Data collected in various work environments with similar noise sources indicate exposures below hazardous levels. WorkSafeBC has noise data from a BC Ferry data center in 1991 and from the central computer processing area of a large hospital in 1992 indicating exposure levels of 79 and 72 dBA, respectively. Data on mechanical switch rooms also indicate exposure levels well below the hazardous criterion (measured at 70 dBA). These measurements take into consideration noise from servers, network equipment, and air conditioning equipment.
