That is not new technology at all. Audiologists have been using it to test bone conduction hearing as part of standard hearing tests for decades. Some people who don’t have ear canals wear bone conducted hearing aids. Usually the vibrator sits on the mastoid bone right behind the lower part of your ear, not in front of your ear. If you put it in back of your ear, it will have a more direct route to your inner ear (cochlea) and require less power. One thing about BC phonestheir frequency response is limited, compared to air conducted phones (through the ear canal). The have much more power in the lower frequencies, and very little power for the higher frequencies. The batteries used are hearing aid batteries, and most hearing aid batteries last about 30 days.
