Method and apparatus for feedback reduction in hearing systems
Abstract
amplifier device for hearing aids with an amplification (1) having an acoustic input and an inductive input, and a filter system (8) which is connected to the amplification system (1) for compensating one acoustic feedback, characterized by a second filter (10) which is connected to the amplification system (1) and which is different from the first filter (8), for compensating an inductive recoupling, and data communication (12) between the first filter (8) and the second filter (10) for transmitting filter coefficients.
