What is it?
A contact Mini bone conduction hearing device allows the sound to be conducted to the cochlea (inner ear) through the mastoid bone. It does this by the microphone picking up the sound that is then carried through the wire to the transducer, which is placed on the mastoid bone. The transducer then converts sound into vibrations that travel through the bone to the cochlea.
These devices are often suitable for some children with a conductive hearing loss due to recurrent ear infections or glue ear.
How to wear this device?
The device can be worn on a soft band or hard band. The vibrating transducer will sit on the mastoid bone behind the ear and the microphone should be at the top, uncovered.
The band should fit snuggly and be a comfortable fit for most effective sound transmission.
Daily checks:
- Turn the hearing aid on, cup the transducer in your hand and speak into the microphone. Is the transducer vibrating?
- If yes, Place the hearing aid on your child’s head, make sure it is placed correctly (as shown above).
- Ensure battery drawer is locked before fitting the hearing aid.
- Ensure battery drawer is locked before fitting the hearing aid.
