot rolls.
Acoustiblok is usually stapled or screwed to studs before dry walling. It is a proprietary formula, heavy mineral filled, viscoelastic polymer that is easily cut with a utility knife. While other materials attempt to " block" or "absorb" sound the heavy, limp Acoustiblok material vibrates from the sound, actually transforming the acoustical energy into inaudible friction energy in a process sometimes referred to as "isothermal adiabatic.” Lead, previously considered the best soundproofing, works on precisely the same basis and has exactly the same STC rating. Unlike lead, Acoustiblok is eco-friendly, moisture and mold resistant, and contains no harmful pollutants.
Set in the heart of the tony Columbus Park area of Hoboken, each apartment in the Lexington offers an oasis from the hustle and bustle of the city while allowing its residents the convenience and perks that come with living in a cosmopolitan setting. The brand name of choice for quality acoustical aesthetics, Acoustiblok is available worldwide, is easily installed and will last the life of the building. Install it once, and enjoy the quiet for a lifetime. For more information, visit our website at www.acoustiblok.com, e-mail us at email@example.com, or call us at 813-980.1400.

TAMPA, Florida – Public awareness of the health risks of industry-related noise pollution has never been higher. Industrial plants worldwide are incorporating serious sound abatement strategies into their infrastructure to protect employees and visitors from hearing loss and other medical issues raised by industrial noise pollution.
Supervisors at the South Broward Waste to Energy (WTE) plant in Fort Lauderdale, Florida, were faced with a 30-day project to overhaul the plant’s turbine. The plant’s steam bypass system would take over the turbine’s 24-hours a day waste management responsibilities for one full month.
The problem with the transition was the unbearable blare of the bypass system. The bypass channels 900 pounds per square inch of compressed steam through a 14-inch pipe into a 7-foot diameter pipe at a noise level of 126-dB. This is an unsafe level equilevent to jackhammer or jet engine launch.
The noise was so deafening that even with earplugs, employees and visiting contractors could not spend more than brief periods of time in the vicinity without risking hearing damage. Verbal communication was impossible, even if they shouted, while working on or around the system.
The decision to install Acoustiblok® sound abatement material to the bypass system was made after Acoustiblok’s Shawn Saathoff, president/director of Acoustiblok Middle East, evaluated the site and proposed a blanket application of Acoustiblok’s 1/8-inch thick
proprietary viscoelastic polymer with a Sound Transmission Classification (STC) of 26, unmatched in its versatility. Since the bypass system is composed of pipes elevated more than five stories, Acoustiblok’s ease of installation, flexibility, effectiveness, and environmentally friendly properties and made it ideal for the job.
The South Broward WTE facility is owned by Wheelabrator Technologies, an OSHA recognized and award-winning clean energy facilitator. With plants across the United States, Wheelabrator prides itself on its commitment to environmental responsibility. This makes Wheelabrator a natural match for eco-friendly Acoustiblok. The sound proofing material contains no lead, barium, or asbestos. It is UV resistant, impervious to water and mold. Acoustiblok is UL fire rated and classified for wall, floor and ceiling installations as well as industrial applications.
However, while solving the sound abatement issues, a new problem arose. The heat emitted from the compressed steam travelling through the bypass system reaches temperatures as high as 350-degrees. Yet Acoustiblok’s standard application range is 200-degrees before its viscosity is challenged.
After conferring with Thermablok® Sales Professional Steve Hibbens, South Broward WTE Maintenance Manager Paul Benton chose to gird the system with a 5-mm layer of Thermablok insulating material before applying the Acoustiblok.
Thermablok adapts aerogel technology developed by NASA to create the highest insulating material in existence. Composed almost completely of air, aerogel is known as "liquid smoke." Previously, aerogel had been difficult to adapt to most uses because of its fragility. Thermablok overcomes this by using a unique patented fiber to suspend a proprietary formula of aerogel so that it can be bent or compressed while still retaining its amazing insulation properties.
Although this type of project had never been attempted before, both teams gambled successfully on the results of scientific studies performed on both Thermablok and Acoustiblok to determine the best solution to thwart the offending noise and deal with the associated heat issue.
Benton said that the need for noise abatement at the plant had been brewing for some time before the turbine overhaul created the incentive he needed to take action.
One contractor found the extreme, unrelenting howl of the bypass system so difficult to work with, he began to dramatically hike the cost for his crews to work on site.
“Not only had it become a health issue, it had become a financial issue as well,” Benton said. ”Contractors were going to charge more to work here, and employees would have to severely reduce their hours to minimize exposure to the noise.”
The massive pipes were enveloped first in 1,280 square feet of Thermablok High Temp, then in 1,575 square feet of Acoustiblok by a four-man crew from Coastal Insulation in Pompano Beach, FL. Steve Sill, vice president of Coastal Insulation, said the job, which took three weeks to complete, was imposing only because of the sheer size of the system.
“It was challenging in that we were working off lifts higher than five stories,” he said. “But we were surprised how easy the material was to install, and how well it worked.
“We couldn’t believe the difference,” Sill said after the application of Acoustiblok was complete. “We measured a 26-28 dB attenuation, which was significant enough that contractors could actually hold a conversation while standing next to the structure,
whereas before you couldn’t be heard if you screamed.
“This success became even more amazing when the plant manager told us that the factory was running at nearly 50% greater capacity than when the original readings were taken.”
For crews to work under such conditions is actually painful at such a noise level, and studies confirm the adverse health effects of industrial noise pollution on workers in such an environment. Benton, too, was amazed at the results of the black Acoustiblok material seamed with black and yellow Acoustigrip permanent bonding tape, which far surpassed his expectations.
“We wouldn’t have cared if it was magenta with white polka dots, we would use it again, we were so happy with the results,” Benton said.
Acoustiblok is made of a 1/8” (3 mm) thick proprietary viscoelastic polymer material with a high-density mineral content, heavy yet extremely flexible. While other manufacturers of sound proofing materials attempt to stop or absorb sound, Acoustiblok has resolved the problem in a vastly different way:
Through a unique thermodynamic process, Acoustiblok is engineered to transform sound energy into inaudible friction energy as the material flexes from sound waves. One thin layer of Acoustiblok in a standard metal or wood stud wall results in more sound reduction - and provide more privacy - than 12” (30.5 cm) of poured concrete.
