What is "Feedback" and How Do Digital Hearing Instruments Help Deal With it?

"Feedback" is the annoying whistling sounds that you may hear when you cup your hand around a hearing aid, or when the hearing aid is not seated securely in one's ear canal. Feedback occurs when the sounds amplified by the hearing aid returns to the hearing aid and is re-amplified many times. Wearers of analog hearing aids usually turn down the volume on the hearing aid to stop the feedback. This, of course, makes it difficult for the wearer to hear the intended sounds. Many digital hearing aids, however, are designed to minimize this problem. The hearing aid monitors the sounds that goes in and comes out to check for feedback. If feedback is identified, it will work to cancel the feedback whistle-automatically. This not only removes the annoyance caused by feedback, but also allows the wearer to use the hearing aids as intended with excellent sound quality.  more

If feedback is identified it will work to cancel the feedback whistle automatically!
