Speech contains both high-frequency and low-frequency sounds. The high frequency sounds are the key to understanding speech. Unfortunately, providing high-frequency amplification in hearing instruments can result in feedback (whistling).

Most hearing aids address feedback by reducing the high-frequency amplification which ultimately compromises speech understanding.

Adapto Power deals with feedback in a totally different way. The Dynamic Feedback Cancellation (DFC) system controls feedback without reducing high-frequency amplification.

So feedback is eliminated before you ever hear it.

How does the DFC system work?

The Dynamic Feedback Cancellation system constantly monitors the sound you hear through your hearing aids when it detects the slightest sign of feedback, it immediately cancels it out.

The system operates in two different modes – Fast and Slow. The Slow mode is appropriate for most situations and consumes very little battery life. The Fast mode is for situations where sudden changes occur, like when you’re hugging someone or answering the telephone. This system provides double security against feedback.
