Types of Hearing Losses

Types of Hearing Losses

Conductive hearing loss

type-conductive

 

What’s wrong Causes Amount of hearing loss
Parts in the outer ear and/or middle ear (eardrum and 3 bones) don’t work properly
  • Middle ear infections
  • Head injury
  • Birth defects
  • Disease such as otosclerosis
  • Mild to moderate hearing loss
  • To experience what your child may be hearing, try blocking your ears to mimic a conductive hearing loss. Sounds from outside are softer, but your own voice may sound louder

Sensorineural hearing loss*

type-sensorineural (1)

What’s wrong Causes Amount of hearing loss
Parts in the inner ear (cochlea and hair cells) don’t work properly
  • Normal aging process
  • Too much loud noise
  • Heredity/genetics
  • Head injury
  • Certain medications (cause damage to inner-ear hair cells)
  • Mild to profound hearing loss
  • Your child may struggle to hear normal sounds, or complain that speech sounds soft or mumbled. In the most severe case (profound deafness) they may not hear anything at all

Neural hearing loss*

type-neural

Hearing nerve doesn’t work properly
  • Heredity / genetics
  • Head injury
  • Tumor
  • Mild to profound hearing loss
  • Sounds are not only softer, but may seem muffled or garbled; harder to separate one sound from another and interpret meaning of speech and sounds

Mixed hearing loss

type-mixed

What’s wrong Causes Amount of hearing loss
A combination of conductive and sensorineural hearing loss
  • Combination of conductive and sensory causes
  • Mild to profound hearing loss

Single Sided Deafness (SSD)

 

What’s wrong Causes Amount of hearing loss
Profound sensorineural hearing loss in one ear only. Normal hearing from the other ear
  • Too much loud noise
  • Heredity/genetics
  • Head injury
  • Your child will have difficulty hearing in noisy places and may have trouble determining where sound is coming from
