6mkgar | Why audiologists don't suggest bone conduction technology over cochlear implants? | brief context: I'm deaf in my right ear. The doctor suggests implants but I'm not eligible for them where I live. But bone conduction works for me, so I'm curious why I wasn't pointed towards the technology earlier. Is it something to do with the age of the tech, or just limited application? | Technology | explainlikeimfive | {
