TAMPA, Fla., December 11, 2013 – Acoustiblok’s All Weather Sound Panel noise barriers installed under the premium seating section of the new east side grandstand at Illinois State University’s $27.6 million renovated football stadium diminishes loud compressor noise and gives fans a better game day experience.

All Weather Sound Panels are industrial grade acoustical barrier assemblies used to block excessive noise in industrial, commercial, institutional and community environments. These unique noise barrier panels are not just “sound absorbing” but also “sound blocking.” This allows them to not only absorb the loud mechanical noise, but also stop noise from penetrating through the panel.

The renovation of Hancock Stadium was needed to replace the outdated structures in the stadium that had been the home to Illinois State University since the early 1960s. The stadium lacked modern amenities and premium seating and entertainment areas that are common in today’s modern college football stadiums. These premium areas are vital to bringing in additional revenue for the university.

The renovation focused on the stadium’s east side area which was rebuilt and transformed into the stadium’s new modern 7-story front entrance and premium seating area. The new east side structure now includes a 5,500 sq. ft. indoor club, seven private luxury boxes, catering area, more modern and expanded concession areas and restrooms, bleacher back seating areas, and a state-of-the art press box among other improvements. The improvements have doubled the seating capacity of Hancock Stadium and have created a stadium that the community can now be proud of.

These new indoor areas require ventilation, cooling, heating and also refrigeration for concession and entertainment areas which require the use of noisy compressors. These machines typically result in a combination of two noise sources: noise that was already there in the signal, now amplified; and noise created by the actual circuit design and components of the compressor. Compressors often draw complaints for loud humming, rumbling, scraping, thumping and vibrating, rattling, squealing, or pop and bang sounds.

At Hancock Stadium and most stadiums in general, the noisy compressors and other mechanical equipment are located under the concourse level which typically pose a noise problem if not properly addressed with an acoustical barrier like Acoustiblok’s All Weather Sound Panels. These panels are available in various sizes up to 4 x 12 foot, are approximately 2.44-inches thick with aluminum frame and have a perforated aluminum grille. They are all welded, with tubular enforced eyelets in the frame allowing use of anchors or tapcons for wall mounting. All Weather Sound Panels contain the company’s signature product, Acoustiblok sound mitigating material which is a 1/8-inch thick heavy mineral-filled viscoelastic material which stops sound from penetrating through it. This is a very meaningful advantage over conventional "sound absorbing" panels which stop sound reflections but are poor sound barriers.

All Weather Sound Panels are rigid and self-supporting. They can be used like building blocks to permanently or temporarily enclose a noise source such as chillers, generators, and other machinery. The product widely is used in industrial and commercial facilities where loud, ongoing noise is a concern.

David Vance is senior vice president of Associated Constructors, a Bloomington, Illinois multi-trade subcontracting construction company that performed the interior finishing work for the Hancock Stadium renovation project. The company has been in existence for 29 years.

2013 05 16 08 17 14“We installed two sections of Acoustiblok’s All Weather Sound panels in areas that were approximately 16 X 70 feet. The panels were suspended with unistrut metal framing system and 3/8 inch threaded cable rod on the same slope on the bottom of the bleachers,” said Vance.

“It was the first time we used these All Weather Sound Panels and they worked out great. The architect liked them too."

“Acoustiblok did a great job packaging and crating the sound panels. We were impressed with this. The panels arrived in great shape and we had no problems handling them. It took us a day to determine how we were going to construct and fasten the barrier under the sloped area. We undid the seating bracing and threaded them through the L cuts we made. Once we had the installation sequence down, we had no problems.”

HANCOCK Stadium BEST photo original Marilyn Myers is Chief Operating Officer of Acoustiblok. She coordinated the sale and planning of the All Weather Sound Panels for the projects.

“Each noise problem we solve at Acoustiblok has its own unique set of design challenges. There are a lot of design factors to consider when you are trying to mitigate noise in a specific environment. Modern day sports stadiums are unique in that there are both indoor and outdoor areas interconnected. The challenge was to create a sound barrier that mitigated unwanted chiller and machinery noise and keep it isolated so it does not negatively impact the fans sitting above. They accomplished this using our All Weather Sound Panels,” said Myers.

