Abstract (en)
[origin: EP1542502A2] The device has two sound transducers (3,17;7,8) per hearing capsule (1,6) for left and right arranged non-centrally relative to the normal central sound transducer position in front of the ear canal and a sound signal feed device (9-11,16) for supplying the sound transducers with stereo sound signals and for conditioning the signals relative to each other in relation to phase angle and/or level so that an original signal is fed to one of the two sound transducers while the other signal is fed to the other transducer with phase rotated and/or level reduced.
