ABSTRACT:
A stereophonic microphone system for improving stereophonic hearing utilizes intensity stereophonic and/or time difference stereophonic pickup methods with the use of replicas of the human head. The microphones are mounted in the replicas of the outer auditory meatus. The replica of the human head is limited to replicas of the pinna with outer auditory meatus. In addition to the known stereophonic recording device used as a position association stage, two replicas of human pinnas are used, with pressure microphones in each opening of the auditory meatus as a shape association stage. The pinna replicas are arranged spaced apart and oriented on the human head or closely next to each other with the same orientation. The pinna replicas are arranged preferably immediately adjacent the arrangement of known directional microphones for the interaural sound recording in the horizontal and median planes. As a result, in addition to the proven technology of intensity and/or delay stereophonics in the frequency range below approximately 1500 Hz, interaural resonances become effective in the horizontal and vertical plane through the pinna replicas in the frequency range above approximately 1500 HZ. It is significant that here signals are created which are as incoherent as possible in order to avoid, particularly in head set reproduction, a localization in the head or the proximity effect at the ears.
