One contractor found the extreme, unrelenting howl of the bypass system so difficult to work with, he began to dramatically hike the cost for his crews to work on site. "Not only had it become a health issue, it had become a financial issue as well," Benton said. "Contractors were going to charge more to work here, and employees would have to severely reduce their hours to minimize exposure to the noise."
For crews to work under such conditions is actually painful at such a noise level, and studies confirm the adverse health effects of industrial noise pollution on workers in such an environment.
The massive pipes were enveloped first in 1,280 square feet of Thermablok High Temp, then in 1,575 square feet of Acoustiblok by a four-man crew from Coastal Insulation in Pompano Beach, FL. Steve Sill, vice president of Coastal Insulation, said the job, which took three weeks to complete, was imposing only because of the sheer size of the system.
"It was challenging in that we were working off lifts higher than five stories," he said. "But we were surprised how easy the material was to install, and how well it worked.
"We couldn't believe the difference," Sill said after the application of Acoustiblok was complete. "We measured a 26-28 dB attenuation, which was significant enough that contractors could actually hold a conversation while standing next to the structure, whereas before you couldn't be heard if you screamed.
"This success became even more amazing when the plant manager told us that the factory was running at nearly 50% greater capacity than when the original readings were taken."
Benton, too, was amazed at the results of the black Acoustiblok material seamed with black and yellow Acoustigrip permanent bonding tape, which far surpassed his e
