Abstract (en)
[origin: WO9101616A2] By means of an iteratively produced shift in both acoustic-transducer systems of a stereo headset, the shift being principally downwards and forwards with respect to the line of vision, starting from the reference position used in conventional acoustic-transducer installations in the earpiece, an auditory event is produced which is located substantially horizontally in front of the listener. The most important component of the empirical iterative process is a compensating shift in the headphone acoustic transducers by vector addition in a downwards direction relative to the up-in-head localization which usually occurs with head-specific exposure to acoustic waves. The frequency-dependent differences in sound level which occur, in contrast to conventional acoustic-transducer installations, as a result of this combined shift in the acoustic-transducer systems are used in the same way for a separate multi-channel antidistortion concept in conventional stereo headphones to give an individually simulated "horizontally in front" auditory environment. Sound stimuli of this kind located horizontally in front of the listener are produced independently of the recorded sound and recording technique to be reproduced by the stereo headphones. The result is an increase in quality of the auditory events generated by the stereo headphones in the context of the multi-dimensional reproduction in space of concert-hall acoustics for instance.
