Fraunhofer IIS, a world-renowned research institute for audio and multimedia technology, together with Bang & Olufsen and Audi, the world's exclusive high-quality audio and video product supplier, announced that they have made breakthroughs in the field of car audio 3D sound technology. Through the tripartite cooperation, the 3D audio solution was introduced into the Audi Q7 concept car and was unveiled on the Audi booth at the Consumer Electronics Show (CES) 2013.
At present, Bang & Olufsen advanced audio system is already an optional configuration of Audi Q7. The concept car unveiled at the Consumer Electronics Show shows how a new generation of advanced audio systems can redefine people ’s expectations for car audio systems.
Denis Credé, Audi AG's sound system research and development director, said: "At Audi, we continue to establish new sound system standards and strive to enhance the experience of music lovers. We believe that the introduction of 3D movies has helped define the important future development of car audio systems: Reproduce music in 3D. 3D sound effects will render 3D music more naturally and excitingly. This technology brings fluid and open sound effects, which is in line with human hearing system. This cooperation with Fraunhofer IIS and Bang & Olufsen enables us to achieve That vision. "
3D sound effects add a new emotional dimension to the user experience
Bjarne Sørensen, senior manager of automotive concept creation and communication, said: "Bang & Olufsen car audio system has a long-standing reputation for its unique ability to transform the car cab into a truly high-end listening room. And related speakers and amplifiers, we add a new and important emotional dimension to the listening experience. The sound experience goes beyond the limited car cab space, enabling a wide range of audio from the open and open space to the simplest environment such as the recording control room Experience.
This new listening experience comes from the precise combination of Fraunhofer's professional 3D sound technology with the acoustic expertise of Audi and Bang & Olufsen. Through detailed analysis based on psychoacoustic knowledge, the new 3D sound system uses detailed analysis of psychoacoustic technology to create a 3D effect for all users' music. This analysis intelligently distributes the input signal to the car speakers, creating a highly realistic 3D sound effect. By simply pressing the buttons of the Audi multimedia interface, users can adjust the settings and customize their personal 3D experience.
Harald Popp, head of the Fraunhofer IIS multimedia real-time system department said: "Based on our technology and experience in the field of 3D audio research and development, the advanced sound system of the Audi Q7 concept car not only creates an impressive audio dimension and sense of space, but The geometric boundaries of the car, and reproduce the truly rich music with extreme precision, bringing an unparalleled music experience. We are very happy to have the opportunity to work with Audi and Bang & Olufsen to develop a unique sound system. "

This concept car is driven by a new 23-channel DSP Most amplifier, with 23 active speakers and more than 1500 watts of amplified power. The carefully selected speakers not only add points to the car's internal structure, but also produce a unique music listening experience comparable to the sound effects in the auditorium.
There are two speakers in the center of the instrument panel (tweeter and broadband speaker)
There are two tweeters (left / right) combined with acoustic lens technology on the dashboard
Each A-pillar is equipped with a mid-high tweeter
One tweeter for each A-pillar
Two speakers are installed on each front door-woofer and midrange speaker
Each rear door is equipped with 3 speakers-woofer, midrange speaker and a tweeter
Each D-pillar is equipped with two surround speakers-tweeter and broadband speaker
Install a closed subwoofer speaker in the spare tire room
All speakers are covered by a high-grade aluminum grille, reflecting the excellent quality inside the car. In addition, the two instrument panel speakers use Bang & Olufsen's patented acoustic lens technology to accurately reproduce the sound. The first application of acoustic lens technology is to configure the Audi A8. Its main advantage is that it can evenly disperse high-frequency audio, expand the audio range to 180 degrees and limit vertical reflection, so any place in the car can feel rich Sound effects.
