SANTA MONICA, CALIF., May 21, 2013 – A towering and stout zig zag-shaped construction fence that spans nearly 800 feet long and is lined with Acoustiblok, Inc.’s Acoustifence soundproofing material at the Santa Monica High School (SAMOHI) Science & Technology Building Project has helped reduce construction noise for students and the local community by 10 decibels each day over the past two years. A 10 decibel decrease in sound level cuts perceived loudness to the human ear in half, making this black colored acoustic fence very “green.”

If all sections of this acoustical construction fence were linked together in a line, it would span nearly two and a half football fields and be as tall as a two to three story commercial building in some sections. Why is this much fencing needed? This three year, $55 million improvement project entails reconfiguring a 5.2-acre northern portion of the existing 26-acre school campus. The school is located in a densely populated area of posh Santa Monica near businesses and residential dwellings.

An existing softball field was demolished and a new modern 97,000 square-foot science and technology building is being built in its place. Once completed, the old science and technology building will be demolished and a new softball field will be built in its place. The Acoustifence construction barrier will moved and reused to mitigate noise escaping to the nearby neighborhoods during various phases of the project. Additional outdoor site improvements are being constructed as well on the SAMOHI campus. The construction project began in December 2011 and is scheduled to be completed in winter 2014. It is approximately 48 percent complete at the time of the writing of this news article. More information about the project can be found at: http://fip.smmusd.org/santamonica.html

Acoustifence is a modern day acoustical soundproofing product developed by Tampa, Fla.-based Acoustiblok, Inc. It’s an advanced material sound barrier that is placed between a noise source and the noise receiver. The Acoustifence material easily attaches to chain link fences and comes in large sections and in custom made sizes, making it ideal for construction fence applications that require a soundproofing element at the construction site. Acoustifence material is extremely strong and was engineered to withstand harsh outdoor environments like construction sites and highway environments. Full exposure to dirt, grease, oil, mold or even being driven over is not a problem for the Acoustifence.

The word “green” refers to environmentally-preferable attributes of a product, service, and/or technology. The 1/8” thick Acoustifence is a unique proprietary formula. It is a heavy mineral filled viscoelastic polymer material that is made in the United States from all USA made material. Acoustifence is 100 percent made in the United States. It does not contain lead, asbestos, or barium and is UV-resistant and impervious to water and mold. Graffiti, a real consideration in a school area, is easily removed compared to other surfaces. Acoustifence has had proven success in many demanding applications and is an effective defense against outdoor noise pollution.

A construction project this large isn’t simple or easy. It’s messy, noisy and can disturb the usual flow for people around the construction site. The school district was committed to minimizing disruption to students, staff and nearby neighbors during the construction. Mitigating construction noise and dust going into the school and neighborhoods located directly across the street had to be addressed by project planners. The main high school building is located within very close proximity of the construction area. Single family homes, apartment complexes and businesses are located in areas across the street from the campus.

Project planners decided early on that acoustical barriers will be in place to reduce noise levels for classrooms and neighbors and that the construction area will be separated from the working campus by a safety fence and that

“This 5.2-acre construction site is very spread out. Controlling noise from heavy machines, demolition, and construction activities can be challenging at large construction sites located in densely populated areas,” said Glenn Nadalet, Senior Construction Manager for Parsons/CCM.

Two sides of the Acoustifence barrier are being used to protect the neighborhood and the other portion protects the school. Temporary chain link construction fencing is commonly used at construction sites to help prevent theft and damage to machinery, equipment, and property, as well as provide security for the construction crew.

The SAMOHI construction project Acoustifence ranges in height from 14-20 feet at different parts of the construction site and zigzags around the perimeter near the street and the existing school building. In addition to the construction fence, Acoustifence soundproofing material was draped over the side of the top portion of the school building to help make the second floor quieter for students during construction.

“Our heavy equipment machines emit between 90-100 decibels of noise while operating depending on the machine itself. Throughout the day, these machines are sometimes located 250-300 feet away from the school building making it virtually impossible to contain all the noise,” Nadalet said.

