Hearing Aids are worn behind the ear. The hearing aids consists of three essential parts -

Hearing Aids
  • Microphone- converts the sound saves into electrical signals and sends them to the amplifier.
  • Amplifier- increases the power of the signals received from the microphone.
  • Speaker – sends the signals to the ear.

Hearing aids are helpful to people with a sensori-neural hearing loss i.e. loss which results due to damage of the sensory cells (hair cells) in the inner ear.

Important Causes of hearing loss –

  • Old age
  • Disease
  • Injury- due to loud noise or medicines

A hearing aid magnifies the sound waves entering the ear. The existing sensory cells detect the sound vibrations, convert them into neural signals and transmit it to the brain.

Greater the damage to the sensory cells- greater is the hearing loss- greater is the need for sound amplification.

General practitioners generally refer patients with hearing loss to an audiologist or otolaryngologist.
