Artificial ear - a wearable device for the hearing impaired

Hearing aid devices have been around for decades, and one of the most recent approaches is the cochlear implant which is designed for patients with severe hearing loss. This paper introduces the design of a haptic-signal based hearing aid targeting patients suffering from inner ear malfunction, for which the conventional assistive hearing devices will not suffice. This device is designed to record the incoming sound, filter and analyze it into its harmonics, and classify it into the phonemes. The output is transfer into tactile feedback with vibrating motors and each phoneme will activate the respective combination of them.