Heavy equipment machines are needed to build large buildings and rebuild a large area like at Santa Monica High School. According to the U.S. Environmental Protection Agency, noise from various construction machines can range from 70-95 decibels at 50 feet. One front loader can reach approximately 83 decibels; scrapers, graders and backhoes approximately 92 decibels; concrete mixers and cranes approximately 88 decibels, earth moving tractors can reach approximately 95 decibels. A single jackhammer can reach nearly 100 decibels and a pile driver reaches approximately 105 decibels. So a 10-decibel decrease in construction noise significantly helps to keep it within a more tolerable range.

Santa Monica AB Website Main photos for AB Website 4“The Acoustifence noise barrier wall is located about 10 feet from the school building so our machines are not always located within close proximity to the noise barrier fence. We work hard to keep construction noise as minimal as possible while moving the project forward to meet our deadlines,” Nadalet said.

Noise intensity is measured in decibel units. The decibel scale is logarithmic; each 10-decibel increase represents a tenfold increase in noise intensity. Human perception of loudness also conforms to a logarithmic scale; a 10-decibel increase is perceived as roughly a doubling of loudness and a 10-decibel decrease is perceived as half as loud. A typical conversation occurs at 60 decibels – not loud enough to cause damage. If a sound reaches 85 decibels or stronger, it can cause permanent damage to a person’s hearing with prolonged exposure. The amount of time a person listens to a sound affects how much damage it will cause.

“The Acoustifence is psychologically positive for the students, teachers and administrators at the school. It gives them confidence that we are taking care of their noise concerns. We believe we get about a 10 decibel decrease in construction-related noise for the neighbors and school with the Acoustifence barrier,” Nadalet said.

Acoustiblok now also produces beautiful landscape covers for its fences. Since the covers are an actual photograph of different scenery, such as foliage, flowers, brick, or stones, it is virtually indistinguishable and many say better than real life.

Marilyn Myers is Acoustiblok’s Chief Operating Officer who worked on the Santa Monica Fence project. “All our noise barrier products are affected by where they are positioned in reference to the noise source, the distance between the noise source and the noise receiver, the height of the barrier, and the type of environment they are in. The amount of noise Acoustifence reduces is also much related to other reflective structures in the area,” she said.

The Public Works Division of FenceCorp, a leading California fencing company based in Riverside, Calif., won the bid to install the large temporary acoustic fence for the project. Acoustiblok’s Acoustifence material was considered to be the best choice for its proven performance and ease of installation.

Ira Schechtel, Manager of FenceCorp’s Temporary Rental Fence Division at the Oceanside, Calif. Branch, helped oversee the work. He was heavily involved in the bidding and administrative aspects of the project. Schechtel is an experienced fence professional with 30 years experience in the fence industry. He is also the former president of the California Chapter of the American Fence Association.

“Because the cost and human effort associated with the acoustical fence is higher than a typical chain link fence, it was important that we not make mistakes when we built it. We have to do things right the first time to avoid costly mistakes with these types of fences. A mistake on an acoustical fence is much more substantial in terms of dollars per section than typical chain link fences.”

A fence of this magnitude would be a significant financial loss if it failed to adequately reduce noise. To ensure results, Acoustiblok Corporation’s engineering department uses acoustical outdoor modeling software to accurately predict the acoustical results in advance. The software, called Cadna A, was developed in Germany to create cities with reduced noise levels and is considered the most advanced of its kind.

Schechtel and vice presidents Perry Massie and Alan Kay, and Superintendent Kenny Kocek helped oversee the bidding and installation of the Santa Monica Construction Fence project. “The bidding and installation process for a large specialized fence like this takes more time and effort than people may think. Due to the height of the barrier walls, we engineered the large posts and cables to specifically hold the dense and flexible acoustical fence. Even the barriers on the existing building were specifically designed for Acoustifence. It truly takes a team effort to do these things right and be successful in the fencing business.”

“As we do more Acoustifence projects, we are learning what to look for in advance. Each Acoustifence project has its own unique set of environmental, noise and design challenges with our customers. This is not a one size fits all fencing application. There’s more science to them and to be effective, they have to be positioned in the right places around the noise sources. This just adds to our capabilities,” Schechtel added.

