Acoustifence quiets construction site clamorAcoustifence is gaining recogni-

tion as an effective sound barrier for mitigating construction noise in com-munities where large construction projects are taking place.

Recently, two large scale con-struction projects in the Los Angeles/Santa Monica areas used Acoustifence to minimize construction noise.

With much new development go-ing on in these regions, often neigh-bors may feel like they are being en-croached upon by the effects of new construction activity and construc-tion related noise. Acoustiblok, Inc.’s sound barrier product, Acoustifence, has now helped Santa Monica resi-dents cope with construction noise at two large sites.

Since 2011, an Acoustifence con-struction fence has been successfully utilized at the $55 million Santa Mon-ica High School Science and Tech-nology Building project.

In addition, Acoustifence is also being utilized in the construction of the Expo Phase 2 Operations and Maintenance Fa-cility complex, part of the $1.5 billion 6.6 mile extension of the Expo Light Rail Line from the existing terminus at Culver City.

The site is lo-cated at Stewart Street and Exposi-tion Boulevard in the City of Santa Monica.

Santa Monica is a densely popu-lated area where multi-family and sin-gle-family homes are located adjacent to the property. The neighbors, which include the residential plus some sen-sitive commercial tenants, face the two short sides and one long side of the rectangular piece of property.

The O&M facility contractor in-stalled a standard 8-foot high chain link construction fence on the project’s three sides where neighbors reside. The company then wrapped 1,000 lineal feet of Acoustifence sound bar-rier onto the chain link fence. Acous-tifence is a modern day acoustical soundproofing product developed by Tampa, Fla.-based Acoustiblok, Inc. It is being recognized more and more as a way to mitigate construction noise at large-scale construction projects.

“Acoustifence is a unique 1/8th inch, 6’ x 30’ (3mm x 1.83m x 9.14m)

heavy mineral filled, barium free vis-coelastic acoustical material. It’s an advanced material sound barrier that is placed between a noise source and the noise receiver,” noted Marilyn Myers, Acoustiblok’s chief operating officer, who worked with the consul-tant on the sale of the Acoustifence material. The material easily attach-es to chain link fences and comes in large sections and in custom made sizes, making it well suited for con-struction fence applications that re-quire a soundproofing element at the construction site.

Acoustifence is extremely strong and was engineered to withstand harsh outdoor environments like con-struction sites and highway environ-ments. Full exposure to dirt, grease, oil, mold or even being driven over is

not a problem for the Acoustifence.

“The contrac-tor needed the ma-terial fast and we were able to get it to them immedi-ately. They were able to install it quickly and were pleased with the re-sults,” Myers said.

The contractor wrapped as much Acoustifence as they could on the chain link fence. This creates an ef-fective noise barri-er and helps keep the construction noise levels down as best as possible, given that the area

is not completely enclosed. In addition to being a sound bar-

rier, Acoustifence’s opacity and black color also provides a visual separa-tion for the construction project and the neighbors. It also helps reduce the amount of dust that would otherwise blow through a chain link construc-tion fence.

“When performing a large-scale construction project in certain areas of the United States, there are local noise and vibration ordinances that re-quire adherence. While construction contractors are not required to put up an acoustical construction fence un-less they exceed the allowable limits, often times they make the decision to install one before work commenc-es to keep noise at a minimum to the surrounding residential and business neighbors. They want them to have the best experience possible during

tance of utilizing Acoustifence sound barriers on large-scale construction projects where construction noise is a concern,” he said.
