Exposure Monitoring & Control Surveys |
Pacific
EH&S professionals conduct sound level surveys and noise exposure
monitoring in varying occupational and community
environments. Such surveys are performed using noise
monitoring equipment that includes audio dosimeters and/or sound
level meters. The dosimeters allow us to record employee
8-hour time-weighted average exposures to noise in connection with
specific operations for comparison to applicable exposure
guidelines, and sound level meters provide useful information such
as peak sound level values associated with specific operations. Upon
completion of a noise survey, a comprehensive report is prepared
that includes background information; observations of specific
work activities and operations, and environmental conditions; a
description of the monitoring methodology; a discussion of the
results in light of applicable regulations (i.e. OSHA exposure
guidelines); conclusions; and where appropriate, recommendations
pertaining to issues such as engineering controls (i.e. shielding,
equipment maintenance and/or modification, and damping), personal
protective equipment, employee training, and hearing conservation
programs. With published absorption coefficient data, our
engineers also have the capability to calculate Room Constant
values which can then be used in determining the feasibility of
acoustic treatments.
