National Research Agenda for the Prevention of Occupational Hearing Loss

Occupational hearing loss is the most common work-related injury in the United States. Although the estimates vary, it is thought that ~22 million U.S. workers are exposed to hazardous noise levels at work, and an additional 9 million are exposed to ototoxic chemicals, which also can lead to hearing impairment. A significant but unknown number of workers have suffered a work-related hearing loss. The problem crosses many occupational sectors, including manufacturing, construction, transportation, agriculture, and the military. Hearing loss resulting from noise or chemical exposures is permanent. It is also preventable. In addition to hearing loss, many workers suffer from noise-induced tinnitus (ringing in the ears) and face the possibility of noise-related accidents and other adverse health effects.
