● Active sound technology to create a sound theme compatible with brand/vehicle positioning.
To tell the truth, when I first heard about active acoustic technology, I didn’t quite understand it. I didn’t know what kind of function it was. Later, after in-depth understanding, I found that "initiative" here refers to the intention of the manufacturer, while "sound" refers to sound, prompt sound and sound effect.
Through sound design, Active Sound combines the overall atmosphere of modeling, interior decoration and lighting to create a harmonious driving environment integrating vision, touch and hearing, and endows BYD’s exclusive sound with connotation and emotion.
The types of active sounds include warning sounds, such as seat belt warning, gear shifting, steering, double flashing and radar warning; Brand-specific sounds to enhance the experience, such as start/stop, welcome sound and sports sound. The exhaust sound generated by the popular sound wave system is actually one of the forms of active sound.
● How does the initiative of Dynasty brand and Ocean brand sound?
The theme of the active voice of Dynasty brand series cars will be national style and national tide, based on China five-tone style, which is elegant, atmospheric and has traditional cultural heritage. For models named after different dynasties, the active sound will be played by typical instruments of different dynasties, and the consonants will be integrated into the notes of subdivided models. For example, the theme sound of the power-on and power-off of the Tang model is mainly pipa timbre, which is smooth and elegant, calm and textured. The Yuan model takes guqin as the theme tone, and birds and whistles are added to the consonants, reflecting the outdoor, natural and young rhythm.

The theme of the active sound of Ocean brand series vehicles is natural fashion, the theme is minor in music, and the sound of waves is consonant, which is lively, smooth and rhythmic. Marine life series models introduce dolphins, seagulls, (|) and other beautification bionic sounds to increase interest and vitality. Warship series models introduce the sound elements of departure whistle and waves beating the hull, which is unique.

At present, the active voice of dolphins has been pushed to customers’ vehicles through OTA upgrade. In the video above, Han’s active voice is a test version, which will be different from the final version.Active acoustic technology is expected to be pushed to Yuan Plus, Seal, 2022 Han/Tang under BYD brand, D9 under Tengshi brand and subsequent new models one after another this year..
● BYD Active Sound Development Course
BYD Active Sound Project was formally established in February, 2021. It adopts multi-department and cross-disciplinary cooperation within the enterprise and cooperates with ——ANSYS, the world’s largest simulation technology company, outside the enterprise.
The subjective evaluation of active sound by the internal listening group in April 2021 is a very important time node, and the evaluation result has become one of the important reference factors for subsequent design and development. The ratio of male to female in the internal listening group is close to 3:1, and the ratio of people over 30 years old and under 30 years old is close to 1:2. These listening staff come from different positions of BYD, including designers, engineers, sales and administrative personnel.
As we can see from the above picture, the frequency spectrum of an active sound is superimposed by the frequency spectra of multiple sound materials. Therefore, both musicians and engineers play the role of creators in the development of active acoustic technology.
BYD Dolphin’s steering prompt tone is designed in a narrow band, which makes it feel smart, clear and clean. Byd Han’s turn warning sound adopts the way of designing the main and consonants separately. The consonants are broadband audio, presenting a pleasant and textured sound. The creation of active sound not only needs musicians to provide creative inspiration and materials, but also needs engineers to engineer the sound, so only the musicians and engineers can work together to achieve excellent results.
● Musicians behind BYD’s active sound music
BYD hopes that the sound source of active sound comes from musical instruments and natural sounds, rather than the more common mechanical sounds and electronic synthetic sounds. So I found Fang Yi, a famous music producer and impromptu piano instructor in Guangdong. Another more important reason for BYD’s cooperation with Fang Yi is that Fang Yi is more willing to cooperate with BYD’s engineers to explore more possibilities of active sound design, rather than just providing music material creation services.
As mentioned earlier, the music materials played and produced by Fang Yi will not be directly applied to the car, but need to be redesigned and optimized by professional sound design software to form a sound source library and finally implemented in the car. It is the close cooperation between "engineering male" BYD and "Artist" Fang Yi that enables the active acoustic technology to be put on the new car in such a short time.
● Full text summary:
From the actual experience, BYD’s active sound technology can provide users with a novel auditory experience above quietness, which can be better realized in cars of this level and with good quietness. BYD’s active sound technology has given different sound themes to each of its brands. The models under the brand adopt a unified melody, but each has its own personality in sound details, showing a unique charm of harmony but difference. This enhances the recognition of vehicle brand on the sound level, and highlights BYD’s strong brand confidence. (Photo/Text/Photo/car home Chang Qinglin)
