NOISE SURVEY MARINE DOCK itl INTAKE PUMPS/NEW CONTROL ROOM BLDG.
The attached noise survey was made using a B & K Sound Level Meter Model 2219. A previous survey was made before the new control room building was erected and these results also were below the OSHA standard of 85 decibels (dBA).
The new control room building interior noise levels are well below the OSHA standard.
All survey results are shown in decibels (dBA).
