In the post below I share Nio users post about Dolby Atmos, this technology is super interesting in many ways from the immerse sound experience to the philosophy of a mobile living space. Hope you enjoy the read – EV EDITION
At present, the three NIO models equipped with Banyan intelligent system: ET7, ES7, and ET5 are all equipped with a 7.1.4 immersive sound system that supports Dolby Atmos as standard, bringing immersion to the mobile living space of users and friends. style of listening enjoyment. In addition to being in the car, I believe you have seen “Dolby Atmos” in many other high-end sound experiences. Why has it become the darling of the audio industry? Which technologies make the sound more realistic and powerful? How to bring the experience of Dolby Atmos into the car cockpit?

What is Dolby atmos ? :
Dolby Atmos (Dolby Atmos) is a movie surround sound launched by Dolby Laboratories Inc in 2012, which was first used in the sound creation of the American Hollywood movie “Brave”. Dolby Atmos breaks through the traditional sound system based on “channels”, expands sound from flat surround to three-dimensional space, and introduces the concept of “sound objects”, so that each “sound object” can Accurately positioned and moved in three-dimensional space, enabling an immersive sound experience comparable to the real world.
Compared to stereo with just two channels/speakers, Dolby Atmos incorporates dynamic objects and a new way of mixing and directing sound from playback channels to put the listener front or center in the soundstage.

It breaks through the traditional concepts of 5.1 and 7.1 dynamic channels, and can combine visual content to fill the space with sound. For example, sound creators can make each instrument sound at a precise position to achieve a more immersive sound effect.
The sound in nature can come from any direction, but the speakers in the sound field are fixed. In order to make a sound closer to the real environment, acoustic experts not only need multiple speakers to create a more three-dimensional space, but also need to allow each sound object in the sound to have its own position, size, movement trajectory and other characteristics.

Today, listeners can experience extremely immersive sound effects in any NIO model that supports Dolby Atmos. It is very challenging to bring Dolby Atmos technology into the car. Because the cockpit is not a flat space, the seats, upholstery and even the steering wheel can interfere with the transmission of sound. At the same time, passengers are not located in the center of the cockpit, and a good experience requires passengers in different positions to feel the charm of immersive sound.

Acoustic experts not only need to measure the frequency response of all speakers in different seats in the cockpit, but also need to optimize the basic signal, delay and other factors. For NIO models, this exclusive customization solution is jointly completed by acoustic experts from NIO, Dolby and Dirac.

As an important part of the NIO PanoCinema panoramic digital cockpit, Dolby Atmos is linked with AR viewing and in-car atmosphere experience, bringing immersive and pleasant audio-visual enjoyment. As more and more Dolby Atmos music content is registered in the NIO Immersive Sound Zone, and richer AR film and television content is launched, we will fully experience the charm of “sound” in the mobile living space.
