That is why AUDI built its own reference listening room with a high-end system. Where sound is concerned, customers wish for a sound that at least reaches the level of the music system in their living room. Without music, the test subjects’ heart rates were significantly higher. For their experiment, they sent women between the ages of 18 and 23 on 20 minute trips on various days through a major city during rush hour – once with music and once without. Additionally, music in the car relieves stress, as researchers at São Paulo State University (UNESP) in Brazil recently learned. According to a study by the International Federation of the Phonographic Industry, 70 percent of music lovers like to listen to music best while driving. That is because the car is specifically where people listen to music enthusiastically and frequently. When buying a car, many customers pay particular attention to the audio system. “With the current advanced system, musicians can even hear what kind of wood it is.” Difficult, more difficult, interior acoustic space “To give you an illustration, in the past, customers with the system integrated into an Audi have heard that the percussion sticks are made of wood,” says Jähn. The sound has to be clear, precise, and dynamic. That person has to want to hear that piece of music in the Audi. To that end, the experts have a firm principle: whenever someone gets into an Audi with their favorite music, the sound has to have an immediate emotional impact. Wolfram Jähn, an audio developer at Audi since 1999, and his colleagues in sound design want to do justice to an extremely wide range of listening habits. On the contrary, a holistic frequency response is critical for a natural listening experience. At the same time, low frequencies cannot function separately on the floor or high frequencies on the roof. The positive effect of mid-level frequencies on the human psyche serves as a benchmark. The typical Audi sound should be natural and give passengers the feeling of being completely surrounded by the music or speech. Be it a violin concerto, an operatic aria, a radio drama, hip-hop, or a warning signal: Audi’s sound designers have set the highest goal for themselves: reproducing sound in the way that soloists, bands, speakers, or orchestras recorded it.
