Abstract
There is disclosed a sound processing device (300) configured to apply a frequency shift to at least one frequency component of a received sound signal and to amplify at least part of the received sound signal. The processing device (300) is also adapted to generate an estimated feedback signal for combination with the received sound signal via a phase inverting feedback canceller (314). Associated methods (400, 600) of processing a sound signal are also disclosed.
