  • Patent number: 4589128
    Abstract: A process for the reproduction of a sound recording using headphones as the reproduction device, comprising connecting between the sound carrier and the reproduction device a reverberation reproducer, producing reverberation reflections within a period of approximately 50 ms, at least some of which if triggered by pulses occurring simultaneously in both channels of the sound carrier are delivered at time intervals from each other so that they are perceived by the listener as sound-intense signal reflections by themselves, at least some of the single reflections consisting of two pulses being triggered by a direct sound pulse from a channel of the sound carrier and of which the first is emitted over the channel of the reproduction devices that is assigned to the corresponding sound carrier channel and the second is somewhat weaker and is emitted over the other channel of the reproduction devices with a time delay with respect to the first pulse of approximately 0.
