Abstract:
A hearing device having three microphones (m1, m2, m3), all of the microphones collectively providing microphone signals, and two processors, wherein the microphones are electrically coupled on a pair-wise basis (m1, m3; m1, m2) to the first and second processors, each of the first and second processors comprising:a first summer for providing a difference signal of two of the microphone signals applied to said each processor; an integrator connected to an output of the first summer; an output, for further processing in a reproducer, being connected to the processor so as to define a processor output; a second summer for providing a sum signal of said two of the microphone signals; a proportional amplifier connected to an output of the second summer; and a third summer coupled to outputs of the proportional amplifier and the integrator and providing a sum signal of the output signals of the proportional amplifier and the integrator, an output of the third summer forming the processor output; and wherein: the output of the third summer of the first processor is connected to an input of a low-pass filter; the output of the third summer of the second processor is connected to the input of a high-pass filter; outputs of the low-pass filter and the high-pass filter are connected to corresponding inputs of a fourth summer for providing at an output thereof a sum signal of the output signals of the low-pass filter and the high-pass filter and an output of the fourth summer forming a device output signal for further processing in a reproducer.
