HEARING ASSISTANCE DEVICE COMPRISING AN INPUT TRANSDUCER SYSTEM

摘要

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.