Acoustifence is an effective soundproofing solution because it’s a thin outdoor noise blocking material which acoustically performs precisely as lead does, but without the environmental hazard of lead said Myers. Acoustifence comes in 6 X 30 foot sections considered the most effective first step in reducing noise. It’s now being widely used in construction and building environments, at industrial facilities to quiet generator and motor noises, for mass transit rail lines, residential, and in many other outdoor applications where noise has been an unresolved problem she said.

Lahnie Johnson is President and founder of Acoustiblok, Inc. He drives new product development at Acoustiblok. “Acoustical soundproofing materials and products like Acoustifence, Acoustiblok material, Quietfiber, and our indoor and outdoor All Weather Sound Panels compete in specialized niche markets,” he said.

“People are becoming more aware of noise problems and the stress it causes them. Santa Monica High School is just one example. With greater population density and increasing noise pollution and noise control regulations being passed by local, state and federal governments, the soundproofing products and services market is continually on the rise and we’re here to help meet their needs.”

All Weather Sound Panels® Resolve Generator Noise at LDS Temple

Posted by Liz Ernst on Wed, Oct 31, 2012 @ 11:55 AM

AWS Panels at LDS Temple AWS Panels LDS Temple LDSPanels7

VANCOUVER, BC, October 22, 2012 – Raicor Contracting, Ltd. earned the Northwest Wall & Ceiling Bureau’s Outstanding Project of the Year 2012 award for the visually spectacular LDS Temple located about 50 miles southeast of Vancouver in Langley, BC.  Included in the project’s flawless design are Acoustiblok’s All Weather Sound Panels, custom fit to create a clean, architecturally attractive noise barrier for the Temple’s roofless ancillary building that houses an industrial generator and HVAC systems.

Project Manager Timo Orava of Raicor worked with acoustic specialist Steve Hibbens, who recommended the All Weather Sound Panels for the project. Not only did the Temple officials want the noise reduced for Church members to worship in peace and quiet, the solution had to offer a clean, architecturally attractive appearance in keeping with the meticulously designed interior.

The LDS Temple which was built in the spirit of Solomon’s Temple of the Old Testament, according to Orava. Extreme care was taken not only in the design, but in the execution, which took more than three years to complete.

“The LDS Temple is an inspiring monument that Church leaders wanted built to perfection, right down to the very last detail,” Orava says. “It’s a visually stunning structure built to last, ideally, for hundreds of years.

“Church leaders’ interest was in getting a completed structure that is pleasing to God’s eye, and nothing less would suffice.”

The project was challenging for Orava’s team at Raicor because of the extremely high building standards in place, and the Temple leaders’ meticulous requirements. With a zero-tolerance for deficiencies, from the drywall to the wall sconces, the project demanded faultless workmanship. Orava said the Acoustiblok All Weather Sound Panels were no exception, and needed to fit exacting specifications in the structure.

“One-eighth of an inch off anywhere, and they would not have fit,” he said. “But the Acoustiblok team custom cut and finished each panel to the exact dimensions, and they all fit together flawlessly.”

Nineteen standard 4 foot x 8 foot panels and 13 custom sized panels were used to create the precision noise barrier that Temple leaders wanted; clean, aesthetically pleasing, and most important, effective.

“After the panels went in, the noise issue was resolved, which was surprising because the building that houses this noisy industrial equipment has no roof,” Orava says. “The noise is no longer a problem.”

Acoustiblok President and Founder Lahnie Johnson says the All Weather Sound Panels  are different from other conventional sound panels. In addition to being able to stand up to the most extreme environments, they not only absorb virtually all sound but they also contain a layer of Acoustiblok material which provides exceptional noise blockage.

The sound absorbency of the panel brings down substantially the acoustical energy around the generator and chiller by eliminating all sound reflections in the area, while the Acoustiblok material in the panel allows it to also be an excellent sound barrier. These qualities make the All Weather Sound Panels a perfect fit for the LDS Temple, where they will perform at their full potential in the Northwest Canadian environment.

“Vancouver experiences some real weather extremes, which these panels are built for,” Johnson says.