“Hancock Stadium shows us that Acoustiblok’s All Weather Sound Panels are effective for use in modern day sports stadiums that have chiller and HVAC system noise,” she added.

We got toward the end of the installation and the width was changed and we needed a few custom sized panels unexpectedly. Acoustiblok made them for us quickly and shipped them to us right away. We appreciated their responsiveness and concern for our needs and deadline,” Vance added.

Acoustiblok’s All Weather Sound Panels use only the highest quality material and craftsmanship. Strain hardened 0.040" (1.016mm) corrosion resistant perforated aluminum front is resistant to abuse and sharp objects. The heavy duty frames have 18 flush eyelets free from any protrusions or screw heads thus allowing flush stacking and storage.

Acoustiblok manufactures two versions of these indoor /outdoor sound panels available: one with hurricane-rated internal reinforcement and one without. They are easily movable and do not need to be permanent as they can be stored in harsh environments without harm from the elements.

“The panels were priced right. It’s a good product. We would definitely use the product again,” Vance concluded.

Lahnie Johnson is president and founder of Acoustiblok. “We’re very proud of our All Weather Sound Panels and we think it’s a great product. There are many indoor and outdoor uses for these panels,” Johnson said.

While 2013 ushered in a whole new era of Redbirds football for Illinois State University at the bigger and more modern Hancock Stadium, Acoustiblok’s All Weather Sound Panels are working quietly without fanfare to keep mechanical noise to a minimum.

Chiller Noise No Longer Problem After Acoustifence Barrier Installed

Posted by Liz Ernst on Mon, Apr 30, 2012 @ 05:56 PM

(L) A 24 foot tall, three sided Acoustifence barrier was installed around the industrial chiller on an existing chain link fence. (R) The top 10 feet of the adjacent Festival Foods warehouse-sized store is treated with QuietFiber to prevent sound reflection over the top of the chiller barrier.

SHEBOYGEN, Wisconsin, April 30, 2012 – Installation of a 24-foot noise barrier utilizing Acoustifence outdoor sound abatement material at the new Sheboygan Festival Foods store is complete, ending complaints from nearby residents over extreme levels of noise leaking from the store’s industrial refrigeration chillers into the community.

Folks in Sheboygen were celebrating when the popular Wisconsin-based Festival Foods grocery chain opened the 70,000 square foot mega store here on September 16, 2011. Less than two weeks later, the community’s warm welcome had grown icy as neighbors began to complain about noise from the store’s industrial refrigeration chiller that was so loud, it violated the city’s noise ordinance.  

Festival Foods enlisted the help of Acoustical Engineer Eric Wolfram of Milwaukee-based Scott R. Riedel & Associates, LTD, who consulted with Acoustiblok’s Jay Boland to choose Acoustifence noise barrier material, a product of Acoustiblok, Inc. of Tampa Florida, to bring the decibel level down below the legal threshold and restore peace and quiet to the neighboring community.

When Wolfram first investigated the site in September, decibel readings ranged between 78.4 and 90.7, loud enough to be a risk for noise-related health problems to nearby residents and workers, had they been subjected to the noise over time. The Sheboygan Department of City Development demanded the level be reduced by at least five decibels, Wolfram said.

“The existing refrigeration pump and motor systems produce extreme noise levels,” Wolfram said. “This noise reverberates within the sheet-metal paneled enclosure interior and escapes through several different exhaust and ventilation openings.

“Additional noise was generated by the cooling and exhaust fans mounted above the enclosure.”

Working with sound consultants from Acoustiblok, Inc., Wolfram designed a two-step solution, creating a barrier with Acoustifence noise deadening material to block noise around the massive system, and incorporating another Acoustiblok product, QuietFiber, to help reduce sound from reflecting off of the taller adjacent building behind the chillers.

Minimal structural changes were required, as the ⅛- inch Acoustifence was easily attached to an existing chain link fence and the outdoor-rated QuietFiber with a perforated metal cover was capconed to the building.

The results were better than Wolfram had hoped, with decibel levels reduced to 57.3 the moment the barrier was in place – well below the City’s legal threshold, and more than 20 decibels lower than before the Acoustiblok products were installed. Neighbors are no longer bombarded with the irritating chiller noise, now replaced with the ordinary ambient sounds that existed before.

