#4: Virtually Eliminates Feedback
Current Hearing Aids
Feedback is the result of sounds leaking from the hearing aid speaker back into the microphone, which then becomes amplified to the point where they cannot be amplified any more. A loud, painful squeal or whistle is produced. It’s the same issue found in an auditorium when a microphone is placed too close to a speaker.
Many hearing aids on the market today use a mechanical approach when addressing feedback. A tight, oversized hearing aid shell is produced in an attempt to form a tight seal between the hard hearing aid shell and the soft ear canal walls. The result may be an uncomfortable fit and despite the effort, feedback may still occur.
Zounds Difference
Zounds hearing aids utilize an electronic solution when dealing with feedback. Zounds' sophisticated feedback cancellation identifies the amplified sound leaking around the hearing aid and electronically eliminates most of it before it can squeal.
