Functional (Unit) Sound Absorbing Panels Reduce Noise Levels in Waste Water Treatment Facility

This paper describes how, in October 1995, rooms within the integrated wastewater and sludge treatment facilities were evaluated as to their noise problems. Based on these studies, the paper found that several rooms would need to be treated with Unit Sound Absorbing Panels. Acoustical treatment to achieve maximum noise reduction was calculated. Functional (unit) Sound Absorbing Panels were installed on the ceilings and walls of both rooms. Average noise level in the pump room was reduced to 85 dBA and in this blower room to 82 dBA bringing the rooms into OSHA compliance, and reducing reverberation to levels that did not interfere with communication between workers.
