It’s time to hear
what you’ve been missing.

Everyone has a different story

Perhaps you woke up one morning and found that you couldn’t hear on one side. Maybe you went through childhood struggling to hear even though you tried hearing aid after hearing aid.

Hearing implants work differently to normal hearing aids, and depending on your situation, could make a positive impact on how well you can hear and communicate.

After struggling with hearing loss for years, Chris can’t imagine living life without the Cochlear™ Osia® System.

“Just not having to ask things again, or to miss parts of conversation, makes my day run a lot smoother. And to be able to hear sound on both sides makes my hearing more complete.”

Adrian, Cochlear Osia System recipient*

What is single-sided deafness?

Single-sided deafness (SSD) is the loss of all or almost all hearing in one ear.

You can be worn with SSD, it can happen suddenly or over time. It makes locating sounds and hearing in noisy environments difficult. The hearing loss associated with SSD is sensorineural, when the inner ear – or less often the hearing nerve – isn’t working correctly.

Although SSD cannot be cured, there are solutions that may restore the sensation of hearing from both sides.

What is bone conduction?

When we think of hearing, we think of our ears picking up sound, but did you know that we can also hear sound via the skull?
Bone conduction is a term to describe how sound waves travel through the skull to reach the inner ear.

Cochlear Acoustic Implants work on this principle of bone conduction and use the skull to send clear, crisp sound¹ directly to the inner ear, completely bypassing the middle ear. The sound processor picks up sound and sends it to a vibrating element, called the transducer. The transducer, connected to a small implant fused with the bone, sends the sound as vibrations to the inner ear. They are then converted into electrical impulses which are interpreted by the brain as sound.

How can bone conduction help me?

Cochlear hearing solutions that use bone conduction pick up sounds from your deaf side and send them directly to the inner ear on your hearing side, via the bones of your skull.

The benefits include:

  • Clearer and more crisp sound1 than with hearing aids
  • Better speech understanding in noise than hearing aids2,3
  • Hearing with two ears allows you to identify sounds both near and far, as well as those that occur around your head.4

How is hearing through bone conduction different from CROS hearing aids?

Contralateral routing of signal (CROS) hearing aids can be a solution for SSD. With a CROS hearing aid, you wear a device in both ears. A microphone placed on your deaf side, transmits to a receiver on your hearing side.

 

Hearing through bone conduction

  • Better speech understanding in noise2
  • Can be worn on one side
  • Sends sound directly to your inner ear

CROS hearing aids

  • Needs to be worn on both sides
  • Sends sound via the outer and middle ear to your inner ear

Recipient stories

Adrian, Cochlear Osia System recipient*

Adrian is a 50-year old psychiatric nurse and passionate singer. The Osia System has made his life easier and given him more confidence at work.

“I felt this sense of relief… It was more a sense of completeness, and not having to impose a little bit on people and ask them to repeat themselves. Just being able to engage like a full hearing person, it’s hard to explain.”

 

 

Cynthia, Cochlear Baha® System recipient*

Cynthia woke up on the 4th of October realising something was terribly wrong. She could no longer hear out of her left ear. When she tried the Baha System she felt a sense of wholeness again and decided to go for surgery.

“With this amazing technology I’ve been able to really live my life normally and haven’t had to compromise in any way.”