“In addition, when they are worked into an architectural design with this kind of precision and attention to detail, they offer an enhanced aesthetic when appearance is important, as it was here.”

About Acoustiblok All Weather Sound Panels®:

Acoustiblok, a NASA “Spin-off” company, developed the All Weather Sound Panels, engineered specifically to withstand the most rigorous outdoor and industrial environments. Water, moisture, humid salt air or salt water, dirt, dust, UV, chlorine air, corrosion, and most harsh chemicals do not affect them. The industrial sound panels are available with an acoustically transparent five micron stainless steel dust filter for outdoor use in the world’s toughest environments, from the mining industry to the desert areas of the Middle East, and other applications where dust is a concern. Acoustiblok sound panels are extremely durable and are currently in use by the United States Army in the Middle East.

Washable, durable, long lasting and usable in hundreds of areas and applications, the Acoustiblok All Weather Sound Panels are not just "sound absorbing" but also "sound blocking." This allows the panel to not only absorb sound but also stop the sound from penetrating through the panel, a very meaningful advantage over conventional "sound absorbing" panels that stop sound reflections but are poor sound barriers.  

With an unprecedented noise reduction coefficient (NRC) of 1.00 (Riverbank Acoustical Laboratories test results), they are the only noise barrier wind-load tested to 270 mph. Rigid and self-supporting, they can be used like building blocks to permanently or temporarily enclose any noise source, such as chillers and industrial machinery.

Distribution Facility Noise Resolved with Acoustifence Noise Barrier

Posted by Liz Ernst on Wed, May 30, 2012 @ 03:47 PM

AIBONITO, Puerto Rico, May 23, 2012 – Installation of an 18-foot noise barrier utilizing Acoustifence sound blocking material has resolved a noise problem caused by truck traffic to and from the To-Ricos, Ltd. chicken processing and distribution facility in Albonito, Puerto Rico.

A common problem at industrial plants across the U.S. and Puerto Rico, trucks at the To-Ricos facility arrive day and night to be loaded and unloaded, and are often left idling for hours. The loud noise created by the trucks bled into the neighboring residential community, and unable to escape it whether they were indoors or outdoors, neighbors began to complain. Exposure to continuous industrial noise can cause sleeplessness, elevated blood pressure, depression and other health problems.

To-Ricos officials took action by contacting Tampa, Florida-based Acoustiblok, Inc., a manufacturer of residential and industrial noise abatement solutions. Acoustiblok consultants recommended the 18-foot Acoustifence barrier to block the truck noise from escaping into the neighboring community without interfering with the trucks’ ability to perform their functions and keep the plant operational.

Acoustifence is a thin outdoor noise blocking material which acoustically performs precisely as lead does, but without the environmental hazard of lead. It is now widely used in industrial environments, highways, construction sites, mass transit rail lines and in many other outdoor applications where noise is a problem.

Plant personnel constructed an 18 foot metal frame to support the Acoustifence sections, which was easily attached thanks to anodized brass eyelets installed along the top and bottom edge of each section, using heavy duty nylon ties included with the product.

“Acoustifence is becoming more popular for industrial applications like this one, where truck and traffic noise is bleeding into the surrounding communities and literally disrupting people’s lives,” said Lahnie Johnson, founder and president of Acoustiblok, Inc.

“To-Ricos has proven itself to be a good neighbor by addressing the noise problem as soon as they became aware of it, allowing us to help them design and fulfill a noise barrier solution that works and can last for years in their tropical island environment.”

 

To-Ricos is a division of the Pilgrim’s Corporation, the world’s second largest chicken producer headquartered in Greeley, Colorado.

About Acoustifence:  

Acoustiblok, Inc., a NASA spin-off company, has been providing high quality noise abatement products since 1998, earning the industry’s highest ratings from architects, builders, consumers, and even the British House of Commons. Acoustifence is a 1/8-inch (3mm) thick unique sound deadening material measuring 6 feet (1.82 meters) high by 30-feet (9.14 meters) long with black anodized brass eyelets along the top and bottom edge for easy attachment to any existing fence or structure.

