The primary function of implantable hearing aids, specifically bone-anchored hearing aids (BAHA) or similar devices, is to vibrate the middle ear bones directly. These devices bypass damaged areas of the ear by transmitting sound vibrations through the bones of the skull, which then stimulate the inner ear directly. This method is particularly beneficial for individuals with conductive hearing loss, where sound cannot be effectively transmitted through the ear canal due to blockages, malformations, or other impediments.

In contrast, amplifying sound delivered to the eardrum relates more to traditional hearing aids, which rely on microphones to pick up sounds, amplify them, and then deliver this amplified sound into the ear canal. The function of transmitting sounds through a cochlear implant is different, as cochlear implants bypass the damaged hair cells in the cochlea by directly stimulating the auditory nerve, rather than vibrating the middle ear bones. Additionally, enhancing sound in quiet environments does not accurately capture the primary operation of implantable hearing aids, which focus on direct stimulation rather than just amplification or enhancement of ambient noise.
