How bone conduction implants work

A bone conduction implant system can bypass damaged or blocked parts of the ear and deliver vibrations directly to the inner ear. The inner ear converts the vibrations to electrical signals that the brain interprets as sound.

Bone conduction implants work by using the body’s natural ability to conduct sound. They are designed for people with single-sided hearing loss, conductive hearing loss or mixed hearing loss.

There are three parts to a bone conduction system:

  • a small titanium implant that is surgically inserted in the bone behind the ear
  • an abutment or a magnet that connects the implant to the sound processor
  • an external sound processor.


Together, these parts bypass the section of the ear that isn’t working, sending vibrations directly through the bone to the inner ear.


Can bone conduction implants help your child?

Bone conduction implants may help children with single-sided hearing loss, conductive hearing loss or mixed hearing loss.


What are the benefits?

Research and decades of experience shows that bone conduction implants may help children with these types of hearing loss:

  • Hear better, even in noisy situations.1,2
  • Enjoy improved sound quality (compared to hearing aids) by bypassing the damaged part of their ear to reduce the amount of amplification needed to hear better.2
  • Enjoy improved speech recognition (compared to hearing aids).3


A hearing professional who specialises in hearing implant technology can advise if your child could benefit from a bone conduction implant.


Are there bone conduction solutions that don’t need surgery?









Yes. The Cochlear™ Baha® System allows your child to experience all the benefits of bone conduction even if they are too young for an implant or not quite ready for surgery.

The Baha® Softband and SoundArc™ are non-surgical solutions that may give children the hearing performance they need to help develop language skills.4 Both work with any of the Baha sound processors.


Benefits for your child

Early access to sound is proven to make a difference in helping children learn, engage and fully experience the richness of their environment.5 Baha Start may be the solution your child needs to access sound as early as possible. It’s designed to deliver sound to help your child to develop on par with their hearing peers.4,5

With our latest sound processor, Baha 6 Max, your child will have a small and powerful sound processor designed to deliver clear, rich and natural soundwithout getting in the way of their everyday life.









Different ways of connecting to your hearing

There are two connection options for the Baha System: Baha® Connect and Baha® Attract.

The Baha Connect System is an easy-to-use and effective7,8 hearing solution designed to improve your hearing.

It uses a small abutment behind the ear that connects the sound processor directly to the implant to maximise the sound that gets through to your inner ear. You simply snap your sound processor onto the abutment and can get on with doing the activities you enjoy.

The Baha Attract System is a comfortable and easy-to-use9 hearing solution that uses magnets to hold the sound processor over the implant. The sound processor then sends sound through to your inner ear.

You simply place your sound processor (with sound processor magnet) over the implant and then you can get on with your day while experiencing the sound around you.


A range of Baha sound processors

The Baha System includes sound processors for different levels of hearing loss, so you can get one that is right for you. And should your hearing loss change over time, more powerful processors may be available, so you can continue hearing your best.



Small never sounded this powerful









The Baha 6 Max is a premium-power bone conduction sound processor that doesn’t compromise. It’s designed to provide clear, rich and natural6 sound in a small and discreet package.

The power levels have been increased to provide access to a broad and dynamic range of sounds that are linked with the improved ability to hear in noisy environments.10 And we added a new chip that lets you stream directly from both Android™ and Apple devices.