Heavy-duty nylon ties are included with each roll. Easily installed or removed in less than one hour, impervious to mold, mildew, and UV, Acoustifence is virtually indestructible. The soundproofing material in Acoustifence is a proprietary formula of the Acoustiblok Corporation, developed and refined over a 10-year period.

Acoustifence has proven performance and is easily suspended from a chain link fence, eliminating the need for expensive permitting or structural requirements. Any height can be obtained by simply overlapping the sections. To store, Acoustifence sections simply roll up like carpet into less than a 12-inch diameter. Independent lab tests of the U.S.-made Acoustifence material show a sound transmission classification (STC) of 28, which represents to the human ear an approximately 85-percent sound reduction. However, results will be less, relative to surrounding sound reflective objects such as buildings or trees and the amount of Acoustifence installed.

Acoustiblok, Inc. also has available high quality landscape attachments which fit directly over the Acoustifence to provide a realistic landscape appearance. A variety of landscape attachments are available to choose from, including floral gardens, green meadows, English garden walls, and other scenic illustrations to blend into any natural backdrop or enhance an unfinished yard or property.

Acoustifence® Installed at Coca-Cola Plant Cuts Industrial Noise

Posted by Liz Ernst on Thu, Jan 12, 2012 @ 01:55 PM

After installation of Acoustifence, decibel readings at the Coca Cola plant dropped from 89 to 68 decibels (left); and at the adjacent residence, dropped to 42.9 decibels (right)

BAY CITY, Michigan, January 12, 2012 – Coca-Cola has completed installation of Acoustifence® noise barrier fencing along the west perimeter of its Bay City plant, bringing to an abrupt halt those noise issues that had been plaguing neighbors in the surrounding community and attracting local news organizations as the outcry from area residents grew.

Architect Jack Zelazny of Dearborn, Michigan, acting as a consultant to Coca Cola’s contractor Kirco Manix, chose Acoustifence noise barrier fencing for the core of the 300-foot wide noise barrier project designed to alleviate noise from idling delivery trucks at the plant that had been plaguing neighbors in the South End Community.

Zelazny said the initial plan was to construct a 30-foot acoustical metal fence along the perimeter roadway to address the problem, but he nixed the idea in favor of something significantly less expensive and more aesthetically pleasing and to the community’s residents.

“I didn’t think it was appropriate for the neighbors to have to stare at a 30-foot industrial metal fence from their small residential yards,” Zelazny said. “I really wanted to find something more organic and natural.”

After researching sound barrier fencing options, he found Acoustifence, a product of Acoustiblok, Inc. in Tampa Florida, and discussed his options with acoustical consultant Paul Getts of Acoustiblok.  After conferring with Getts, Zelazny moved ahead with construction of a grass covered, 300-foot wide berm that incorporated a nine foot high Acoustifence barrier and landscaping for an attractive roadside aesthetic. The project was completed in the final weeks of December, and both company officials and neighbors rang in the New Year with their new found peace and quiet.

“The Acoustifence went up flawlessly, and it’s not unpleasant to look at,” Zelazny said. “When we covered it with the dark green acoustical fabric covering, it looked natural and organic, as we had hoped.

“But the real surprise was the immediate impact it had on the noise.”

Zelazny said the plant noise measured at 89 decibels before installation of the Acoustifence began, and registered at 68 decibels immediately after the Acoustifence went up. His hope was to lower the noise by 20 decibels, a figure that was exceeded at the plant, and more than doubled at the neighboring residence as soon as the Acoustifence was put in place. A reading taken at the adjacent residential property registered in the low to mid 40 decibel range.  

“It exceeded my expectations, I think it exceeded everyone’s expectations,” he said. “The people at Coca Cola are happy with it, and most importantly the neighbors in the surrounding community are happy with it.

“I couldn’t speak more highly of it.”

Lahnie Johnson, president and founder of Acoustiblok, Inc., said that the application of Acoustifence in the bottling plant’s noise barrier berm was the soft drink company’s best alternative for significantly reducing noise, and respecting the surrounding community’s call for peace and quiet.

“I think Coca Cola acted quickly and responded to the area’s residents as a good corporate neighbor should,” Johnson said. “It’s particularly important that they sought out a serious noise blocking option while respecting the fact that neighboring residents 

would be living with whatever solution they chose, and viewing it every day – some from their own back yards.”

