The term “hard of hearing” refers to citizens who have serene to severe hearing loss. Hearing aids, cochlear implants, and other assistive devices, such as captioning, can be beneficial for a community.

Citizens who are “deaf” have profound hearing loss, which means they have small or no hearing. Subscribe to a language to communicate with them.

It can happen when any ingredient of the auditory (hearing) scheme is not working.

Infections and diseases

In these cases, treatment should not be delayed. Even washing with impure water can trigger an ear infection and these links. Childhood illnesses like measles, whooping cough, and mumps may bring on deafness.

There are four types of hearing loss:

1. Conductive refers to the inability of sound to pass through the outer or middle ear. It must have medication or surgery to treat this.

2. Sensorineural

3. Combination consultations for conductive and sensorineural hearing loss.

4. Auditory Neuropathy

It occurs when sound enters the ear. The sound normally hurts the inner ear or the hearing nerve, but somehow the brain processes it.

The outer ear

The outer ear is smooth and:

It is the portion we see on the sides of our heads, known as the pinna.

Ear canals

The membrane that separates the outer and middle ear is called the tympanic membrane.

A middle ear infection

The middle ear consists of:


The movement of the eardrum is transmitted to the inner ear by three bones, called ossicles.

Ear Inner

  • The inner ear consists of:
  • The cochlea is a snail-shaped organ for hearing
  • Nerves that lead to the brain
  • Auditory (ear)
  • The nerve transmits sound databases from the ear to the brain.
  • (Auditory) System

The symptoms

The following are efficient Techniques for reducing hearing loss at diverse stages of life:

  • Vaccination;
  • Maternal and childcare practices;
  • Counseling on genetics;
  • Identification and treatment of current ear conditions;
  • Noise and chemical exposure programs for occupational hearing conservation;
  • Strategies for reducing exposure to loud sounds in recreational settings;
  • Preventing ototoxic hearing loss through the rational use of medicines.

Identifying and managing

The key to efficient management of ear diseases is before time detection.

Narrated ear diseases in the vast majority of vulnerable, systematic screening required. Added are:

  • Newborns and infants
  • Children in pre-school and school
  • Those exposed to blast or chemicals at work
  • Those taking ototoxic medicines
  • Adults more than the age of 65

Clinical and community settings are accessible for hearing assessments and ear examinations. The “hearWHO” app and other technology-based solutions make it possible to veil for ear diseases and extremely restricted training and resources.

Following measures :

  • hearing technologies, for example, hearing aids, cochlear implants, and middle ear implants.
  • Sign language and other sensory substitution methods, such as speech reading, palm or Tadoma printing, and subscribed communication;
