Abstract:
PROBLEM TO BE SOLVED: To provide a hearing aid system provided with a hearing aid and an external input device configured for transmission of audio signals to the hearing aid.SOLUTION: Hearing aid circuitry 40 comprises a front microphone 42 and optionally a rear microphone 44 for conversion of an acoustic sound signal from the surroundings into corresponding microphone audio signals 46, 48 output by the microphones 42, 44. The microphone audio signals 46, 48 are digitized in respective A/D converters and optionally, in a signal processor 50, processed by a pre-filter and selectively combined for selective formation of an audio signal with directivity and an omni-directional audio signal. The processor 50 is further configured to generate a hearing loss compensated output signal 52 that is input to a receiver 54 for conversion into acoustic sound for transmission towards an eardrum of a user of a hearing aid system 10.
