Definition:
   Sensorineural deafness is a hearing loss
    which is acquired from moderate to
    severe damage to the inner ear, auditory
    nerve, of the brain.
    ◦ The auditory nerve is a specific nerve that
      runs from the ear to the brain.

Symptoms:
There are many considerations for the symptoms
 of this particular deafness:
  ◦ Certain sounds may seem too loud
  ◦ Difficulty in following a conversation with two or
    more people talking
  ◦ Hard of hearing in noisy areas
  ◦ Men’s voices are easier to hear than women’s voices
  ◦ Some voices may seem unaudible
  ◦ Difficulty hearing if there is background noise
  ◦ Hard to tell “s” or “th” sounds from each other
  ◦ A feeling of being unbalanced/dizzy
  ◦ Ringing, buzzing, or soft roaring in the ears
Causes:
Tiny nerve endings/hair cells in the inner
  ear are responsible for changing sounds
  into electric signals, which are then
  interpreted by the brain.
 ◦ When theses endings/cells are damaged, only
   certain sounds/signals can be interpreted.
      Birth: only 400 genetic syndromes are known
      Prenatal infections: toxoplasmosis, rubella, and herpes
      Age-related: presbycusis
      Vascular or immune disease
      Infections: meningitis, mumps, scarlet fever, measles
      Injury or extensively straining noises
Treatment                   Prevention:
 Hearing aids           Don’t blare music
 Assistive listening     while listening
  devices                 through headphones.
 Cochlear implants      Wear earplugs while
                          being a loud
                          enviroment
