You do not want your hearing to be like a Jimi Hendrix show, with feedback blaring. Perhaps that is the reason for your hearing loss. Regardless of the cause, digital feedback reduction is an excellent feature of digital hearing aids. It controls any feedback that may be developing in a sonic environment before it makes the listener's ears. Feedback typically happens when the wearer gets too close to something, or sometimes when the user's jaw makes particular movements.

While digital noise reduction takes out undesirable noise from the same direction as the source of the desired sound, digital speech enhancement acts to step-up the level of the desired root of sound, whether it be a person talking to the user or a TV program on the television set across the room. This processing is a new aspect of hearing aids, because the complexity of it has just recently been mastered by sound engineers.
