Experience natural sound with less distortion
Benefit from improved speech understanding, and localised sound. Hearing with bone conduction results in a natural sound with less distortion and feedback when compared with conventional hearing aids.
What Are Bone Conduction Hearing Aids?
A bone conduction implant is a medical device that transmits sound by direct conduction through bone to the inner ear, effectively bypassing the outer and middle ear. A bone conduction system consists of a small titanium implant, abutment and sound processor. Sound is transmitted as vibrations from the sound processor to the implant, through the bone to the inner ear.
Bone conduction implants can help people who have:
- Conductive hearing loss
- Single-sided deafness (SSD) – total hearing loss on one side
- Mixed hearing loss
How can they help you?
For problems in the outer or middle ear, bone conduction hearing aids can help you hear better in noisy situations and allow you to localise sounds.
Not only do you benefit from improved speech understanding, hearing with bone conduction results in a natural sound with less distortion and feedback when compared with conventional hearing aids. The ear canal is left open for comfort, and helps to reduce any problems caused by chronic ear infections or allergies.
If you are completely deaf in one ear, a bone conduction implant works by sending the sound via the skull bone from the deaf side to the functioning inner ear on the hearing side. This transfer of sound gives you 360-degree sound awareness.
Fitting Bone A Conduction Hearing Aid
- Following referral to the Hearing and Balance Centre, a full audiological assessment will be carried out – including an audiogram (air and bone conduction test), a speech recognition test, a BAHA rod test and speech recognition testing with a BAHA simulator.
- You will be given a BAHA simulator to take home and try in your own environment.
- Following the assessment procedure and consultation with your ENT surgeon you will be advised if you are a suitable candidate for the BAHA. You can then make an informed decision about whether to proceed with surgery or not.
- If you decide to proceed, the BAHA speech processor (hearing aid device) will be connected approximately 6 weeks after surgery. This waiting period is required for the bone to integrate with the titanium abutment allowing a secure fixture for the BAHA to be connected to.
- On your switch-on day, the audiologist will check the area around the abutment, making sure it is ready for the BAHA to be connected. The use and management of the device will be extensively discussed and practiced. The sound quality and level will be programmed to suit your hearing loss.
- The audiologist will monitor your progress and make some adjustments (if necessary) in the following months for a period of about 6 months.