Acoustifence was designed to address outdoor noise pollution in residential communities, or any community that cares about its appearance.”

Acoustiblok Products Quiet Generator in DIY Soundproofing Project

Posted by Liz Ernst on Tue, Aug 2, 2011 @ 02:44 PM

Acoustifence and QuietFiber are combined in a weekend DIY soundproofing project for a Maryland homeowner looking to quiet his backyard emergency generator.

Generator noise barrier sound deadening  Emergency generator noise sounddeadening sound barrier  sound barrier HVAC noise  Outdoor generator noise barrier sound deadening

ROCKVILLE, Maryland, August 1, 2011 --  Maryland resident John Rachlin spent one weekend in July building and installing a noise deadening barrier around his home emergency generator unit using Acoustiblok sound reduction materials, a DIY project intended to bring the generator’s noise levels down to local compliance levels, while sparing his neighbors from the unit’s high decibel screech when in use.

Rachlin, an investment banker and self-proclaimed “slightly handy” do-it-yourselfer purchased the emergency generator to insure power during Montgomery County’s notorious power outages that can last anywhere from a few hours to a few days.

After moving into his newly built house in a densely populated subdivision, Rachlin decided that installing the generator was a necessity, but the noise levels from the brand new unit were registering much higher than the manufacturer’s estimate.

Using a decibel reader, Rachlin measured normal levels, without the generator on, at 50-decibels (which included ambient noise from neighbors’ HVAC units and other normal background sounds), and between 78- and 80-decibels with the generator running.

“I decided to do something about soundproofing the unit before the neighbors had a chance to complain,” Rachlin said. “I wanted to create a low-sound environment for my neighbors and my family.

“I also was concerned that the generator was exceeding Montgomery County’s fairly strict noise ordinances.”

Rachlin began by building an enclosure using pressure treated lumber that matched his property’s perimeter fence to maintain the nicely appointed atmosphere of his yard and patio area. Once built, he lined the enclosure first with (1/8-inch) Acoustiblok noise deadening material, and topped it with QuietFiber noise absorbing material. Rachlin said he had researched soundproofing options extensively before singling out Acoustiblok over three other similar companies. (Acoustiblok’s website lists actual independent lab test results on its noise abatement products.)

With installation guidance provided by Paul Getts, a sound consultant with Acoustiblok, Inc., Rachlin was able to attach the Acoustiblok to the wood surface using small screws with ½-inch washers to, which provided the sound blocking measure he needed. He followed up by attaching QuietFiber on top of the Acoustiblok to add a level of noise absorption to the project.

“It took three days and many gallons of water to keep me hydrated, because we’ve had record heat levels up here this summer,” Rachlin said. “But I was able to complete the entire project myself in one weekend, which made my wife very happy.”

Rachlin measured the results of the enclosure after the soundproofing application was complete, and said the result was a noise reduction of more than 10-decibels, which translated to more than 50-percent reduction in perceived sound. Since the unit needs to remain open on one side to prevent obstruction to the air-cooled engine, which he accomplished with ventilating latticework at the base of the enclosure, Rachlin attached QuietFiber to the inside of the generator’s  top lid and front panel, resulting in an additional four- to five-decibel reduction.

“Montgomery County has an infrastructure that dates back to the 1930’s and is all above ground,” Rachlin said. “We are extremely susceptible to power outages, and have lost one too many freezers filled with meat, and spent more than enough hot Maryland summer days with no air conditioning when the power went out.

“When we built this house, we knew that we had to have a generator in place. The final step was making it quiet enough to be good neighbors, keep the noise ordinance officials happy, and enjoy having power when we need it.”

Generator noise is a growing problem everywhere, especially in residential neighborhoods, where multiple units can be running at once after a storm or power outage,” said Lahnie Johnson, founder and president of Acoustiblok, Inc. “This is the type of noise that contributes to noise pollution and the health risks that go along with it. People are becoming more proactive about creating a quiet environment, especially at home.