Sounds from local traffic and roadways exceeded that of the compressor equipment after installation of the Acoustifence and QuietFiber products,” Wolfram said.

Lahnie Johnson, founder and president of Acoustiblok, Inc., applauded Festival Foods’ quick action in addressing the noise complaints right away, stating that the product combination was the perfect solution for this particular type of noise challenge.

“The Acoustifence and QuietFIber treatments were the perfect solution for the Festival Foods chiller noise, as both of these materials are designed to hold up in inclement weather, and as you can see from the results, they do their job well beyond everyone’s expectations,” Johnson said. “The Acoustifence and Quiet Fiber are also substantially less costly than attempting a structural enclosure solution.”

Blue Ridge Regional Jail Installs Acoustifence to Quiet Chillers

Posted by Liz Ernst on Thu, Apr 28, 2011 @ 11:01 AM

Blue Ridge Regional Jail quieter with the use of Acoustical FenceAcoustic Fence known as Acoustifence - made in U.S.A.

LYNCHBURG, Virginia, April 27, 2011– Rolling green hills and pastoral settings are a top draw for residents and visitors to Lynchburg, Virginia. When noise from two aging 125-ton chillers at the Blue Ridge Regional Jail in downtown Lynchburg began disturbing neighbors in the hillside community outside the downtown area, jail officials wasted no time finding a solution that would return the peace and quiet its neighbors had always enjoyed.

Once the complaints began coming in -- not from the facility’s immediate neighbors, but from residents on the hillsides surrounding the jail -- Blue Ridge Regional Jail Authority officials had to determine whether the chillers' noise levels were within local ordinances and regulations governing noise, and found that they were in compliance. 

“We were below acceptable noise levels, but we wanted to do the right thing and find a solution that would restore quiet to the neighbors and meet our budget and installation needs,” said Kenneth Floyd, maintenance director at the jail.

Floyd said he searched online for a noise abatement solution and came across the Acoustiblok website; one product, Acoustifence, met the facility’s needs.

Acoustiblok Chief Operating Officer Marilyn Myers worked with Floyd in determining the best solution for quieting the jail’s chiller noise.  Acoustiblok provides indoor and outdoor noise deadening products for a myriad of applications; Myers determined that the easy-to- install Acoustifence material would offer the best all-around sound abatement for this application.

“It’s working very well,” Floyd said. “We installed it around the chillers, and I was surprised at how easy it was to install because it is heavy.

“But we haven’t had a single complaint since it went up.”

The reciprocating chillers, which have been in place since the jail was built in 1998, are air-cooled. Noise emanating into critical areas -- screw compressors (on the bottom of the unit) generate mid/hi frequency noise, up-blast fans (on the top) generate low frequency noise. This is one type of industrial noise pollution that experts warn can be hazardous to the health of individuals subjected to it on an ongoing basis.

World Fence News defines Acoustifence as a "new defense against outdoor noise pollution." Commonly employed in industrial usage, small and private airports, construction sites, mass transit rail lines and even dog kennels, it is also available for residential use.

The Acoustifence is a unique 1/8th-inch thick heavy mineral filled viscoelastic acoustical material available in a standard 6-foot x 30-foot (3mm x 1.83m x 9.14m), although longer lengths and taller heights are available.  To suit their needs, jail officials ordered 90 feet of 9-foot tall Acoustifence to wrap around their chillers. Unlike fences or shrubs, Acoustifence performs well at blocking direct sound while reducing reflective sound at the same time. 

With acoustical properties that provide a lab-certified STC (sound transmission classification) of 28 dB, a reduction that represents a sound decrease of 85-percent to the human ear, Acoustifence also reduces sound that can reflect over or around the fence and reverberate off surrounding objects, creating a secondary noise problem.

This is not the first time a jail has utilized Acoustiblok sound abatement material to resolve a noise problem; in 2010, a Pinellas County, Florida jail installed Acoustiblok "All Weather Sound Panels" to resolve a noise problem caused by sound reverberations and echo in the jail's concrete videoconferencing room. 

"Every noise issue we're faced with calls for a solution that addresses a host of unique variables," said Lahnie Johnson, president and founder of Acoustiblok, Inc.

"We offer a variety of noise reduction products, and the expertise to determine the best approach to resolve every problem."
