  Hearing Loss

Minor decreases in hearing are common after age 20.

Hearing problems usually come on gradually, and rarely end in complete deafness.  There are many causes of hearing loss. Hearing loss can be divided into two main categories:

  • Sensorineural – Sensorineural also called nerve loss or inner ear hearing loss is the most common type of hearing impairment. It stems from damage to the nerve endings in the inner ear or the nerves that transmit the message from the inner ear to the brain.
  • Conductive - Conductive hearing loss is the term used to describe a hearing loss caused by the interruption or reduction of sounds passage through the ear canal or middle ear space. For example, a perforated ear drum affects how well sound is received by the eardrum causing decreased hearing. Ear infections are also common causes of conductive hearing losses.
  • Perforation - Perforation of the ear drum is a tear or puncture of the ear drum.
  • Ear Infection - Otitus media with effusion is a middle ear infection with fluid. The fluid builds up in the middle ear reducing the mobility of the ear drum and middle ear bones. Reduced mobility results in a low frequency conductive hearing impairment. Below is a picture of a person’s eardrum who is suffering from otitus media with effusion. Note the fluid and air bubbles behind the eardrum.
