...as long as loudspeakers remain audible, we are not really faced by a proper wave fild synthesis system. The reason for the described problem is not the wave field synthesis principle itself, but its reduction at a single loudspeaker row. If we come closely at such array, say 5cm distanced, we can hear the single loudspeaker nearly 20 dB louder as the "parallel" wave front in 5 meter distance. Really parralel wave fronts from a wfs loudspeaker wall doesn't lose level by distance. Immidiately at the speakers the level is the same as in 5 meter distance.I was trying estimate the position of Advanced Acoustics wfs wall with closed eyes during reproduction of a parallel wavefront. I was hitting the wall by my nose for discover the position in the room.
