Abstract
A device for the stereophonic recording of sound events by means of two microphones arranged with essentially oppositely directed orientation and mounted in 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 the replicas of the pinnae with the outer auditory meatus. Microphones with unilateral pickup effect are used and are mounted preferably in positions corresponding to the positions of the pinna openings in human heads. The microphones operate in the low-frequency range of up to approximately 1500 Hz as directional microphones and, in the frequency range above approximately 1500 Hz, operate with spectral resolution of the outer ear transmission function. The device according to the present invention provides compatibility of headset reproduction and loudspeaker reproduction.
