Abstract
Feedback reduction in hearing aids is simplified and improved in an amplification device that has two separate compensation paths, an acoustic input and an inductive input. In the first compensation path, a first filter device acts to compensate acoustic feedback, and in the second compensation path, a second filter device acts to compensate inductive feedback. The two very different feedbacks can be individually compensated without increased outlay.
