Abstract:
A signal processing apparatus (100) for a hearing aid with a controllable directional characteristic is provided which comprises a directional controller (10) receiving first and second microphone signals (20, 30) and output an output signal (40), a signal analyzer (70) which detects whether at least one of said first and second microphone signals being undesired signals, and wherein said directional controller minimizes the output signal by adjusting the directional characteristic only if the signal analyzer has detected undesired signals.
