How bone anchored hearing aids (BAHAs) work
These hearing aids are used when hearing cannot be transmitted through air and through the middle ear.
With a BAHA, sound is transmitted through the bone of the skull directly to the cochlear in the inner ear. BAHAs work most effectively when the speaker is within 2 metres.
A BAHA is fitted via surgery.
How to check a BAHA is working
Check the battery every morning. Hold the hearing aid in your hand. You should be able to feel the hearing aid vibrating when you talk. If it doesn’t, change the battery and try again.
Ask the child to turn round so they can’t lip read. Give a simple instruction and check for appropriate response.
Ongoing management
The sound processor is battery operated and batteries need to be changed regularly.
Be aware that the site of the BAHA can be prone to infection and may become sore. Report any impact to the site of the BAHA to parents.
Make sure you are familiar with health safety implications of the BAHA. Ask parents or your Teacher of the Deaf.
