Accurate hearing tests identify early signs of noise-related hearing loss, so that preventive measures can be taken. In order to protect against hearing loss on the job, audiometric technicians advise workers to wear protective equipment on their ears. Audiometric technicians also routinely test these workers for hearing loss by performing an audiogram.
Audiometric technicians may work in private health clinics, occupational health clinics, large companies and manufacturing plants. Mobile testing is also performed. Technicians can be hired as employees or contract out their services.
Many people, such as nurses, occupational health workers and hearing aid dispensers, may be trained as audiometric technicians. They would do the work as a part of their regular job.
