Wave Field Synthesis in the Real World: Part 1 - In the Living Room

In anechoic rooms the concept of Wave Field Synthesis (WFS) has already proven to provide superior spatial sound over a large part of the room. The progress in microelectronics enables WFS to become available in commercial products at reasonable price. In the next future it will be installed in different acoustical environments. In anechoic space WFS needs a huge number of loudspeakers. In "normal" listening conditions simulated and real acoustics interfere with each other making the generated wave field less exact. This paper describes listening tests conducted to evaluate WFS in common living room conditions. Parameters under test are the number of loudspeakers, the distance between loudspeakers, the position of the simulated source and the position of listeners relative to the loudspeakers.
