Creating the perfect surround sound with five soundboards

Bending-wave vibrations that turn the entire speaker surface into a soundboard are generated through a special amplifier system and small oscillating coils on the back of the purSonic® boards. The benefit of this technology, which is based on a Siemens patent, is that the sound is emitted at angles four times greater than those from traditional speakers, so that it travels throughout the entire room. As a result, even "difficult" rooms with lots of angles and corners receive a much better sound. You need five soundboards to achieve the perfect surround sound.
purSonic® has now spread from Germany to the rest of the world. There are already dozens of specialist companies across Germany who know exactly how the soundboards have to be positioned and installed in walls, ceilings and floors to achieve the best sound results. After that, the slimline "speakers" can be covered over with wallpaper, tiles or plaster – without compromising the quality of the sound. Puren has tested its "wall of sound" extensively. Following an 18-month development period, the sound system was launched on the German market in summer 2004. Meanwhile, the formulation for the polyurethane remains a secret. Hans Bommer, Managing Director of Puren, comments, "All I can say is, it took hundreds of attempts to arrive at the sound we were looking for."
Gerd Dressen from Bayer MaterialScience Communications has no doubt that purSonic® points to the future. "Conference rooms, concert halls and churches will now be able to achieve sound effects that they would never even have dreamt of in the past. Who knows, maybe drivers will soon be listening to their favorite tunes coming from their car’s roof liner?" The new technology can even output a high-quality sound through marble up to 2 cm thick, meaning listening to Vivaldi in your luxury kitchen is now a real possibility.
And back on the topic of music, the boffins at the Creative Center are now, quite appropriately, listening to the classic Pink Floyd song "Money". The legendary jingle of the cash register fills the entire room. "We'll have to wait and see how quickly purSonic® penetrates the market," says Foltin. And it goes without saying that he too can hardly wait to hear the perfect purSonic® surround sound from his own four walls. And you can bet the first song he'll play is "Welcome To The Machine" by Waters and the band.
