I’m Not Hearing! What Could it Be?

Posted by Living Sounds

Even a mild hearing loss can affect our day-to-day. Untreated, hearing loss can result in withdrawal from social situations, irritability, self-criticism, impaired memory, depression, fatigue, less alertness to the environment and reduced overall psychological health.   You should have your hearing checked once a year, or immediately if you or your loved ones notice changes in your hearing and understanding. 

Different kinds of hearing loss:

Sensorineural Hearing Loss

  • Occurs when there is damage to the cochlea (inner ear) or to the nerve pathways from the cochlea to the brain.
  • Generally cannot be surgically or medically corrected.
  • Most common type of permanent hearing loss.
  • Reduces the ability to hear faint sound, resulting in speech being unclear or sounding muffled.

Possible Causes for Sensorineural Hearing Loss

  • Age – known as Presbycusis or nerve damage. This is a very gradual, even unnoticeable loss. It usually occurs in the higher frequency range vital to understanding speech.
  • Noise Damage- Exposure to firearms, industrial or home machinery and loud musical concerts. Can be caused by even a single incident. Prolong exposure to loud noise can cause permanent hearing loss.
  • Disease/Trauma- Meniere’s Disease (which may also be accompanied by vertigo, nausea and tinnitus), tumours, birth injury, skull fractures and some viral infections.
  • Medication-Large doses of aspirin, some forms of antibiotics, diuretics and chemotherapy can cause hearing loss.
  • Genetic or hereditary- hearing loss can run in your family.

Conductive Hearing Loss

  • Occurs when conditions interfere with the conduction of sound through the outer, middle or inner ear.
  • Usually involves a reduction in sound level or the ability to hear faint sounds.
  • May be treatable medically or surgically.

Possible Causes for Conductive Hearing Loss

  • Fluid in the middle ear from colds or allergy
  • Ear infections
  • Poor Eustachian tube function
  • Perforated Tympanic membrane (eardrum)
  • Benign tumours
  • Impacted cerumen (earwax)
  • External otitis (infection of the ear canal)
  • Otitis ecxterna (swimmer’s ear)
  • Presence of a foreign body in the canal
  • Absence or malformation of the outer ear, ear canal or middle ear

Mixed Hearing Loss

  • Sometimes occurs in combination with a sensorineural hearing loss. In other words, there may be damage in the outer or middle ear and in the inner ear (cochlea) or auditory nerve.
