Hearing aids. Artwork showing different types of hearing aid. Clockwise from top left these are; body worn, behind the ear, in the ear and in the ear canal types. Hearing aids improve hearing in people with partial deafness. Sound is picked up by a microphone, amplified and transmitted into the ear by speakers. Each aid is fine-tuned to amplify the range of frequencies most needed by the patient.
