Oticon Hearing Aids by Karn Dhwani Enterprises

Description

In all hearing aids, sound enters through a microphone. It is then processed, amplified and delivered to a receiver (loudspeaker). This sends the output either directly to the user’s ear canal, via tubing to an earmould and into the ear canal, or via a thin wire to a receiver placed directly in the ear.

There are two types of sound processing:

• Analogue
• Digital

In analogue instruments, sound is processed as an electrical signal by a microphone.  Analogue sound is like making a photocopy: the sound is registered and you get an overall picture. But the actual processing is like recopying a photocopy – it can only be done to a certain extent because it causes a deterioration of the original imprint.

In a digital hearing aid the acoustic signal is converted into digits (0, 1), processed within the hearing aid, and then reconverted to an analogue acoustic signal for the listener. A digital signal can be repeated endlessly without affecting the overall quality. It is like making copies of a scanned image: each copy is a perfect duplicate of the original.

As an extension to digital sound processing, Oticon’s RISE architecture represents a paradigm shift in the hearing aid industry: it offers wireless connectivity and high-speed broadband interoperability between instruments. With RISE two hearing instruments can communicate and perform binaural processing, allowing them to work as one central processor.

This brain-like behaviour provides a more authentic listening perspective. In addition to pushing the limits of how hearing instruments process sounds, RISE allows people to connect to a number of Bluetooth enabled electronic devices such as mobile phones, MP3 players etc.
