Dolby Panoramic Sound Technology Analysis: What is Dolby Panoramic Sound supported by car audio for?

Nowadays, the competition of new energy vehicles is becoming more and more intense, and the car audio system is often compared. Yes, the sound quality is now It has become one of the important standards to measure the high-end configuration of new models. This is why Dolby Panoramic Technology has been introduced into more and more high-end cars, and Dolby Panoramic has gradually become synonymous with the sound system of high-end cars.

What is the Dolby panoramic sound technology used for?

Dolby Atmos is a surround sound coding technology launched by Dolby. It uses physical and psychoacoustic principles to create immersive audio experience for users. The core idea of Dolby Panorama Sound is to use high-precision spatial coding to expand the sound from conventional horizontal surround to panoramic stereo surround. This technology can not only accurately present the horizontal sound field received by the human ear, but also create a sense of space in the vertical dimension by introducing height information, making the sound seem to come from above or below. In addition to expanding the sound field dimension, Dolby Panorama also uses a variety of patented technologies, such as object based coding, mute data coding, etc., which greatly improves the overall sound quality performance of music.

Is this technology suitable for use in cars?

In the automotive audio system, Dolby panoramic sound technology is applied in two aspects. First of all, on the hardware level, it is necessary to carry a chipset that supports Dolby's panoramic audio decoding, and reasonably arrange the speaker array according to the compartment space design. Generally, The automobile manufacturer will cooperate with Dolby's professional engineers to carefully design the layout of the loudspeaker in the car. This includes selecting the number, type and location of speakers to ensure that audio can cover every corner of the car evenly and accurately. secondly, Software The system must support Dolby panoramic audio stream decoding and rendering, The sound system of each model will be professionally adjusted according to its internal structure and materials to optimize sound transmission and reduce sound distortion, so as to ensure that every seat can enjoy the same quality of sound. It can be said that only Only a complete set of hardware and software can create an immersive 7.1.4 surround sound scene for the passengers in the car.

In terms of sound quality and experience, the car audio system supporting Dolby Surround Sound is obviously superior to the traditional car audio system. Panoramic sound will truly reproduce the sound information around and above, so that the passengers can be in the scene as if they were in the scene. Especially suitable for movie appreciation and game entertainment. However, the traditional car audio has not been optimized, and the sound field is limited to the horizontal plane, so the sound effect experience is thin and lacks three-dimensional sense. Even if surround sound coding is supported, panoramic rendering cannot be achieved.

It is said that Dolby Panoramic Sound is a revolutionary step for car audio, which has also had a certain impact on consumers' choice of models. Models that support full scene sound often have more advanced sound systems, which can bring passengers a high-quality entertainment experience, which has become a feature of concern to some consumers. For those who pay attention to sound quality and pursue immersive experience, panoramic sound may even become a decisive factor in car selection.

There is no doubt that Dolby panoramic sound technology has brought a new height to the car audio system. Although the current market penetration is still limited, with the maturing of technology and the decline of manufacturing costs, it is believed that more and more models will be equipped with audio systems that support full scene sound in the future. At that time, immersive audio experience will no longer be exclusive to luxury cars, and more ordinary consumers can enjoy the supreme pleasure of audio-visual entertainment in the car.
