More Information
Summary:A hearing assistance device (40), comprising: two transducers (12,14) which react to a characteristic of an acoustic wave to capture data representative of the characteristic, each transducer being located adjacent a respective ear of a person wearing the device; a signal processor (62) for processing said data to provide relatively more emphasis of data representing a first sound source (T) the person is facing over data representing a second sound source (J1-J9) the person is not facing, such that acoustic energy from the first sound source will be passed through to that person's ears unattenuated, and as acoustic energy sources get progressively more off axis the acoustic energy from those sources is progressively attenuated; a speaker (68,70) which utilizes the processed data to reproduce sounds to the person; an active noise reduction system that provides a signal to the speaker for reducing an amount of ambient acoustic noise in the vicinity of the person that is heard by the person.
