Hearing assistance device comprising an input transducer system
First Claim
1. A hearing assistance device adapted for being arranged at least partly on a user'"'"'s head or at least partly implanted in a user'"'"'s head, the hearing assistance device comprising:
- an input transducer system that includesan audio input transducer for picking up a sound signal from the environment and providing an electric audio input signal, anda first supplementary input transducer for picking up a sound signal from the environment and providing a first supplementary electric input signal;
an output transducer for converting a processed output signal to a stimulus perceivable by said user as sound;
a signal processing unit operationally connected to said audio input transducer, to said first supplementary input transducer, and to said output transducer, said signal processing unit being configured for processing said electric audio input signal, and said first supplementary electric input signal, and for providing said processed output signal; and
a howl detector for detecting occurrence or build-up of feedback howl, whereinsaid audio input transducer is adapted for being located in an ear of said user,the signal processing unit is configured to provide that said processed output signal, in a feedback mode of operation of the hearing assistance device where feedback howl is detected by the howl detector, originates fully or partially from a supplementary input signal that includes said first supplementary electric input signal, andthe signal processing unit is configured to provide that said processed output signal, in a normal mode of operation of the hearing assistance device, originates from said electric audio input signal.

Abstract
The application relates to a hearing assistance device (HAD) comprising (a) an input transducer system comprising (a1) an audio input transducer (AIT), and (a2) a first supplementary input transducer (SIT1), (b) an output transducer (OT) for converting a processed output signal to a stimulus perceivable by said user as sound, and (c) a signal processing unit (SPU) operationally connected to said audio input transducer (AIT), to said first supplementary input transducer (SIT1), and to said output transducer (OT), said signal processing unit (SPU) being configured for processing said electric audio input signal, and said first supplementary electric input signal, and for providing said processed output signal. The audio input transducer (AIT) is adapted for being located in an ear of the user. In a NORMAL mode of operation, electric audio input signal is processed in the signal processing unit and the supplementary electric input signal(s) are used to control the processing.
