82 • FEBRUARY 2013 • WORLD FENCE NEWS Acoustifence reduces noise from water treatment plant continued from page 80 it can cause permanent damage after only one work day (8 hours). 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. Johnson continued: 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. 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. According to OSHA, typical engine noise, mainly caused by mechanical and combustion forces, can typically range from 100 – 121 decibels measured at approximately 10 feet. 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 con- suming or labor intensive," stated Johnson. "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," Johnson added. "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." 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.
