Digital Hearing Aids

Oticon Delta Digital Hearing Aid

The Oticon Delta is a relatively new concept in "open fitting" hearing aid design. Introduced in 2006, it targets those with mild high frequency hearing loss, (about 20 – 30 percent of the hearing aid market).

The Delta consists of two parts—the electronic amplifier, enclosed in a tiny delta shaped behind-the-ear aid, and a tiny transducer (receiver) so small that it fits entirely in the ear canal close to the ear drum and is connected to the hearing aid by a very fine, almost invisible copper wire.

The unit shown in the picture is not an actual hearing aid, but rather a display sample produced by Oticon to distribute to prospective consumers.
