About Hearing Loss

About Hearing Loss

The inability to listen and understand speech and other sounds can occur in any individual, regardless of race, gender or age. In United States alone, an estimated 28 million people have some form of hearing impairment, and more than a million school going children have a hearing loss that can significantly impact their speech/language development and education.

Hearing loss can be temporary or permanent, mild or profound. Fortunately, in most cases, something can be done to improve the hearing impaired person's ability to communicate. Hearing Aid is the best non-surgical option for hearing impaired person to reconnect to the world.


How We Hear

The ear has three main parts or sections - the outer ear, middle ear and inner ear. Each section has a specific function that allows sound waves that enter the ear to be transformed into electrical signal that brain can understand. The outer ear collects sound waves and directs them to the middle ear. The middle ear then amplifies the sound and transmits it to the inner ear. The inner ear converts the sound vibrations into electrical impulse that travel along the auditory nerve to the brain.Hearing mechanism involves following steps-

  • The outer ear catches sound waves and directs them into the ear canal.
  • The ear canal carries the sound waves to the eardrum (tympanic membrane).
  • Sound waves cause the eardrum (tympanic membrane) to vibrate.
  • The bones in the middle ear (malleus, incus and stapes) pick up these vibrations.
  • Vibrations pass through the oval window to the cochlea, setting the fluid inside in motion. This causes special nerve cells to turn the sound waves into electrical impulses.
  • The auditory nerve sends these electrical impulses to the brain where they are heard as sound.