“Mr. Rachlin’s project represents just one of the ingenious ways ordinary homeowners can take on a soundproofing project themselves and make it into a satisfying DIY weekend project. We are proud of our innovative noise deadening products that people can work with to achieve soundproofing at home without the need to hire contractors or installation experts.”

Acoustiblok sound reduction material is made of a 1/8-inch (3 mm) thick proprietary viscoelastic polymer material with a high-density, non-barium mineral content, heavy yet extremely flexible. It is easily cut to fit with a box cutter, which makes it customizable to fit around pipes and other fixtures. Just one thin layer of Acoustiblok added to a standard metal or wood stud wall will result in more sound reduction - and provide more privacy - than 12-inches (30.5 cm) of poured concrete.

Unlike fiberglass, QuietFiber is not only UV tolerant, but also totally hydrophobic (will not absorb water or moisture), and specifically designed for maximum (NRC 1.00) noise absorption. In addition, it will not support mold or mildew, and can work in temperatures above 1800-degrees. QuietFiber is UL fire rated for floor, wall and ceiling applications, and like all Acoustiblok products, 100-percent recyclable and 100-percent made in the U.S.

Acoustifence Provides Noise Reduction for Outdoor Restaurant Music

Posted by Liz Ernst on Wed, Jun 22, 2011 @ 03:50 PM

Sound emanating from an outdoor stage at a popular Jupiter, Florida restaurant was creating problems for neighbors and challenging local noise ordinances until Acoustifence noise barrier was installed to keep the peace without sacrificing the restaurant’s live music offerings.

JUPITER, Florida, June 20, 2011 – The tropical, waterfront setting of Guanabanas restaurant on Florida’s southeast coast invites guests to pull up and dock their boat or arrive by more traditional means, and settle in for a meal, a drink, and most nights, live music. But the acoustics were causing a problem in paradise, as sound from the live music, amplified by the stage’s proximity to the water, was rising to decibel levels above Palm Beach County ordinance limits.

Guanabana’s Sound Engineer Matt Cahur worked with Paul Getts, an acoustical consultant at Acoustiblok, Inc. in Tampa, to determine the best approach for reducing noise from the outdoor stage during live performances without detracting from the restaurant’s extravagant tropical setting complete with tiki huts and a large customized chickee hut bar, giving the property a definitive Caribbean flavor.

Guanabana’s utilizes a wide variety of Florida’s lush tropical vegetation and woods for all of its décor. The stage, tables, chairs, fencing and all wooden structures are made of Florida pine and bamboo.

The property itself is generously landscaped with palms, ferns, bromeliads, gladiolus and a variety of additional native flora.

The challenge was to find an effective sound barrier that would meet, or even surpass local noise ordinance limits without interfering with the meticulously designed property.

“We’ve tried a lot of different sound abatement solutions to stop the noise bleed from our property during the live performances, but nothing worked,” Cahur said.

“We have been searching for the right product that will not only address the sound issue, which is exacerbated because of the sound reflecting off the water, but one that we can conceal within the décor.

“Acoustifence met every single requirement, from a technical, structural, sound, and design perspective.”

Cahur said the Acoustifence material was easily hung on top of the property’s existing fence, and then concealed with the restaurant’s trademark tropical landscaping, resulting in a sound barrier that is completely undetectable to restaurant guests. Acoustifence was also hung on the stage door and walls, and concealed with natural wood planks and other thematic décor.

Since the Acoustifence was installed, Cahur says the live music is in full gear, and the neighbors are no longer left to deal with the loud music emanating from the stage.

“We haven’t gotten a single call since we put the Acoustifence in,” Cahur said.

Lahnie Johnson, founder and president of Acoustiblok, Inc., said the application of Acoustifence at Guanabana’s was the perfect combination of sound abatement material and architectural landscaping that can make an outdoor entertainment venue possible almost anywhere.

“We designed Acoustifence to install easily, so that it can be used as a temporary or permanent noise barrier,” Johnson said. “The ultimate use of Acoustifence is to conceal it under vegetation or in a garden setting, which gives the illusion that the vegetation is providing the privacy and noise reduction, which is exactly what Guanabana’s has done with excellent results.

