How the Sophono Hearing Aid Works.

Implantable magnets are used to secure the sound processor behind the ear. The device consists of three elements: 1. A titanium implant containing two magnets 2. The externally worn sound processor and 3. External magnets with varying strengths to ensure comfort and safety. The system transfers sound to the inner ear via the bone, bypassing the outer or middle ear. Candidacy is restricted to individuals with mixed hearing loss, single sided deafness, and malformations of the external or middle ear .
