Acoustiblok Fence Quiets Noise for Neighbors Near Hillsborough County, Fla Wastewater Treatment Plant

An Acoustiblok Acoustifence was used to help quiet noise coming from a 200-HP Carrousel vertical, high efficiency aerator drive motor at the Hillsborough County Northwest Regional Water Reclamation Facility

TAMPA, Fla (PRWEB) January 16, 2013

(PRWEB) January 11, 2012 – An Acoustiblok noise barrier recently installed near a noisy exposed aerator motor at the Hillsborough County Northwest Regional Water Reclamation Facility resulted in an immediate and significant reduction in noise pollution for neighboring residents according to the Acoustiblok Corporation, the manufacturer and developer of Acoustifence.        

The facility is part of a 1,500-acre multi-use tract owned by Hillsborough County. It is a Type 1 advanced wastewater treatment facility built to process five million gallons of wastewater per day. The facility is located on a 67-acre parcel of land 10890 South Mobley Road in Hillsborough County Florida. A residential community called Highland Park is located near the county facility.

Last year, members of the Highland Park Residential Community voiced their complaints about loud whining noises coming into their community from the nearby county facility. The facility took action to find a solution to the noise issue. In residential areas, road traffic noise is usually the major source of noise, with air conditioning/heat pumps, generators, construction, and industrial noises also problems typically.

The wastewater treatment facility noise source was a 200-HP Carrousel vertical, high efficiency aerator drive motor located on top of the facility's 24-foot Oxidation Aeration Basin structure according to Flint Seth, general manager of bio solids production and maintenance at the Hillsborough County Northwest Water Reclamation Facility.

Doug Fisher of the Hillsborough County Public Utilities Department worked with Acoustiblok to devise an economical solution consisting of an L-shaped frame barrier with four 6 X 30 foot-Acoustifence outdoor noise reduction panels secured to it. Acoustifence is a product of Acoustiblok Corporation. Witt Fence Company of Riverview, Fla., was contacted by Hillsborough County personnel to install the barrier.

From a technical standpoint, Acoustifence is an advanced sound barrier. A sound barrier, by its own named definition, is put between the noise source and the listener. Some barriers can be made of virtually anything that sound does not penetrate. There are however, differences and distinct advantages in some over others. Unlike a concrete block wall, which in one respect is a good sound barrier, the Acoustifence actually flexes with certain frequencies, especially very low frequencies. In the process of sound waves physically moving it, the product transforms sound wave energy into inaudible internal friction energy. A concrete block wall would not do this. As the Acoustifence is only 1/8 of an inch thick, it is very easy to position it closer to the noise source. The closer a barrier is to the noise source the more restricting it becomes to the initial sound waves.

Acoustiblok Corporation's Acoustifence product is a unique proprietary formula. It is a heavy mineral filled viscoelastic polymer material that is 1/8 inch thick and made in the United States. It comes in 6 X 30 foot-sheets. It is one of the most effective first steps in reducing noise for many applications including industrial, commercial, and residential. The amount of noise it reduces however is much related to other reflective structures in the area.

A noise meter was used to measure the difference in sound before and after the installation of the noise barrier fence at the wastewater facility. Typical noise from these Carrousel vertical aerator motors ranges from 80-83 decibels from three feet away according to the manufacturer. From 10 feet away, the noise measured 79 decibels before installation of the Acoustifence began and registered 69 decibels immediately after the fence was in place. In a 10 decibel decrease in sound level, perceived loudness is cut in half to the human ear.

“While we were pleased with the reduction in sound decibels picked up by the meter, the most significant difference that we noticed was the reduction in noise heard by the ear. The reduction in noise felt significantly higher than what registered on the sound meter,” said Seth.

Besides the proven and tested sound reduction qualities of Acoustifence, another beneficial quality of the product is that it is quick and easy to install. “Once we determine the technical solution to a noise issue, the installation of our products is not time consuming or labor intensive,” said Lahnie Johnson, President and Founder of Acoustiblok.

Installation of the sound barrier at the Hillsborough County facility was fast and they encountered no unexpected problems. “It took only one day to install the barrier and it resulted in an immediate decrease in directional noise for our facility,” Seth said.

“Acoustiblok's success is not just about the products we have invented but more about the innovation of the products in finding solutions for people's noise problems. For advanced problems, we incorporate state-of-the-art acoustical prediction software modeling. This allows us to really tie down what the results will be in advance of someone's purchase and of course can result in huge financial savings to the customer,” Johnson added.

While the solution to the noise issue at the wastewater treatment facility was not a complex one, it was an effective one for Hillsborough County. “The Acoustifence barrier made a difference and we are very pleased with it. We have not received any new complaints about the motor noise since the installation of the barrier fence so that's a good sign so far. We are currently planning to build additional barrier fences for some of the other vertical aerator motors we have on site,” Seth added.

While Hillsborough County is happy with how the small amount of Acoustifence quieted the large pump, Johnson sees this as the first of literally thousands of similar pumps around the country and overseas that may need a similar noise abatement solution.
