Types of Hearing Loss

11
Conductive Hearing Loss

• This hearing loss affects the passage of sound
  between the ear drum and the inner ear. Sound
  passes down the ear canal to the ear drum and
  through the middle ear, where the sound is
  transmitted across the middle ear by the three
  bones called the ossicles to the inner ear.

12
Causes of Conductive Hearing Loss

  ear may stop sound from reaching the ear drum.

  outer ear (otitis externa) or middle ear
  (otitis media).
• Glue ear (otitis media with effusion) -
  Inflammation in the middle ear with associated
  fluid filling the middle ear space around the
  ossicles. The fluid stops the ossicles and ear
  drum from moving effectively and stops sound from
  passing easily through to the inner ear.
• Ear surgery - May damage the ear drum or small
  bones in the middle ear stopping sound from
  passing easily through to the inner ear.

13
Sensorineural hearing Loss

• The Sensorineural hearing loss is also known as
  SNHL, and occurs when inner ear nerves are
  damaged and cannot properly transmit signals to
  the brain. Dieases and Infection is the cause of
