The Occupational Hearing Conservationist (OHC; also known as an industrial audiometric technician) can, with supervision, conduct the practice of hearing conservation including pure-tone air-conduction hearing testing and associated duties (related to knowledge gained as described in Section II below). The OHC is expected to be a key member of the Occupational Hearing Conservation Program Team. OHC skills are intended for the occupational setting and may not be applicable in nonoccupational practices.
