Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To remarkably enhance a directivity characteristic of a microphone in the case that an external noise deterioration in articulation of a hearing aid by means off the directivity of the microphone. SOLUTION: A reception array 5 consisting of microphones 1, 2, 3 of a plurality of channels is placed on a frame of an eyeglass mount tool or a support beam of a headphone mount tool. An output of each microphone is Fourier- transformed (6) to obtain an amplitude and a phase spectrum and following operation for each frequency band are conducted. An optional coefficient is multiplied with a phase difference between channels to extend (11) the difference, the amplitude and the phase between channels are interpolated to multiply (16) number of channels to an optional value. An optional weight function is multiplied (21) with the outputs to apply phasing and summation (26), the result is inversely Fourier-transformed (27) and the result is given to a conventional amplifier input.  Phase difference between channels is extended, number of channels is multiplied, the directive width is decreased and external noise elimination performance can considerably be improved.
