Presbycusis is gradual hearing loss in both ears that commonly occurs as people age. This form of gradual hearing loss can be mild, moderate, or severe. Presbycusis that leads to permanent hearing loss may be referred to as nerve deafness.

There are several causes of presbycusis including:

  • Gradual degeneration of the inner ear
  • Changes the bone structure of the ear, a condition called otosclerosis
  • Changes in the hearing nerve pathways in the ear leading to the brain
  • Repeated exposure to loud sounds, music, or equipment which can damage the fragile hair cells within the inner ear involved in hearing
  • Hereditary or genetic influences
