Bone conduction hearing aid transmits vibration from the HA to the human bone (skull). Patients with abnormal ear-shape, no pinna can be used this.

Base on development of convention HA, there was 3 types:

3. Type of modern hearing aids

Modern hearing aid has many types of wearing

– BTE (Behind The Ear): the hearing aid is worn on and behind the pinna. The sound is transmitted through tube with a customized mold put in the ear canal. This type of hearing aid normal has high power (super power, ultra power) of amplification.

– RIC (Receiver In the Canal): same wearing as BTE, however the sound is transmitted through the wire to the receiver (a very small speaker) which is put in the ear canal. This type of hearing aid is smaller than BTE type with varietal power of amplification. This type is the most wanted hearing aid today.

– ITC (In The Canal), ITE (In The Ear), CIC (Complete In the Canal): all-in-one hearing aid with compact size can fit inside the canal. This type of hearing aid bring cosmetic wearing option, however it’s limited in power of amplification and features. 

– Bone conduction hearing aid has different wearing than conventional hearing aid. The vibration plate should be place on the area where we can feel bone beneath the very thin skin. And need some accessories to wear like adhesive adaptor, headband, soft-band, spectacle adaptor.
