Asius Technologies has created a revolutionary, inflatable in-ear audio technology, the Ambrose Diaphonic Ear Lens (ADEL™). When used in hearing aids, headsets and ear buds, the ADEL™ gives the user a richer sound quality, a custom fit, and a safe listening experience.

Asius Technologies has invented a revolutionary new approach to reproducing sound in the ear, involving small micropumps and unique inflation devices (patents pending).  We call it ADEL Technology, which stands for Ambrose Diaphonic Ear Lens.  Ambrose is the name of the principal technology inventor, Stephen Ambrose, Diaphonic comes from the Greek words meaning through sound, and Ear Lens describes the fact that the technology allows adjustments of sound coupling to the hearing system as does a camera lens our sight.

In combination with a variety of sound reproduction transducers, ADEL devices seal in desired sounds, seal out undesired sounds and control the coupling of energy to the cochlea by means of bone conduction as with natural human hearing. These seals are created and maintained at safe pressures, lower than those associated with “clearing your ears” during an airplane flight.

In addition to sealing the ear canal and coupling sound energy into the hearing system, ADEL devices perform these functions with extreme comfort and a significant reduction of the occlusion effect.
