Bang & Olufsen has partnered with Audi and Fraunhofer IIS to create a revolutionary 3D sound experience in the car.

LAS VEGAS – High-end home audio maker Bang & Olufsen is part of a unique three-way industry partnership along with Audi and Fraunhofer IIS,  the main inventor of mp3 recording format, that produced a concept car that may redefine expectations from OEM car audio systems.

The Audi Q7 unveiled at the 2013 Consumer Electronics show in Las Vegas uses revolutionary new 3D audio technology to create a
stunning sound experience.

The Bang & Olufsen Advanced Sound System is already available as
an optional feature in the Audi Q7, however the CES concept car demonstrates how the next generation of the Advanced Sound System redefines what buyers can expect from an in-car audio system.

“At Audi we strive to improve the experience of music enthusiasts by consistently setting new benchmarks with our sound systems,” said Denis Credé, head of sound system development, Audi AG. “We believe that the introduction of 3D movies has helped to define the next major step forwardfor in-car sound systems: the reproduction of music in the third dimension. The 3D acoustic dimension of music recordings is reproduced more naturally and more inspirationally than ever through 3D sound. This produces an airiness and openness of the acoustics which corresponds to human hearing. With Fraunhofer IIS and Bang & Olufsen we have partners with whom we were able to jointly realize this idea.”

“Bang & Olufsen Audio Systems for cars are widely renowned for their unique ability to turn a car interior into a real high-end listening room, and with the addition of the 3D sound algorithm and associated speaker units and amplifiers in this Audi Q7 Concept Car, we add a new important emotional dimension into the listening experience,” said Bjarne Sørensen, Senior Manager Car Concept Creation and Communication.

This listening experience is based on a sophisticated approach combining the expertise of the Audi and Bang & Olufsen acoustic engineers with the 3D sound know-how of the Fraunhofer team. The new 3D sound system takes any music of the user to the third dimension by a careful analysis built on psycho-acoustic knowledge. With just a push of a button on the Audi Multi Media Interface, the user can adjust the settings and produce an individual level of 3D intensity.

The concept car has 23 active loudspeakers and more than 1500 watts of amplification power, driven by a new 23 channel amplifier. The loudspeakers have been specially selected to compliment the architecture inside the car and create the unique sense of listening to music inside a concert auditorium.
• Two loudspeakers in the dashboard center (tweeter and broadband)
• Two tweeters in the dashboard (left/right) with acoustic lens technology
• One mid-high loudspeaker in each A pillar
• One tweeter in each A pillar
• Two loudspeakers in each front door with a woofer and a midrange
• Three loudspeakers in each rear door with a woofer, midrange and a tweeter
• Two surround loudspeakers in each D pillar, consisting of a tweeter and broadband
• One closed subwoofer box in the spare wheel compartment

The two dashboard speakers use Bang & Olufsen’s patented acoustic lens technology for accurate sound reproduction. The Acoustic Lens Technology was first fitted to the Audi A8 and its major benefit is the way it uniformly disperses high frequencies, broadening it to 180 degrees while at the same time limiting vertical reflections. This provides detailed acoustic staging from any seat of the car.
