Welcome to NHCA!

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 professionals with similar interests could share information and gain increased insights regarding occupational hearing conservation.

  • Audiologists
  • Engineers
  • Industrial hygienists
  • Safety professionals
  • Physicians
  • Nurses
  • Others

At the bottom line, however, NHCA is a group of passionate hearing conservationists willing to share their expertise in the quest for the prevention of hearing loss.
