Latest Condution Hearing System Work.

How bone conduction hearing
systems work

Bone anchored hearing systems are designed to use your body’s natural ability to transfer sound through bone conduction. The sound processor picks up sound, converts them into vibrations, and sends them through your skull bone, directly to your inner ear. This bypasses any problems in your ear canal or middle ear.
A bone anchored system consists of three parts:
  1. A small (3 or 4 mm) titanium implant that sits in the bone behind the ear
  2. An abutment that juts out through the skin
  3. sound processor

The sound processor connects easily to the abutment with a simple click.  Whenever you need to remove it – prior to showering and sleeping etc – just click it off again.

 

How it works

The sound processor picks up sound waves in much the same way as a conventional hearing aid. But instead of sending them through your ear canal, it transforms them into sound vibrations and sends them, via the abutment and implant, through your skull.
In this way the vibrations travel directly to your inner ear, bypassing any problems in your outer and/or middle ear.  

Single sided deafness

As sound via bone conduction is always transmitted to both ears, a bone anchored hearing system can also benefit people with single-sided deafness. It picks up sound on the deaf side and transfers it to the good ear.
