About the NHCA:
The mission of the NHCA is to prevent hearing loss due to noise and other environmental factors in all sectors of society.
NHCA was formed in June of 1976, at that time designated as the Hearing Conservation Association, and incorporated in the state of Florida on July 8, 1976. The organization changed its name to the National Hearing Conservation Association in 1981. The founders of NHCA were mainly audiologists and otolaryngologists who were concerned with the serious problem of noise-induced hearing impairment resulting from occupational exposure to noise. The Association was created to provide a forum where others of similar persuasion could share information and gain increased insights regarding occupational hearing conservation.
