A Certified Occupational Hearing Conservationist plays a key role in any hearing conservation team. By attending our Occupational Hearing Conservation course you can become a certified Occupational Hearing Conservationist (OHC). The course consists of lectures, practical and written examinations, and “hands-on” practical workshop sessions including hearing testing, equipment calibration checks, otoscopic screenings, and hearing protection fitting. This training complies with OSHA, MSHA and FRA requirements for personnel conducting audiometric testing for Hearing Conservation Programs in industry, mining and railroad. We cover all relevant “current best practices” for managing hearing conservation programs.
