There are four types of hearing loss:

  • Conductive: caused by obstructions or diseases in the outer or middle ear that usually affect all frequencies of hearing.
  • Sensorineural: results from damage to the inner ear. The loss ranges from mild to profound and affects certain frequencies more than others.
  • Mixed: occurs in both the inner- and the outer or middle ear.
  • Central: results from damage to the central nervous system

Hearing loss ranges from mild to profound. The distinctions between the terminology of “hard of hearing”, “deaf”, “deafened” are based on the individual’s preferred language (spoken or sign) rather than the degree of hearing loss. Hard of hearing or deafened individuals may use hearing aids, cochlear implants or other assistive listening devices.
