摘要:
The application relates to a hearing assistance device (HAD) 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 (a) an input transducer system comprising (a1) an audio input transducer (AIT) for picking up a sound signal from the environment and providing an electric audio input signal, and (a2) a first supplementary input transducer (SIT1) for picking up a sound signal from the environment and providing a first supplementary electric input signal, (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 application further relates to a use of the hearing assistance device. The object of the present application is to provide an improved hearing assistance device. The problem is solved in that the audio input transducer (AIT) is adapted for being located in an ear of the user, e.g. on the front side of pinna for picking up a sound signal from the environment and providing an electric audio microphone input signal. 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. An advantage of the disclosure is that a hearing assistance device with good sound quality as well as directionality properties can be provided. The invention may e.g. be used in hearing aids, headsets, ear phones, active ear protection systems, and combinations thereof.
