Types of Hearing Loss

Hearing loss may occur in any part of the ear, or when the auditory (hearing) system isn’t working normally.

Outer Ear

The outer part of the ear may comprise:

  • the space we look at our sides in our head Also known by the name of the pinna
  • the canal that runs through the ear.
  • The eardrum commonly called the tympanic or tympanic, splits the middle and outer ear.

Middle Ear

The middle ear consists of:

  • The eardrum
  • 3 tiny bones referred to as Ossicles transmit the motion that the eardrum makes to the inside of the ear.

Inner Ear

The ear’s inner portion comprises:

  • The organ is similar to the sound of a snail, which is dubbed the cochlea
  • semicircular canals that aid in the balance
  • of the nerves that connect the brain.

Auditory (ear) Nerve

A nerve sends signals via an ear canal to the brain.

Auditory (Hearing) System

The auditory pathway processes the sound signal once it travels from the auditory canal into the brain. The pathways within our brains form a part that can hear.

Four types of hearing loss:
  • Conductive Hearing Loss
  • The cause of hearing loss can be traced to something that prevents sound from getting to the middle or the outer ear. Hearing loss is typically treated with surgery or medication.
  • Sensorineural Hearing Loss
  • Hearing loss can indicate that there’s a problem in your inner ear’s function. also referred to by the name of hearing nerve performs.
  • Mixed Hearing Loss
  • Auditory Neuropathy Spectrum Disorder
  • Hearing loss happens when sounds travel through the ear in a normal manner however, because of damage to the ear’s inner ear, or the auditory nerve, the sound isn’t correctly arranged so that the brain can be capable of comprehending. For more information, visit this website: National Institute for Hearing and Deafness. External icon.
The severity of hearing loss ranges from mild to severe
  • Mild Hearing Loss
  • A person with a hearing impairment of moderate level could hear some speech sounds but the soft sounds are hard to discern.
  • Moderate Hearing Loss
  • Someone with hearing loss of moderate severity may hear very little when speaking at a normal speed.
  • Severe Hearing Loss
  • People with severe hearing loss are able to hear speech when someone speaks at a normal rate and hears only loud sounds.
  • Profound Hearing Loss
  • A person with severe hearing loss cannot hear speech but can hear only hear very loud sounds.
The expression “hearing loss” can be described as
  • Unilateral or Bilateral
  • Hearing loss is only experienced in one hearing loss in one ear (unilateral) or both hearing loss occurs presently in the two ears (bilateral).
  • Pre-lingual or Post-lingual
  • The hearing loss happened before anyone learned to communicate (pre-lingual) and it also occurred after someone learned how the art of speaking (post-lingual)
  • Symmetrical or Asymmetrical
  • The loss of hearing is identical across both ears (symmetrical) or it differs between the two ears (asymmetrical).
  • Progressive or Sudden
  • Hearing loss may become worse over the duration (progressive) or it can happen quickly (sudden).
  • Fluctuating or Stable
  • Hearing loss can become greater or lesser severe with time (fluctuating) or stays constant throughout the duration over the duration (stable).
  • Congenital or Acquired/Delayed Onset
  • Hearing loss is present at the time of the birth (congenital) or it may develop later in the course of (acquired or delayed starting).
