Abstract (en)
[origin: EP1401242A2] An estimation device (6 to 11) is connected between a signal input device (3) and an acoustic feedback reduction device (5,12,13,14), and is used to determine an estimate of the system noise-free level, defined by the separation of the loop gain of the fed-back system from its stability limit, so that parameters of the feedback reduction device can be controlled based on the estimate. An Independent claim is included for an acoustic feedback compensation method.
