The audiologist will fit and program the BAHA device’s external components to your unique hearing situation. The programming system is called mapping; maps are programs that are customized for the user’s implant. Frequent customized mapping provides the best hearing experience for the user. The way the audiologist performs mapping is by using beeps to adjust the device’s processors.
BAHA is suitable for those with conductive hearing loss, unilateral hearing loss, single-sided deafness and mixed hearing losses due to damages to the middle or outer ear. This is because the BAHA system bypasses these features and transfers sound directly from outside the head into the inner ear.
It is possible to test the BAHA system to see if it will work for you. Your doctor can connect the BAHA sound processor to your head via headband, which will provide a similar hearing experience as the implant.
