Proctor & Gamble do Brazil

SCOPE OF WORK

The Louveira Manufacturing Plant produces a diversity of personal care and beauty products, including diapers and shampoo. The plant is located outside the town of Louveira in Sao Paulo State, but close to a small village.

To assist Proctor & Gamble in responding to noise complaints from residents of a nearby village located just outside the town of Louveira, and to successfully meet legal requirements, INNOVA was contracted to undertake three separate activities:

  • Implement two acoustical surveys
  • Design preliminary noise mitigation solutions
  • Provide budget pricing 

ACOUSTICAL REQUIREMENTS

The plant is located near a small village outside of the town of Louveira and is in close proximity to a motel, located approximately 545 feet (166 meters) away. The legal compliance level of 50 dBA was chosen as the target at the site of the motel.

NOISE SOURCES

Through acoustical surveys, INNOVA identified a variety of noise sources, including nine process fans, six air compressors, four cooling towers and the building's ventilation system.

SILENCING SOLUTIONS

The INNOVA team designed, supplied and installed its proprietary acoustical assemblies for the walls, roof, acoustical doors, silencers and barrier walls.

RESULTS

INNOVA completed the work within a four month period.
