摘要

Constitution It is the hearing aid which has the plural microphones, this hearing aid the 1st microphone which converts sound to the 1st aural signal and the 2nd microphone which converts sound to the 2nd aural signal, following description above the 1st and 2nd aural signal to mixture ratio, connecting, the directivity processing expedient which forms the spatial signal, the 1st acoustic feedback signal which enters into the 1st microphone or the presumption expedient which presumes the 2nd acoustic feedback signal which enters into the 2nd microphone, does not exceed the result largest profit limit which is guided from the 1st and 2nd acoustic feedback signal and mixture ratioProcessing the above-mentioned spatial signal by applying profit, it has the processing expedient which forms the audiometric hearing loss compensating signal, and the output transducer which converts the audiometric hearing loss compensating signal to acoustic output.
