Hearing device

Abstract

The hearing device takes advantage of a simultaneous three-pronged approach that converts sound to electricity and subsequently to vibration and ultrasound. The vibrations and electricity are transmitted via skin nerves to the brain to give the deaf or hard of hearing person “hearing sensation” through conditional reflex. The ultrasound wave is transmitted wirelessly to skull and then via bone conduction to the brain and inner ear. This hearing device is not solely dependent on the partially or totally damaged or absent inner ear.
