Experience has shown that the Multi-directional active feedback cancelling system in Widex hearing aids is extremely efficient in controlling dynamic feedback problems.
Moreover, with the introduction of our InterEar hearing aid series, CLEAR and SUPER, we have managed to make our industry leading system even more precise. Specifically, when an external, auto-correlated sound (i.e., a sound with a repeating pattern) like a whistle or an alarm is picked up by the hearing aid, the InterEar coordination between the hearing aids means that Dynamic Cancellation Optimiser is able to compare detected sound from both sides of the head.
If the feedback-like signal is the same on both sides, it can be deducted that it is an external sound rather than a feedback signal. Thus, with InterEar feedback cancelling, we are able to avoid unnecessary gain regulation resulting from “false positives”.