“Since vegetation alone does nothing to reduce sound, concealing Acoustifence under the vegetation to act as a noise barrier is the perfect solution, any way you look at it.”

ABOUT ACOUSTIFENCE:

A 1/8-inch (3mm) thick unique sound deadening material measuring 6-feet (1.82 meters) high by 30-feet (9.14 meters) long with black anodized brass eyelets along the top and bottom edge for easy attachment.  Heavy-duty nylon ties are included with each roll. Easily installed or removed in less than one hour, impervious to mold, mildew, and UV, Acoustifence is virtually indestructible. The soundproofing material in Acoustifence is a proprietary formula of the Acoustiblok Corporation, developed and refined over a 10-year period.

Acoustiblok, Inc. now has available high quality landscape attachments which fit directly over the Acoustifence to provide a realistic landscape appearance. A variety of landscape attachments are available to choose from, including floral gardens, green meadows, English garden walls, and other scenic illustrations to blend into any natural backdrop or enhance an unfinished yard or property.  Acoustiblok is recognized and sold worldwide, earning product awards from the British House of Commons, as well as being one of NASA’s Top 49 Spinoff companies.

Acoustifence has proven performance in highway environments, construction sites, and waste-to-energy plants, and can accommodate any height fence or structure by simply overlapping the sections. To store, Acoustifence sections simply roll up like carpet into less than a 12-inch diameter. Independent lab tests of the Acoustifence material show a sound transmission classification (STC) of 28, which represents to the human ear an approximately 85-percent reduction in sound. However, results will be less, relative to surrounding sound reflective objects such as buildings or trees and the amount of Acoustifence installed.

Acoustifence® Brings Peace and Quiet Back to Seattle Residents

Posted by Liz Ernst on Tue, Nov 2, 2010 @ 05:09 PM

SEATTLE, Washington – November 2, 2010 -- When the Link light rail system first began running in July 2009, Rainier Valley and Tukwilla residents in south Seattle were unprepared for the screeching, tearing and grating sounds that began filling their air space 20 hours per day, seven days a week.

Sound Transit Authority’s Justin Garrod, project manager for the Link rail system was called upon to find a solution to the high noise level that exceeded federal standards in south Seattle and dramatically interfered with the area residents’ quality of life. After doing the research and trying other methods, Gerrod and his staff discovered Acoustifence, which is comprised of a unique sound deadening material - a perfect temporary fix, Gerrod thought, until a permanent solution could be found.

After simply hanging the Acoustifence from 5,000 feet of guardrail flanking the actual rail tracks, Gerrod quickly realized he had found a permanent solution.

“We’re convinced this is it, this is the answer to the noise problem,” Garrod said. “Acoustifence met all the criteria, it’s cost effective, easy to maintain and an excellent sound deadening material.”

Additionally, installation was easy as the Acoustifence is easily cut to size for a custom fit and attached with supplied industrial strength nylon ties connecting the material to the existing guardrail.

“We combined the Acoustifence material with rail grinding (another noise reduction measure) and the combined results were exactly what we needed,” Garrod said.

When Sound Transit was originally designing the Link light rail system, noise levels were predicted by examining studies on the noise output of other similar light rail transit systems in other cities.

Based on the expected noise levels, mitigation features were designed into the original project. These features included sound-insulating some of the homes along Martin Luther King Jr. Way S. in south Seattle and constructing noise walls in Tukwila. Still, the noise deadening measures taken did not work for all areas of Tukwila, with some still exceeding federal standards. (Solid barrier walls do little to mitigate rail noise. Solid walls reflect the noise back at the rail car, which in turn reflects the noise back over the top of the wall.)

Steve Hibbens, rail noise consultant for Acoustiblok, the company that manufactures and distributes Acoustifence, said the solution worked so well, Sound Transit Authority plans to order more of the patented noise abatement material to keep in stock. Hibbens is also working with Atlanta’s rail system, MARTA, implementing Acoustiblok All Weather Sound Panels to absorb rail noise.

“Sound Transit Authority is really happy with the results,” Hibbens said. “There have been several write-ups about the project success in Seattle area papers.

“The neighbors are happy too.”
