Types of Hearing loss

Sensorineural hearing loss happens when there is damage to the inner ear or to the nerves that travel from the ear to the brain. Sensorineural hearing loss is permanent and can make even loud noises sound quiet to the listener.

Characteristic signs of sensorineural hearing loss

A sensorineural hearing loss causes softer sounds to become difficult to hear or distinguish. It can also make differentiating between similar sounds like “she” and “fee” a challenge.

Causes of sensorineural hearing loss

  • Aging – Aging is a main cause of all types of hearing loss
  • Noise exposure – Sensorineural hearing loss can be caused by loud noise exposure, which can lead to damage in the inner ear
  • Genetic or hereditary conditions – Genetic sensorineural hearing loss may affect infants from birth or develop later in life
  • Illnesses and conditions – Sensorineural hearing loss can be caused by several health conditions including: meningitis, Ménière's disease, acoustic neuroma, multiple sclerosis, and malformation of the inner ear
  • Drugs and medication – Sensorineural hearing loss can be a side-effect of certain medications and cancer treatment
  • Head trauma – Head injuries can cause damage to the inner ear, which in turn causes sensorineural hearing loss
  • Congenital and birth-related hearing loss – Injections during pregnancy, complications during birth, premature birth, and hereditary predispositions can all cause sensorineural hearing loss in newborns

Treatment for sensorineural hearing loss

Although there is no cure for sensorineural hearing loss, and it cannot be treated surgically or medically, many people with sensorineural hearing loss can benefit from the use of hearing aids.


Conductive hearing loss occurs when the passage of sound is blocked in either the ear canal or in the middle ear. People with conductive hearing loss have sound levels reduced on their way to the cochlea in the inner ear.

Types of conductive hearing loss

There are several types of conductive hearing loss. Sometimes a conductive hearing loss can be corrected with hearing aids. If the organ of Corti in the cochlea is functioning normally, hearing aids can help transmit sound in the outer or middle ear. Other types of conductive hearing loss can be treated medically or surgically.

Characteristic signs of conductive hearing loss

People with conductive hearing loss will find soft sounds difficult to hear at all frequencies, both low and high.

Causes of conductive hearing loss:

Conductive hearing loss can be caused by the following:

  • Accumulation of ear wax
  • Otitis media – A middle ear infection
  • Cholesteatoma – A growth in the middle ear
  • Otosclerosis – An abnormal bone growth near the middle ear
