Abstract

The acoustic amplifying system comprises feedback compensator (1) of signal generated during amplifying of input signal (3) on feedback path (7) from amplified output signal (11) to input signal. An adaptive feedback compensation filter (15) generates a compensation signal (8) based on amplified output signal. At least one first filter (13,21,23) limits the frequency range for compensation signal. The first filter(s) is adaptable in its function during operation of feedback compensator. Independent claims are included for compensation method for feedback signal and for hearing aid.
