Feedback Cancellation delivers greater stability

2Pi’s robust feedback cancellation is designed to liquidate acoustic feedback resulting from a system’s instability at high amplifications. The automated and fully adaptive system provides up to 18 dB of added stable gain.

Stops the whistle

Feedback, or whistling, is eliminated by accurately estimating a feedback path in terms of magnitude and phase and extracting it from the incoming signal. This method applies to a variety of feedback situations - algorithm can be implemented in a wide range of branded products: hearing aids, hearing protection devices, and listening devices with conventional headphones.

A complete set

2Pi’s feedback prewarning tool is a natural extension to the feedback cancellation algorithm, that prevents applied gains from going beyond the critical point and generating feedback.
