According to the World Health Organization (WHO), by 2050, numbers of people with hearing loss will jump to nearly 900 million. According to local doctors, with the aging population significantly increasing, hearing aids Indianapolis IN will become more of a necessity.
About half of the older people, over the age of 75, have a certain degree of hearing loss, also called hyperacusis, with possible consequences on their quality of life. This condition leads to a decrease in the interest in listening to radio and television, moreover, it often leads to social isolation and loss of interests in activities, as well as a loss of self-esteem. Many develop a depressive mood disorder.

How Hearing Loss Occurs

Hearing loss gradually manifests over time. Mostly it is difficult to perceive the acutest tones (chirping, doorbell, telephone sound). With the worsening of symptoms, the difficulty in perceiving the low-pitched sounds like that of an engine roar is also lost.

Symptoms of hearing loss for most people include:

  • some sounds seem too loud;
  • problems to hear if there is background noise;
  • problems to understand above all the voice of women or children;
  • greater difficulty in hearing acute sounds
  • the impression that many people do not speak clearly;
  • the impression of hearing hisses or little bells

Hearing Loss Causes

Within each ear, there are about 16 thousand cells provided with small hairs, the ciliated cells, which have the function of intercepting the sound waves and transforming them into nerve impulses to be sent to the brain. The ciliated cells are not able to regenerate when they happen to be damaged or die. This is why most of the hearing losses are permanent.

In addition to aging, other causes that can contribute to hearing loss are hereditary factors, the abuse of certain drugs, hypertension and atherosclerosis. Another common cause is exposure to intense noise if protracted over the years.

Diagnosis And Aids

Hearing aids are now extremely customizable according to the needs of the patient, and their miniaturized and handy for convenience.

Can Hearing Loss Be Prevented?

Overall, there are limits to how we can protect the aging ear, but we can certainly limit exposure to things that contribute to hearing loss.
