Thomson Brandt of Villingham in Germany is patenting what they hope is a more
realistic approach to stereo and surround sound (W0 98/20706). When real sounds
come in through an open window, we can distinguish a car horn from a street
musician, because their sounds take different routes to the ear. Thomson Brandt
want to develop loudspeakers which behave like 鈥渁coustic windows鈥� into a room.
When a recording is made, the sound from each instrument is processed by varying
its level depending on its distance from the microphone. When replayed these
levels are recreated producing a more realistic sound claims Thomson.
