The feedback challenge

Feedback in Super Power instruments can cause a number of persistent problems.

1. It can distort the signal across all the frequencies, thereby affecting the sound quality
2. Feedback can be so annoying that it can force the child to reduce the volume – thereby depriving him or her of vital speech cues
3. Rapid ear canal growth can demand numerous earmold remakes

Instead of reducing the volume to avoid the problem, Sumo uses Dynamic Feedback Cancellation. This system eliminates feedback without reducing gain.
