Dolby headphones: Designates a technology that enables the listening impression of a 5.1 surround system via conventional stereo headphones. The technology used corresponds to a virtual artificial head.
Here the Ton digitally distorted from each of the 5 sound channels in such a way that the brain perceives it as coming from a certain direction, e.g. B. from a loudspeaker behind the listening position. In contrast to previous solutions, Dolby Headphone also includes the acoustic structure of the imaginary room by simulating reverberation and adjusting the time delay of the individual, virtual sound sources.
Although humans can locate sounds with two ears from all 3 dimensions, audio engineering now uses up to 7 loudspeakers to represent spatial sound. Dolby Headphone reduces the technology back to 2 "loudspeakers" within the headphones, although so far only the listening impression of a 5.1 system has been achieved.
