  • If you are the one who probably heard about
    digital hearing aids but did not fully understand
    its mechanism and how it would work best for your
    hearing loss, just go through this presentation
    to know what are digital hearing aids and what
    makes them different?

3
  • The most basic function of a hearing aid is to
    amplify sound. Digital hearing aids use computer
    technology

4
How do digital hearing aids work?
  • Digital hearing aids break sound into as many as
    48 different bands. Given that every person has a
    unique pattern of hearing loss, the sound quality
    provided by a modern hearing aid is far better
    than the previous analogue technologies that were
    restricted to two bands - base (low frequencies)
    and treble (high frequencies)

Digital Hearing Aids Mechanism
  • Hearing aids receive sound through the
    microphone. Distortion and noise are added to the
    sound from the microphone.
  • The sound is then sent to the amplifier, where
    the digital device measures the sound and decide
    how much power to add in order for you to hear.
  • After being amplified, the sound is sent to the
    receiver ( the speaker ) and is then cleaned up
    again before being sent to your ear. This is also
    where digital instruments look for feedback (
    whistling ) and work to cancel it before the
    feedback happens.

Digital hearing aids advantages
  • More comfort
  • Digital feedback reduction
  • Digital noise reduction
  • Digital speech enhancement
  • Directional microphones

8
  • Digital hearing aids are said to offer the user a
    more accurate reproduction of sound, resulting in
    superior sound quality
