Hearing Aids

• Hearing aid is an electronic device which
  amplifies sound to aid people who have a hearing
  problems

How a hearing aid works

• A microphone picks up sounds.
• Sounds are analyzed by the processing chip.
• Processed sounds are sent to the amplifier.
• Amplified sounds are sent to the loudspeaker.
• Sounds are transmitted by the loudspeaker into
  the inner ear where they are transformed into
  electrical impulses.
• Impulses are picked up by the brain where they
  are processed.

Difference between analog and digital hearing aids

• Analog hearing aids make continuous sound waves
  louder. These hearing aids essentially amplify
  all sounds (e.g., speech and noise) in the same
  way. Analog hearing aids are becoming less and
  less common.
• Digital hearing aids have all the features of
  analog hearing aids, but they convert sound waves
  into digital signals and produce an exact
  duplication of sound. Digital hearing aids
  analyze speech and other environmental sounds.

How digital hearing aids work

• Unlike analog aids, in digital hearing aids,
  sound enters the device is broken into multiple
  frequency bands. Each band is then amplified by
  the amount necessary to return the wearer's
  hearing to normal levels at that band.
• With digital technology, devices can now break
  sound into as many as 48 different bands. This
  feature makes the sound quality provided of a
  digital hearing aids far better than the analogue
  technologies.

• This model combines the advantages of both the
  behind-the-ear and custom (in-the-ear) models.

  and is connected to the main body of the hearing
