Hearing loss

Hearing loss can occur very gradually and many people don’t notice it happening until it has become quite pronounced. However, this may be obvious to the people around them.

How Do We Hear?

Hearing is a complex process, which involves travelling of Sound through the ear canal to the eardrum causing it to vibrate. These vibrations are transferred to three small bones (malleus, incus and stapes) in the middle ear. When the stapes vibrates, it causes movement of the cochlea fluid in the inner ear which stimulates the sensory cells for hearing. Stimulation of these sensory cells generates an electrical signal which travels to the brain via the auditory nerve. This is how we hear.

The human ear can be functionally divided into four main sections: the outer ear, the middle ear, the inner ear, and beyond the inner ear (retro-cochlear) 

Types Of Hearing Loss

The three primary types of hearing loss are conductive, sensorineural and mixed.

Conductive hearing loss occurs when sound is not conducted efficiently through the ear canal to the eardrum and the tiny bones (Ossicles) of the middle ear.

Sensorineural hearing loss occurs when there is damage to the inner ear (cochlea) or to the nerve pathways from the inner ear to the brain.

When a conductive hearing loss occurs in combination with a sensorineural hearing loss, the hearing loss is referred to as a mixed hearing loss. In other words, there may be damage in the outer and/or middle ear and in the inner ear (cochlea) or auditory nerve.

Signs of Hearing Loss

  • Muffled quality of speech and other sounds
  • Difficulty understanding words, especially against background noise or in a crowd of people
  • Difficulty understanding people unless they are facing you
  • Thinking that others do not talk properly and mumble
  • Frequently asking others to speak more slowly, clearly and loudly
  • Difficulty understanding women and children’s voices
  • Struggling to hear conversation from a distance
  • Needing to turn up the volume of the television or radio
  • Difficulties hearing on the telephone
  • Avoidance of some social gathering
  • Missing the telephone or door bell
  • Hearing well in private settings, but not in groups
  • Becoming more sensitive to loud sounds
  • Experiencing ringing in the ears

Causes Of Hearing Loss

Hearing loss in adults has many causes, such as disease or infection, ototoxic drugs, exposure to noise, tumours, trauma, and the aging process.

Hearing Assessment

A number of tests are available to discover the nature of a hearing difficulty and to help determine effective treatments. The tests include Pure Tone Audiometry (PTA), Speech Discrimination Test and Tympanometry.

Benefits of Treatment

Individuals who have hearing loss are treated by wearing hearing aids, the benefits of wearing hearing aids include:

  • Better relationships with family members
  • Better feelings about themselves
  • Improved mental health
  • Greater independence and security
  • Significant improvements in the quality of their lives

Studies show hearing impaired people who do not wear hearing instruments are more likely to experience depression, anxiety, paranoia and emotional sickness, compared to people who wear hearing instruments.
