In today’s modern technology, hearing aids need not necessarily be visible outside one’s ear. There are a range of hearing instruments such as CICs (Completely in the Canal) and IICs (Invisible in the Canal) that are almost impossible to see under normal conditions. These hearing aids use the latest digital technology and are custom made to fit individual contours of the person’s ear canal. Unlike other hearing aid types, the sound can be collected more naturally by the shape of the ear, and can travel down into the ear canal as it would with unassisted hearing.
