The Volkswagen Group uses high-end audio company Linn for their Bentley line of automobiles, yet for the new Audi Q7 they are looking to have a staggering 62 speaker system! The Audi Sound Concept project engineered by Peter Gleim, who works in Infotainment Development at Audi in Ingolstadt, has been busy testing the Q7 "rolling hi-fi studio" that takes a radically new approach. The idea behind Audi Sound Concept is a physical principle called wave field synthesis, which states that the front of any individual wave can also be considered as superposition of individual waves. In the world of acoustics this means that a sound wave can be recreated by a multiplicity of small sound sources placed closely adjacent to one another along the wave front. This principle was first put into practice by Dutch scientists in the late 1980s, and it can be experienced today in a movie theater in Ilmenau, in the German state of Thuringia. One of the driving forces in the field of wave field synthesis is the Fraunhofer Institute for Digital Media Technology (IDMT) in Ilmenau. Audi began its development work in collaboration with the IDMT five years ago. The current status of the project is the Q7 prototype, which is parked in a workshop. A powerful amplifier takes up most of the space in the luggage compartment, and thick cables connect it to three PCs. Installed in the Audi Q7 are 62 speakers: 5 woofers and 5 tweeters plus 52 mid-range speakers that are located within the instrument panel beneath the windshield, in the roof pillars and in the doors. Five units are integrated into each door sills. Fuente: www.enjoytheusic.com
