A signal processing apparatus for a hearing aid with a controllable directional characteristic is provided which comprises a directional controller receiving first and second microphone signals and output an output signal, a signal analyzer 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.
L'invention concerne un appareil de traitement de signal (100) pour une prothèse auditive présentant une caractéristique directionnelle pouvant être commandée et comprenant un contrôleur directionnel (10) recevant des premier et second signaux de microphone (20, 30) et émet un signal de sortie (40), un analyseur de signal (70) détectant si au moins un des signaux de microphone est indésirable. Le contrôleur directionnel réduit au minimum le signal de sortie par réglage à caractéristique directionnelle uniquement si l'analyseur de signal a détecté des signaux indésirables.
