Noise level data were gathered for U.S. Army Corps of Engineers CE powerhouses including most of the larger powerhouses, in order to determine 1 the nature and extent of excessive noise levels in excess of hearing conservation criteria in CE powerhouses and 2 which noise sources were common to most CE powerhouses. The results indicate numerous areas in CE powerhouses where noise levels are excessive. The general noise sources are the turbines, the generators, and various auxiliary pumps, such as fish pumps or air conditioning chiller pumps. This investigation also determined that the 120 Hz pure tone radiated by the main electrical generators at CE powerhouses may constitute more of a hazard than current hearing conservation standards indicate.
